#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,

Marcin

#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

#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.

#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.

#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.

#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

#45566 JPLAY FEMTO - patches

Posted by Marcin_gps on 10 November 2018 - 03:37 PM

Download latest JPLAY FEMTO

 

JPLAY FEMTO 7D patch

 

 

Changelog:

Fix ALAC and some 32-bit WAV tracks not playing (thanks to our Japanese fans for reporting!)

- Fix some tracks not playing due to large metadata

Miscellaneous stability improvements

- Add support for DoP DSD256 via Kernel Streaming if DAC is capable of 700+kHz
- Add error code and troubleshooting tips if online activation fails

- Add support for internet radio (see below article how to use)

 

How to to make JPLAY FEMTO play internet radio:

 

Let's say our music library is on D:\Music.

Then make a folder D:\Music\radio (name can be anything) and in it create subfolder for each station you want to listen to.

For example to listen to SomaFM Groove Salad make folder C:\Music\radio\Groove Salad.

Then create a text file with extension .radio (let's call it GrooveSalad.radio) and put just URL of internet station: in there, e.g. for Groove Salad: http://ice1.somafm.c...vesalad-256-mp3

You can optionally put an image (any name, e.g. cover.jpg or groovesalad.png) in the folder so you also have nice art shown on your tablet/phone.

Repeat process of creating additional folders under D:\Music\radio and making .radio file for each station you want to use.

 

 

JPLAY FEMTO 7C patch

 

Changelog:

- Add support for 'Pause' for DSD tracks.

- Fix 'loop' at end of playback in Hibernate + SinglePC mode

- Fix Japanese/Chinese or other Unicode characters preventing track from being shown: Track metadata now must be in valid UTF8 format to be accepted.

- Fix issue where playback via BubbleUPnP does not work and two appear not to communicate. It happens after Femto update when BubbleUPnP still has a cached copy of 'old' library.

- Fix 'tick' near start for MP3 tracks

- JPLAYDriver & JPLAYmini: no updates.

 

When installing an update of JPLAY FEMTO please clear the cache of your Control Point app!

For BubbleUPnP, this means:

1. Clear Playlist

2. Select 'Local Renderer' then select 'JPLAY FEMTO' again

 

Other Control Points may have different caching strategies - If in doubt just restart phone/tablet.

 

 

JPLAY FEMTO 7B patch

 

 

Changelog: 

- Fixed bug with Xtream engine causing distortion or no playback at all

- Fixed Classic engine clicks/pops on older UAC1 DACs (users with UAC1 DACs should set UAC1USB entry in regedit to 1 under Computer\\HKEY_LOCAL_MACHINE\Software\JPLAY7 key)

 

JPLAY FEMTO 7A patch

 

Changelog: 

 

- Added support for music library on multiple disks to more control points (mConnect, Glider etc)

- Deduce music format if control point/server does not provide info (mConnect, Synology etc). (This was causing incorrect playback for DSD/HiRez)

- Fix issue where tracks don’t appear because of some (mainly Asian Unicode) characters

- Fix Hibernate not working for ASIO + ULTRAStream combination

- Fix JPLAY Driver not playing when using ULTRAStream
- In JPLAY dual PC setup it is no longer needed to have an audio device on ControlPC for JPLAYSettings panel to show up

- Other smaller bugfixes

 

Notes: If you experienced any of the above issues, please download JPLAY FEMTO again and reinstall. If you already activated JPLAY FEMTO, there is no need to activate again. After updating you will see the current version in the bottom left corner of JPLAY Settings panel.  

 

If you didn't experience any of the mentioned issues, there is no need to update. 

 

 

Regards, 

Marcin

#45476 RAMdisk with Windows Server 2016 - 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.

Here is a working video:

#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.

#43974 How to run Dual PC setup and achieve KS/Ultrastream/700/0.01s GUIDE

Posted by taxman2 on 25 July 2018 - 02:27 PM

Finally I’ve found time to write this guide. I presume most of you are advanced users and will not go through details of how to install your OS. If you don’t understand certain terminology just google it.

I am writing this based on my personal experience in dual pc setup. It took me two years to set it up properly without interruption of playback at KS/Ultrastream/700/0.01seconds.

My setup is:

 

Audio PC:

It is a mini PC fanless, aluminum body, Skylake 14nm CPU Intel Core i3 6100U 2 cores 4 threads 2.3GHz 3MB cache TDP 15W, 4GB RAM; Powered by 100W/12V/5.5A Ultra Low Noise LPS.

Window Server 2016 Standard Core, installed drivers and programs: Holo Audio Driver v.4.43 (for SU-1), RENESAS USB3 Host Driver 30230 (JCat USB Card), Intel® Ethernet Server Adapter I350 for (Femto Net Card), JPlay, Process Lasso Pro, Fidelizer Pro 8.2, AO 2.2

Added hardware: JCat (USB & Net) cards, JCat USB Isolator. Powered by 100W/5V/6A Ultra Low Noise LPS.

 

Control PC:

Mini PC fanless, aluminium body, Skylake 14nm CPU Intel Core i5 6200U 2 cores 4 threads 2.3GHz up to 2.8GHz 3MB cache TDP 15W, 16GB RAM; Powered by 100W/12V/5.5A Ultra Low Noise LPS.

Windows Server 2012 R2 Standard core (don't try WS 2016 - you will not succeed), installed programs: JPlay, Process Lasso Pro, Fidelizer Pro 8.2, AO 2.2, MinimServer, Java 32 & 64bit, Bubble UPNp Server; Intel® Ethernet Server Adapter I350 for (Femto Net Card).

Added hardware: JCat Net Card. Powered by 100W/5V/6A Ultra Low Noise LPS.

I will presume that you have no Process Lasso Pro, Fidelizer Pro and AO.

Both control and audio pc must be dedicated audio pc's.

 

 Audio PC setup:

After installing Windows Server 2016 core, update from sconfig settings all recommended updates only. Don’t instal Graphic driver at all. Just use the default one. Install audio driver. Reboot and go to audio driver settings - Uncheck Asio safe and set the smallest latency available (in my case it is 8 samples). If you have JCat Net Card, follow Marcin’s instructions). If not - install the latest ethernet adapter driver for your netcard. If it is Realtek install the driver utility (upon running it you get access to Realtek ethernet advanced settings. Install JPlay. Reboot. Run sconfig and change your ethernet connection IP to static and whatever IP you choose. Have in mind that your net card advanced settings must be the same on audio and control pc.

The following advanced settings are for Realtek net card; First uncheck safe power.

 

ARP Offload - disabled

Auto Disable Gigabit - disabled

Energy Efficient Ethernet - disabled

Flow Control - disabled

Green Ethernet - disabled

Interrupt Moderation - disabled

IPv4 Checksum Offload - disabled

Jumbo Frame - disabled

Large Send Offload v2 (IPv4) - disabled

Large Send Offload v2 (IPv6) - disabled

Maximum Number of RSS Queues - 4

Network Address - empty

NS Offload - disabled

Priority & VLAN - disabled

Receive Buffers - 1

Receive Side Scaling - enabled

Shutdown Wake on LAN - disabled

Speed & Duplex - on max (1GB dual)

TCP Checksum Offload (IPv4) - disabled

TCP Checksum Offload (IPv6) - disabled

Transmit Buffers - 1

UDP Checksum Offload (IPv4) - enabled

UDP Checksum Offload (IPv6) - disabled

Wake on Magic Packet - disabled

Wake on pattern match - disabled

WOL & Shutdown Link Speed - disabled

 

Control PC setup:

Install Windows Server 2012 R2 GUI. Update from sconfig settings all recommended updates only. Do not install Graphic driver (use the default).

Install Java 32 & 64bit versions.Install JPlay. Reboot. Update Realtek net driver. Follow AO guide how to setup the ethernet properties. Uncheck everything except Internet Protocol Version 4(TCP/IPv4) and do whatever is in the guide. Set up your static IP. Do exactly the same advanced settings as on audio pc. Follow JPlay manual and start JPlay settings. Your control and audio pc are now connected. Install MinimServer. Set up MinimServer (follow JPlay manual). Install Bubble UPnP Server. Follow first 3 steps of Marcin's post: http://jplay.eu/ml_p...-sound-quality/

 

When everything's been setup open JPlay settings and set KS/Ultrastream/700/0.01s. Now you should be able to play w/o interruptions. It also depends where your library is, (SSD or HDD). If your library is on HDD the response is slower and might not be able to play at 700/0.01. In my case (my library is on 4 HDD connected via USB to control pc) and I could play only wav and flac files 44.1/16 at 700/0.01. For all the rest I use 350/0.01. For hires files to play you need an internal sata3 SSD. You could always add a third pc for your library and connect it via ethernet cable to control pc. The 3 pc setup is a guarantee for successful playback w/o interruptions.

Of course it helps a lot and SQ is amazing if you have Process Lasso Pro, Fidelizer Pro, AO. 2.20 and JCat Femto (USB & Net) cards.

Now convert to core. Don't forget to copy avicap32.dll and msvfw32.dll in your Windows\System32 folder. On start up you must have MinimServer running. Manually assign it to run on startup. You could do it using a script. Or you could use Fidelizer Pro to run it as a media player application.

After the library has been loaded you can Open Kazoo or whatever control point application from different phone or computer and play.

Of course you must suspend power on all usb controllers, net cards and whatever you find applicable. AO could take care of that too. Preferably make pc's headless, just turn them on and off from power button.

#36808 HySolid HiRez Music Player

Posted by AudioDoc on 04 July 2016 - 12:18 PM

In order to get HYSOLID player working using JPlay as the ASIO, here are the steps.

Run all the following from GUI.

1.       Reset AO to enable all services.

2.       Uninstall Fidelizer

3.       Uninstall JPlay

4.       Install HYSOLID

5.       Change the two HYSOLID services to run as the logged on user instead of Local System

6.       Install JPlay

7.       Open the HYSOLID ASIO Panel, highlight JPlay ASIO, then click Start (nothing will be displayed; this will tell the program to use JPlay ASIO)

8.       Open the HYSOLID Tool and setup the drive for the music (http://www.hysolid.com/howto.html)

9.       After a successful installation, launch the app on the iPad, iPhone etc.

10.   Select JPlay ASIO

11.   Play music to confirm that JPlay ASIO is working

12.   Install Fidelizer (if it is used in the configuration)

13.   Play music, to confirm that the program is still functional with the JPlay ASIO driver.

14.   Run AO either in GUI or switch to core, if that is the preference.

15.   Before switching to core Fidelizer needs to be installed and configured, in my experience when you get into core the logon will revert to Local System if Fidelizer was not installed and configured before switching to core mode.
