#4069 Null Vs. Direct Output

Posted by darbonne on 17 February 2012 - 06:18 AM

I am using jPlay with J River and have set the software settings as noted in the setup. The setup calls for the output to be set Null. When I do that I completely lose the sound. When I set it back to Direct it works. Which is the correct setting for jPlay?/wp-content/forum-smileys/sf-confused.gif

#822 DAC recommendations for Jplay

Posted by Marcin_gps on 14 July 2011 - 09:41 AM

Hi everyone,    I've been searching for a good USB/Firewire DAC (or DAC+USB-to-S/PDIF combo) for few years now. Ideally I would like to have one-box solution with support for all sample rates up to 192kHz over USB/FW. Headphone amp, balanced outs are not required. Right now I see few candidates. I would appreciate your feedback - if anyone had a chance to audition one of those with jplay - please share your comments (how does it sound, what bitstream size and minimum buffer size). Or recommend other units, that I'm not aware of :)   - Antelope Zodiac Gold + Voltikus - it has everything I'd ever want from a DAC. A bit pricey, but at least I know what I'm paying for.  - Lampizator DAC with USB (async, 32/384) - I had one in my system for a while, but without USB connection. I fed it with RME AES-32 card. The sound was terrific, the best I've heard.  - Anedio D1 - waiting for upgraded version with hi-rez support over USB. - Calyx 24/192 DAC - good USB implementation, ess sabre like anedio, nice looks - Hegel HD20 - nice jitter reduction, found an opinion that it bests Ayre QB9, relatively cheap  - Burson Audio 160D - 24/96 only, great headphone amp, which I don't need (STAX fanboy) - W4S DAC2 - this one uses m2tech drivers so low buffer is possible, but I've seen comments/reviews which indicated it's not that good - db Audio Labs Tranquility - it tempts me the most to try it although it doesn't support hi-rez, it's USB only and NOS - haven't heard one before!   Of course it would be great if I could listen to all of these DACs in my system, but it's impossible, so eventually I'd have to get one in blind. The good thing is that USB-capable converters are getting very popular and there will be a lot of new models soon, hopefully better :)   Cheers,  Marcin

#43338 Jazz trios

Posted by Marcin_gps on 07 May 2018 - 07:16 AM

I know the topic is well known to many music lovers and audiophiles. I'm a huge fan of jazz trios myself; classical, modern, melodious, jumpy - all styles really.

Recently at the local jazz festival in my city (Jazz nad Odra) I discovered a pianist & composer Dan Tepfer. His music and style are so different from what I'd known that I needed a moment to adjust. Once I did, the music really touched me. I can recommend his latest album 'Eleven Cages'. It's available on tidal. Here's a sample, hope you enjoy it:



Have you discovered any interesting jazz trios lately? Please share :)


Best regards,

#45686 Requirements for a dedicated computer

Posted by FelipeRolim on 13 November 2018 - 01:06 AM

Since I had the feeling that the real performance of a stereo system isn't achieved by a desktop blu-ray player, but with a completely dedicated computer, I spent a lot of time on the mission of extracting the best I can from a dedicated computer. For this, many and many hours of studying and listening have brought me to the current stage, with at least one computer that I think performs well. In this topic, my goal is to write some things that I consider for a computer assembly, things that I took into consideration, things that worked for me, and that's why they represent my personal opinion on the subject.


The first thing that I consider essential in a dedicated computer is a linear power supply. First, talking generically, what I have to say is: every low signal source that's part of the system (computer, pre-amp, DAC, e.g.) is extremely more sensible than high signal source (usually amplifiers and integrated amps). It happens because the SNR between them is very small, in direct comparison. For example, a noise of 0,5v represents much more for a circuit with a voltage of 1,5v, 4v or 5v (as in the USB connection, or between DAC and pre-amp, or between pre-amp and amplifier) ​​than for a circuit with 35v signal (amplified output). This makes a special care with noise necessary for our systems, especially high frequency noise. Many people say that electromagnetic shielding is enough, but it just physically isolates the circuit elements. I could, e.g., insulate a transformer with mu-metal, or a power supply, and probably the high-frequency irradiation will be controlled. However, there are other two big strands that are part of the equation: a) controlling EMI/RFI waves irradiation doesn't mean that they won't exist amymore, but just will remain closed. I mean, by enveloping a computer power supply, for example, all radiated noise will be confined within itself, reflecting indefinitely (there is a difference between absorbing and isolating); b ) even with a control of the phisycal incidence of electromagnetical waves, we cannot forget that noise also circulates over the conductors. And not just that. High-frequency noise has no "path", no definite direction. At the same time that it comes with the power cables (phase and neutral), it also returns through the same cables. In a few words, it means that the noise generated by a switched power supply propagates through internal components, spreads to the equipments through the USB cable, the coaxial cable, the RCA/XLR cables and reaches the speakers, but also returns by the electric cables to feed the other equipments directly by the transformer. This is, therefore, a double loss, since, with a switched power supply in the system, everything loses: DACs, preamplifiers, among others, and not just the equipment with a switched power supply. Not long ago I was highly contested in a Facebook group when making these notes, but no one was willing to prove me the opposite with the use of an oscilloscope. It's obvious that's there are linear PSU and linear PSU, switched PSU and switched PSU, and that an excellent switched power supply can be better than a bad linear power supply, but, in principle, working at 60Hz and with adequate filtering (and a few other things), a linear power supply, by its nature, can achieve a better level of performance.


Based on several assumptions, I developed and tested a dozen linear power supplies to arrive at the final form of what I have today. I believe that implementations are possible, but this isn't the focus of my dedication now. The fact is that after I completely removed any and all switched power supplies from my system, the performance level went up severely, and as I was implementing the computer and other items, I noticed that much of what I heard was due to the fact that the computer didn't has a switched power supply, and I was able to prevent it from inserting noise into the network or audio path. So, I consider that the first and one of the most important care of any audiophile that wants to build a digital stereo system is the non-use of switched power supplies and, of course, the adoption of good performance linear power supplies.


In next post, I'll write about the hardware of a dedicated computer (motherboard, processors and others). Hope you enjoy.


PS.: for those interested, I can also talk and explain about the construction of my linear power supplies, already apologizing for my bad English.

#45476 RAMdisk with Windows Server 2016/2019 - Configuration Guide

Posted by FelipeRolim on 08 November 2018 - 02:21 PM

Hello guys. After I spent a lot of time trying to make my dedicated computer work with RAMdisk, I finally managed to succeed in this endeavor. As I tried many different paths, I wrote down everything so that I had some "extra" information when I finally got it, and also to have a guide in case I had to do it again. Well, I didn't have to do it again, hehe, but I hope the information I wrote down as "definitive" in terms of functioning is actually correct and helpful to colleagues in the forum. As I am Brazilian and I wrote the text originally in Portuguese, I spent some time transcribing it into English, so that it is possible to share with colleagues of this forum. I think it's valid, because it really was very difficult to get it for the first time.

For those who don't know, RAMdisk is one of the most high-performance methods for audiophiles in the world, and although I've never read anything about it in this forum and only have a personal friend who has tested before me, I've read a lot, a lot , much information in international scope, where it seems that the theme is more evolved. Reducing latency and high throughput is only a small part of the benefits. If that weren't enough, I've never heard any "original" setup, with SSD, SD card, M.2, or anything else, that delivers audio quality as good as RAMdisk. For me, it's the best, but what I don't know is if there are different RAM models that deliver different sonorities (Corsair vs. Kingston; Kingston vs. Crucial; Corsair vs. GSkill; e.g.).

To make it easier for me and my colleagues, I created a PDF file that can be downloaded, because the text is large and I also attached some images to make the complicated parts more enlightening.

Finally, I remind colleagues that although there are Windows software that makes RAMdisk easily, they only allow a very limited part of RAM to be defined as storage, and they don't allow the operating system itself to be installed or loaded on it. The guide I've tried to create effectively causes 100% of the operating system to go to RAM and run from it.

#44209 How To Identify A True Audiophile Recording

Posted by JazzDoc on 21 August 2018 - 03:14 PM

This excitement regarding audiophile recordings is all very well but how do you know that you are listening to a genuine audiophile recording and not a mere pretender? I hope that the following questionnaire will help:


  1. Is the featured artist someone who you have never heard of?
  2. Are they playing an instrument that looks impossible to tune, much less play?
  3. Does the featured artist spell their name in an unusual way?
  4. Was the recording released by an obscure record label?
  5. Does the music contained in the recording celebrate the cultural diversity of an indigenous people or their country of origin?
  6. Was the recording made using a restored vintage analogue R2R recording device, e.g. Nagra, Studer?
  7. Is the music contained in the recording wholly inappropriate for dancing?
  8. Would you have no wish to see the featured artist in live performance?
  9. Does the featured artist have facial hair? (Please note that this question is also applicable to female artists)
  10. Is it likely that, having listened to the recording once, you would never play it again?
  11. Would the featured artist be unlikely to release a ‘Greatest Hits’ album?
  12. Does the recording enable you to focus on the more detailed mid-range of your most recent system upgrade?


If you can answer ‘Yes’ to six or more of these questions, then you are probably dealing with a genuine audiophile recording. Take comfort in the knowledge that you probably have a great hi-fi system. If not, just file it in the ‘Redundant’ category of your music library, alongside ‘Kind Of Blue’ by Miles Davis and ‘Electric Ladyland’ by The Jimi Hendrix Experience.

#48796 Happy Birthday and welcome AudiophileOptimizer 3.00

Posted by AudioPhil on 31 May 2019 - 03:08 PM

Hello Folks


Today six years ago the very first public version of the AudiophileOptimizer went online, so happy happy birthday AO! 🎂 And here we are, six years and thirtheen versions later going for it one more time! 😎


But this is only the thirteenth official version, in fact between AudiophileOptimizer 2.20 and 3.00 more than 450 internal versions have been compiled while working on it for almost 10 months.The beta phase was around 4 months long letting the feedback from almost 100 testers further shape and finetune the final version of the AudiophileOptimizer 3.00. So as you can imagine this has been a lot of work and this post will highlight many details about it. We've put a lot of links to other posting where you can read much more detailed information about those specific topics.


AO 3.00 is faster than any previous version. It is actually a LOT faster. On systems with slow drives, lets say CF cards for example, it could be a pain launching up AO, it took very long time to start. This is a story of the past now... All this blazing fast speed is due to the new engine we have been working for months... This does not only make things much faster for the end-user, it also makes coding and testing AO much faster. Compiling all components (AO, ST, AS, Uninstaller & Setup) took around 17 minutes before the new engine. With the new way of things compiling all modules takes roughly 3-4 Minutes. Imagine you have to do this process a 100 times in a short frame of time... smile.png


The new engine will also help greatly in the future to adapt AO to new operating systems. As you know in the past a new OS versions always ment months of work to have all working again for the new OS and maintaning functionality for the old ones. With the new engine a new OS will be adapted much faster. Another advantage is that what has been achieved for one OS can now be easily and almost all the time be achieved for all the other OS'es as well. Example, AO 2.20 could enable Device Manger, but only on Server 2016 and not for 2012 R2. AO 3.00 uses the new engine and the result is that we now have the device manager enabled through setup.exe on all three supported server OS's, meaning 2012 R2, 2016 and 2019.


Microsoft makes each Server Core version tighter and smaller. This is for various reasons, they want to lessen the codebase which means less surface for attacks. It also means less downtime of server since they need less updates to be patched and so on. This process of making the OS even smaller and lighter has a price, and the price is functionality. So with each iteration of Windows Server in Core it got trickier to have your media player and especially the Audio stack working again. Bringing back the WASAPI Architecture to Windows Server 2016 was an adventure that took place over three years, so it wasn't exactly easy to accomplish that. With Windows Server 2019 the method of Server 2016 did no longer work and again a lot of time and effort had to be spent to make WASAPI in Core mode available again.


Windows 10 keeps changing every six months, for the good and the bad. Nevertheles the AudiophileOptimizer 3.00 is fully tested on Windows 1903 (Build 18362) which came out barely two weeks ago. So no matter what OS you are running, the upgrade to AO 3.00 is the right choice for sure!

To uprade to AudiophileOptimizer 3.00, simply run the new version of setup.exe over your current installation. Setup.exe can be run in  core,  minimal-server  and  GUI  mode. You don’t have to do a reset via ServiceTool before you run setup.exe. Once setup.exe updates your current version of AudiophileOptimizer, it will automatically launch the latest ServiceTool to make a full reset in the end. If you upgrade AO 2.20 (or older) to AO 3.00, setup will launch ServiceTool 3.00 at the end of the installation process to make that full reset. Since your old Activation-Key will no longer work for the  new  version,  ServiceTool  will  need  a  new  Activation-Key.  Do  not  close  ServiceTool, go to the self-service Activation-Portal and generate a new AO 3.00 compatible Activation-Key and activate ServiceTool with the Activation-Key; this will also activate AO and all other components.


Please feel free to ask anyhting you'd like to know. We really hope you enjoy the latest iteration of the AudiophileOptimizer and we also hope to be around for another 6 years! smile.png



Very best,

#48338 HDPLEX H5 - ASUS P10S WS - INTEL XEON E3 1235L V5

Posted by Carlosoptico on 15 April 2019 - 02:45 PM

Hello friends :
I wanted to talk about a project made with a motherboard and a
processor that has been recommended several times in this forum and
that has kept me busy in recent months: The Asus P10S WS board and the
Xeon E 1235L V5 processor.
I looked in the web and had no problem locating the Asus board, but
the Xeon processor was very difficult to find and when I found one in
Aliexpress for € 78.5, I decided to buy it, without knowing what would
come and in what state it would come. It arrived after three weeks and
that encouraged me to continue with the project.
Then came the Asus board, the Apacer ECC RAM, extended temperature
range, 8 GB in two drives and HDPLEX H5 chassis with the HDPLEX200 and
HDPLEX 400 DC-ATX Hifi converter, which was what was available at that
With everything already at home I got "JPLAY fever" and I ordered a
JCAT USB FEMTO card and a JCAT NET FEMTO. This led me to situations of
doubt with my more stingy self, whether I had overspent the budget,
whether it was worth it, if it would end up working, since it was the
first time I was assembling a PC by myself. I encouraged myself, every
time I put the Lenovo laptop back on with JPlay FEMTO 7.d and I did
some improvements like turning off the anti-virus, deactivating
unnecessary programs and even disabling processes in the BIOS thanks
to the advice in this forum and hearing the results.
Nothing better to put an end to the doubts, than to finally start
assembling my first PC. With the help of the HDPLEX manual and looking
very carefully at the photos, the work was easier than I thought,
although when I had to connect the 24-pin ATX cables between the
motherboard and the HDPLEX400 DC-ATX converter in the place destined
for it, they did not reach, by little, but they did not get to make
contact. I moved the HDPLEX 400 to the left side, but I had to make
two new holes to hold it firmly to the base of the PC. I did not have
any more problems until I put the FEMTO USB card, it was a little
displaced and the USB inputs rubbing the chassis, a thick terminal of
a USB cable could not enter to the end, so I had to slightly deform
the parts that did not fit well in the chassis and the metal plate
that supported the card. In the end everything is perfect. I placed
the NET FEMTO card but when I went to connect it with the PCIE
extender, it had a torsion that I did not like. I decided to remove
the NET card for the time being, I would put it later in another
location and start with the LAN ports of the motherboard. To see if
that worked and I ordered an Intel M.2 SSD 700 series disk for the 256
GB operating system for € 70.To place the start-up LED, I removed the
upper coaxial connector that is next to the lateral USB connectors on
the HDPLEX chassis, which I was not going to connect and I put it in
the space that was left. Everything was done, the only thing left was
to put Windows 10 Pro, JPlay, the Devialet driver and put Fidelizer
8.3 Free.
And it worked . The sound was more elegant, more layers, more defined
and with better timbre than with the Lenovo. It was an improvement,
but after a while I wanted more. I ordered 1 x SSD Apacer Industrial
with memory type SLC and extended temperature range of 64GB, very
expensive, and I got two units. I did not make a claim for this. I
also ordered 8GB of RAM Apacer, to complete the four spaces intended
for RAM after reading an article in the forum, and yes, it sounds
better with the four spaces occupied.
I ordered a JCAT SATA Reference cable and a JCAT SATA HD cable, but
the delivery was delayed due to a mistake and as compensation I
received a prize from Marcin, who sent two Reference SATA.
I re-assembled everything, with the new Apacer SSD disks, one for S.O.
and the other as reference music library and SATA cables. I also put
the NET FEMTO card, but in another place, that although it is very
close to the passive radiator of the CPU, it does not make contact,
after deforming the part that holds the card. I had to remove the
safety on the side that connects with the JCAT NET FEMTO card of the
PCIe extender cable because it leaned on the passive radiator and
forced the position. Now the sound was quieter, more real than with
the Intel M.2 with the S.O. I have put anti-resonant treatment behind
the front of the chassis and under the electrical wiring line and in
the middle of the top cover where I have also put 3M EMI absorber
(5100) which I have also used for the RAM, the JCAT cards fastened
with cable ties and the electric cables and the HDPLEX DC-ATX
converter, USB ports of the motherboard and some free sides of the
chassis, using 3 sheets for everything.
I earth wired the HDPLEX chassis and placed 1 SSD M.2 Intel 700
Series disk of 1TB instead of the Intel SSD of 256GB , to test the
difference with the Apacher SSD of 64GB with the reference library and
I removed all switching source.
I also put a two-meter Oyaide EE / F-S26 mains cable between the
Victron 5000 Va solar converter's electrical box outlet and the wall
socket of the music room, replacing a normal cable. Later I changed
the cable from the wall socket to the 8 schukos power strip with the
same Oyaide EE / F-26 cable of 2 meters in length with Furutech
rhodium F1-E11-N1 and F1-11 connectors and the old Yarbo 8000 for the
Devialet with two Oyaide EE / F-26 with Furutech rhodium connectors of
1.5 meters. Now the TV monitor and the UltracapLPS 1.2 power supply of
the Iso Regen are powered by a 12-volt DC line from the batteries of a
solar system instead of the switch-mode power supplies they brought.
The motherboard, the USB FEMTO card, the SSD Apacer disks and a Hub
with the wireless mouse and keyboard and three 4 TB hard disks (which
I disconnect when not in use) are powered by the HDPLEX 200 with a
Vovox Texture 1 meter cable and the NET FEMTO card for a PSU
Audiophonics 25 with Furutech cable and Furutech rhodium connectors.
Each of these improvements were done one at a time, giving it time to
stabilize and to check whether they were improvements or were a
placebo. This time, after a week of burning the last addition, the
sound is much better, more real. There's a long way to go, put Windows
Server 2019 + A.O. 3 that will be the next improvement. Now I feel
proud and happy of this challenge that has been for me to get to know
JPLAY, the JCAT products, the learning project of making a SINGLE PC
and improving it, the comments from the forum, from Marcin, from
ThuanB and of course from Felipe Rolim and others. Now its time to
listen to the music and enjoy, until the "fever" returns. I have to
say that everything sounded perfect ... until I broke the UltracapLPS
1.0 and the IsoRegen stopped working between the PC and the Devialet.
I took 1 day to order a new one. I could not live without it, so I
want to thank Alex Crespi for the excellent product he has created and
Larry from HDPLEX for the good service given when necessary. The next
thing I would like to try is the dual PC, first with the Lenovo laptop
+ SINGLEPC and later, who knows, a new PCAudio, the same one but with
the HDPLEX 400.

#35154 Infinity Blade HQ (Bug Head Emperor) worth trying

Posted by franran on 18 March 2016 - 01:47 AM

I don't understand a word of Japanese, except arigato. Any correspondence I have had with him has been very confusing. I have much compassion for a mentally ill person. Despite his severe psychosis, Hiroyuki has managed to create the best audio player on the planet. I am very grateful to him and support him spiritually...and occassionally otherwise. He knows that I genuinely care about him. I pray that he finds mental peace. Someone without compassion might find his illness a bother. I don't. It makes me admire him more for what he has accomplished. There are people who don't appreciate what he has created and given away for free. They personally attack him. That is not delusion, it is fact. The world is full of unhappy people who would do this.


He has a little music system, inferior to most systems on this forum. He only currently has Windows 10 to develop from. He can not troubleshoot problems pertaining to other OSs. He knows that those with Windows 7 and 8 can update for free to Windows 10, which sounds better anyway. He allows WS2012 R2 to load his player, but in no way supports it. It doesn't work well for me anymore so I don't use the new versions. It is okay. 6.66 is a wonderful gift from a brilliant man in Japan.


I accept problems in life and look for solutions where they can be found. The solutions often lead to better things than what was had before "the problem" was encountered .

#45707 Requirements for a dedicated computer

Posted by FelipeRolim on 13 November 2018 - 03:29 PM

The second thing that I consider essential is the hardware, and, in this point, I'll allow myself to extend a little bit more, once it divide in a lot of subjects that need analysis. To facilitate, therefore, I'll separate by subitems:


a) absence of moving parts: the moving parts of a computer consist, basically, of coolers and hard drives. These two things are powered by motors that, apart from being noisy mechanically, are high frequency noise generators, even on a small scale, which reflect indefinitely by the computer. Some people say that, to avoid this problem, external power and a few filters are enough, and the noise won't be audible anymore. I disagree. I've already tried to power my HDD and a cooler with an external power supply, and even with a 5v battery (20000mA power bank). It didn't work. The motors not only generate noise from the cable that powers them, but also emit electromagnetic waves that spread without direction. Since motherboards have very sensitive and microscopic rails, and the processor, memories and internal controllers already work at high frequency, this noise, in the house of MHz and even GHz, generated by the motors, affects the boards and the cables and cause distortions, harmonics, and this reflects in the loss of quality. It's worth remembering here that the computer is the birth of the audio, and that the digital information can be lost and/or distorted until reach the speakers. So, the more care you take with intrusions, the better it will be for the end result, and all of this is perfectly audible. It's also worth remembering that the electric power also makes noise and, especially on the motherboard, this is audible and deserves special care..


Some people maintain that this way of thinking (loss or distortion of computer information) became obsolete with the advent of asynchronous DACs. Well, if it is true, and if the data is buffered previously in the DAC, then, doesn't make sense that devices like ISO Regen, UltraRendu, JCAT USB Isolator and other things bring a positive result. Even a few USB/SPDIF interfaces, such as Mytek, Audiophilleo, SOtM dx-USB HD, M2Tech HiFace would work just as well, instead of the USB connection. What I think is that the purity of the circuit as a whole is, yes, one of the key points of the overall yield. As a solution, I defend the use of solid state storage and passive cooling.


b ) the fewer onboard controllers used, the better. We know that a computer has a lot of onboard controllers, like SATA, RAM memory, VGA, LAN, USB, PCI-Express, processor clock and many others. In my experiences, I noticed that, the smaller the number of controllers in use, the better, clearer and more faithful the audio, and the closer it gets to the analogue, and it gains attributes of microdynamics, decay, spatiality and fidelity of tones and harmonic body. The controllers work at high frequency, and this generates electromagnetic noise that affects everything inside the PC, from the cables to the boards and storage devices.


To allow the use of the controllers in a small number, we must connect to the computer as few elements as possible, and it mean using only USB, LAN and power connections, externally to the computer. The USB connection is only for connecting the PC to the DAC. The network connection is used to connect one PC to another, as well as to control them remotely. There's no need of video connection, mouse/keyboard connections, external hard drives connection. Everything else is completely unnecessary to the audio playback (this is, in my opinion, one of the reasons for why a notebook or a Mac Mini aren't so good as a desktop computer: they have unsurpassed rigidity in hardware set-up). This means that the VGA controller, the integrated USB controller, the fan speed controller (point "a" above), the mouse and keyboard controller and some others, are not in use, at least actively, and only the essential ones remain active for correct operation of the computer and for musical reproduction. From what I've heard, the worst controller for the audio quality is the VGA one. The onboard USB brings a bit of noise, but on a smaller scale, it's something less obvious, but with which I do not want to hang out. This can all be achieved in the absence of a monitor, using a mobile phone or tablet for remote control, and when longer maintenance is required, with remote access via another computer or notebook. Video connection, never.

c) the fact of having hardware is not enough for good performance. You also need to adjust the hardware: in my research, I came across instruction manuals from Computer Audio Design, Computer Audiophile, Fidelizer, and a few others. Each one has its own ideas, and through reading and listening, I have tried to bring together the best of all in a material I have assembled. Several manuals argued that certain features inherent in the motherboard and processor would be harmful to the audio and should therefore be disabled. As in this hobby we cannot believe everything, but also can not doubt anything, I tested what was recommended, one by one. I absolutely disabled everything related to Intel SpeedStep, Turbo Mode, C-States, Virtualization Technology and Hyper-Threading (Audiophile Optimizer recommendatoin). I found improvements in audio quality, but the most vital was Hyper-Threading. This detonated the sound quality. I noticed that this all caused the processor cores to work very unsteadily with energy, now consuming more, and heating more, and now consuming less, for cooling and energy saving. This v-core oscillation, however, brought dirt to the sound, and the deactivation left the frequencies of the cores locked at a fixed value (2GHz) and the sound more fluid and clean. I also deactivated the onboard audio, the SERIAL driver and the USB 2.0 drivers (I only left 3.0 port active) and decreased the video memory to 64MB (in particular, I also deactivated the Audio-PC SATA controllers). I left HPET (High Precision Event Timer) enabled.

Having said that, I ask the license to digress a little to talk about something important: for those who don't know, Hyper-Threading is a feature that processors use to execute multiple threads (threads) in a single core. The practical result of this is that, with it active, Windows "sees" the processor with twice as many cores and processing performance goes up. Therefore, a Core i3 has two physical cores and four virtual cores, as well as some Core i5. Some Core i7 have four physical cores and eight virtual cores, and so on. There are some Intel Xeon with ten physical cores and twenty virtual cores. As a consequence, with Hyper-Threading disabled, a Core i3 processor works only with two cores, as well as some Core i5. This in essence. In addition, disabling the Turbo Mode prevents the processor's frequency from rising beyond the base. It turns out that, because of this sum, performance drops substantially, and then that very good processor with a very high benchmark, isn't so good anymore. The latency of this whole process is very low and more than enough, and the processing is far from itself limit.

I say all this to come to the conclusion that a processor of very high performance isn't essential for high fidelity audio, except for three exceptions that I want to mention in the sequence. To elucidate, let's take as example two processors, a Core i3-6300T and a Core i5-6400T. The first, with Hyper-Threading disabled, will only have two cores working at 3.30GHz. The second, with Hyper-Threading and Turbo Boost disabled, will work with four cores at 2.20GHz. For audio purposes, therefore, what would be the difference of an Intel J5005, which has four physical cores working at 1.50GHz and only 10w of TDP? What would be so significant compared to an Intel N3700 with four physical cores working at 1.60Hz and only 6w of TDP? Only in the 8th generation of processors is the Core i3 now have four physical cores. For more RAM, USB cards, M.2 connections are good, I have no doubt that processors like the J5005 are still the fastest part of the entire computer, and that with everything off, expensive processors with expensive motherboards are underutilized. Despite this, the exceptions are very important.


The first exception I referred to is the Xeon line. These processors have a completely different operation, but more importantly, server motherboards have a much higher, more robust construction with very high precision components, and this greatly benefits the performance of the computer in terms of music reproduction. So, for certain applications, I just find interesting to leave the motherboards with embedded processors to go to the Xeon line. The second exception I mentioned above is the processor cache. Tests carried out by several users are unison in the sense that a large cache brings very significant benefits to the quality of the audio, and that is one of the characteristics of greater responsibility in the approximation of the analog audio. But what is this cache? 6MB? 8MB? Something to conclude, then, that a Core i3-8300, with its 8MB cache, is superior to a J5005, with its 4MB cache? Not at all! I mean something on the order of 25MB, 30MB, up to 60MB cache. Using a 6 or 8MB processor will not even tickle an audio file, which allows me to come to the conclusion that, again, if it's not to mount a PC with an Intel Xeon, it's even better to use a motherboard with an Intel J1900, N3700, N3710, N3160, J4105 or J5005, because they will allow to build a computer with consumption in the order of 20w, as it's what I have here, that consumes something between 20 and 25w, when in reproduction, and this with a SOtM USB card and a linear power supply that I believe is responsible for at least 5w of that total.


The third and more important exception, in my opinion, is related to a Single-PC or Dual-PC setup. When using the Single-PC or Dual-PC configuration, there may be a greater demand for processing, bitstream, latency, and so it may be interesting to have a more powerful computer being used as Control-PC or as Single-PC. Here, using (for now) a computer with an Asrock J1900-ITX motherboard, 16GB of DDR3 RAM, a 1TB SSD, and a dedicated USB card, I could play 192/24 with JPLAY v. 6.2 at 700Hz and 0.01s without interruptions in Single-PC mode, and I can now play 192/24 at 1000Hz also without interruptions with v. 7.0. As it's now the Audio-PC, it's still more than enough to play 192/24, and I think it wouldn't have problems even with DSD256. However, in this case, the Control-PC will import more, so I think that for DSD playback, in both Single-PC mode and Dual-PC mode, at least one computer needs to be powerful (I repeat, not for 192/24) and preferably an Intel Xeon (because I really don't see an advantage in using a Core i5 or i7 if it's to disable various features in the BIOS).


What we can observe, in the end, is that building a dedicated computer, after all these observations, may seem extremely complex, but it isn't. But it's not cheap either. The fact is that for certain applications, it's much smarter to direct the investment to particular components, such as a dedicated USB card and/or a dedicated LAN card, and the return on audio quality will be much more significant than using a Core i3- 8300 compared to a J5005. The issue is not performance, benchmark, but process exclusivity, low heat generation, low latency, low jitter, minimum use of onboard controllers and low power consumption.


To summarize: if you're going to use a Single-PC configuration and will not use an Intel Xeon, buy a motherboard with an embedded processor and direct your investment in the amount of RAM, storage capacity (1TB SSD, at least), linear power supply and dedicated USB board. No need for Core i3, i5 or i7. If you're going to use a Dual-PC setup, the most perfect would be to use both Intel Xeon-based computers, but if that's not possible, I also don't see a need for anything other than an embedded processor, keeping the investment focus on the USB card, on te dedicated network cards and linear power supplies. And, for those who would like to know my opinion, I say: yes, I think the best USB and network cards in existence today are the JCAT FEMTO. Better than SOtM and much better than PPA. Currently, I have a SOtM tx-USBexp, but I intend to buy a JCAT as soon as possible, because I don't consider SOtM a reliable brand in terms of effective troubleshooting, and have literally abandoned the evolution of USB cards. This differentiates JCAT from other brands.


In the next post I'll write about the software.

#43729 Kazoo no tidal?

Posted by Marcin_gps on 25 June 2018 - 08:11 AM

Hi Marcin,


Is there a chance we have Tidal & Qobuz supported by Kazoo with JplayStreamer one day ?

Like we can see it on Kazoo with Linn network player ?

For me it is only the last things Jplay needed to be the best of all  ;)

There will be a solution soon. We are getting close to the biggest announcement in the history of JPLAY.
