Sure, and I've been sharing my knowledge since the beginning in 2011. But please note that apart this being a super exciting hobby, it is also a business and I have to earn money to feed my family.

Thanks for your assurance Marcin. I certainly find your guides very helpful. They improve sound quality as claimed and are easy to follow for those like me with limited technical knowledge.

JPLAYmini preloads full tracks before playback even starts. Plus, there is less network activity as the files are loaded into memory directly from a hard drive vs. through a server in JPLAYStreamer. 

a question, witn jplaystreamer is the file load in memory before playing?

Yes, but the memory buffer is smaller. JPLAYmini loads a full track into memory before playback starts.

I'm using JPLAYstreamer with MinimServer on a single PC. Everything is running directly from RAM (I'm using RAMdisk) and the files are stored on a 500GB SSD. I don't know why, I've always used system latency setted in 15.6ms. Recently, I switched to 0.5ms. Besides that, I changed the Ayre QB-9 buffer size to the minimum (1ms) and tried JPLAY using 700Hz/0.01s. I also use a SOtM tx-USBexp, and intends to buy, in future, the JCAT Femto USB.

 

All files up to 96/24 are played normaly, but,at the last 10s, the playback stops. 192/24 files doesn't work. Anybody can help me?

What if you load from a disk not from a ram disk? Please check if all power saving features are disabled for drives, usb controllers and network adapters.

I use RAMdisk to send the entire Windows partition to RAM, first, beause latency is much lower than SSD (random access is 4 to 8 times faster - https://www.htforum....3/#post-8272852), second, because the sound quality is much better than use Windows directly from SSD and, third, to use SSD exclusively to transfer music files during usage. Once Windows was loaded to RAM, nothing more is readed in the SSD, except music files, which, for me, sounds better than the "normal" usage.

 

Concerning to power saving features, everything is disabled by the Audiophile Optimizer itself. Another interesting thing is that, even though not using the Ayre ASIO driver, changing the latency to the minimum on its own interface was critical to getting the 700Hz/0.01s operation.

 

Yesterday, after trying many and many times, I was able to play 192/24 files and whole discs in 44/16. However, sometimes reproduction stopped without any explanation. After I posted here, I did not change any other settings, but even then, the songs played, although not without problems. Set JPLAY to 700Hz/0.01s and OS latency to 0.5ms sounds much better, with more natural and realistic sound, with better spatiality, richer harmonics, and I'll keep trying.

Guys, some news.

 

I tried every kind of configuration to play successfully every bitrate, from 44/16 to 192/24, using 700Hz/0.01s in JPLAYSettings. Nothing changed. However, I noticed that only WAV 192/24 files doens't plays well. When I converted some files to FLAC, JPLAYstreamer started to work at 192/24. I cannot find an explanation for this, but, if I can help with anything, that's a tip. As not everything is perfect, I still have some problems of interruption in the transition between one track and another. I have no idea what to do to solve it.

 

Best regards, Felipe.

 

PS.: I use JPLAYstreamer + MinimServer + FFmpeg in a single PC with RAMdisk. My computer: Asrock Q1900-ITX, 16GB RAM DDR3 1333MHz, 500GB Samsung 750Evo SSD, DIY linear power supply, SOtM tx-USBexp, Audiophile Optimizer, Audiopheeling SATA Statement cable. My DAC: Ayre QB-9 192/24. My USB cable: Curious Cable.

You did not share what OS you are using. If it is WS 2012 R2 then you should not have any problems. With WS 2016 and Windows 10 it is frustrating to make it work. Just you thought you've made it work and next day interruptions appears.

Maybe, that's the cause. I'm using Windows Server 2016...

 

So, is it like a "chronic" problem of Server 2016?

Unless you have 3 pc setup. Server, Control and Audio. In that scenario it is working. But I recommend, Control PC to be in WS 2012 R2.

I'm starting to use and test JPLAY in dual PC configuration. The dedicated computer that I refered above is, now, the Audio PC, and the control PC is a notebook with Core i7, 16GB DDR4, 2TB HD and 120GB SSD, nothing dedicated, neither Windows. Even so, the performance level is appreciably better than use JPLAY in single PC configuration. I created a DHCP server to connect the notebook directly to the Audio PC and it's work good, with better results than the use of the router between the computers, with no dedicated cables and no dedicated power supply. I chose this configuration because, in future, is probably the method I'll use to connect both computers, with less cables, unless anybody convince me that using a router is better for the result. Any opinion? Can the additional DHCP server process lead to loss? More than two cables, a switch with a doubtful power supply? Two JCAT cards attached directly to each other would not be much better? In other words, would the damage of an additional process on the Control PC be worse than two cables and a switch? I think of something like this, but I do not know if it waives the use of the DHCP server:

 

scheme3.jpg

 

For now, even though I cannot use 700Hz/0.01s in JPLAY, using 350Hz/0.01s bring me the best sound I've already heard in my system. My doubt is: in dual PC configuration, does the JPLAYSettings of the Control PC matter, or just the Audio PC configuration?

 

Thanks guys!

Direct connection is best unless you have sth like M12 SWITCH GOLD. 

You don't need to run a DHCP server on control PC, both PCs can be configured to static IPs.

First, try both with WS 2016. If you don't get a stable connection at 700Hz/0.01s - run Control PC with WS 2012 R2.

Thanks Bernie! Actually, what I want to know if about the parameters of the Control-PC itself. In dual PC configuration, the parameters displayed on JPLAYSettings are those that I configured when I used single-PC configuration. I simply changed the Audio PC from "This computer" to the computer that's in my network. However, it's still possible to change the parameters of the Control PC individually. In this case, does it matters? Or just the Audio PC parameters, that are shown in Control PC??

 

Thanks!

Thanks Bernie! Actually, what I want to know if about the parameters of the Control-PC itself. In dual PC configuration, the parameters displayed on JPLAYSettings are those that I configured when I used single-PC configuration. I simply changed the Audio PC from "This computer" to the computer that's in my network. However, it's still possible to change the parameters of the Control PC individually. In this case, does it matters? Or just the Audio PC parameters, that are shown in Control PC??

 

Thanks!

 

I'm not sure which parameters you're referring to for the Control-PC in a dual PC setup. Could you provide a bit more detail please.


Control Point: Apple iPad (9th gen), 64Gb storage, 3Gb RAM, JPLAY for iOS 1.0.17; Samsung Galaxy Tab S6 Lite, 128Gb storage, 4Gb RAM, Bubble UPnP 4.3.3.1; Dell Inspiron 15 5510 laptop (Windows 11 Professional (x64) Version 22H2 (build 22621.3007), Intel Core i7-11390H, 2.93 GHz, 512Gb KIOXIA M2 PCIe NVMe (RAID) SSD, 16Gb DDR4 3200 MHz RAM), Upplay 1.7.1.

Control and Audio-PCs: Asus Mini PC PN60, Intel Core i5 8250U 1.6 GHz, 250Gb Kingston A2000 M2 NVMe SSD and 8Gb DDR4 2400 MHz RAM.

OS: Windows Server 2019 (Standard Edition) in highly optimized Desktop mode, command prompt shell for initial setup after which Control and Audio-PCs run headless (monitor, keyboard and mouse disconnected).
Optimization: Audiophile Optimizer 3.0, ES151 as Local Service via TrustedClean 3.1b-server on RAM Disk on Control and Audio-PCs (TC settings used are detailed in in the TC3.1 guide below). Process Lasso Server Edition 14.0.1.10, additional Windows processes/services stopped via registry editor, task manager and a modified CAD DSK script. For the full optimization procedure see my Guide for Optimizing WS2019 in a Dual or Single PC JPLAY Femto-Based System (revised 5 July 2023).

In dual PC setup, the parameters you see in JPLAY settings panel on control PC are for audio PC. You can change them and they will be effective on audio PC. There are no parameters for control PC.

That's what I wanted to know: if there's a parameter for Control-PC. Thanks guys!

 

Yesterday I changed the network configuration between both computers. I stopped the DHCP server (one process less) and configurated the computers to use just an IP and a subnet mask. Control-PC uses 192.169.0.1 and Audio-PC uses 192.169.0.2. The DHCP server process didn't harmed the audio quality. However, e tried a subnet mask that only allows two hosts, decreases the size of the broadcast (I just need two fixed IPs) and has 22 leading bits (255.255.255.252). The audio quality improved a lot!

 

Thanks guys! Let's keep trying to get the JPLAY always better.
