Hi Marcin& Josef,
I have problem initiating playback with DAC link:700Hz only with JPLAYstreamer. I tested 3 scenarios and here is how it goes:

All settings are DAC link: 700Hz, PC buffer: 10s
Scenario 1: With JPLAYmini, it works perfectly. No dropouts during playback.
Scenario 2: With JPLAYstreamer+MinimServer, most files wouldn't play. However, some files with higher sample rate (larger than 44.1) plays perfectly.
Scenario 3: Same setting to Scenario 2. I tried lowering DAC link first (to 350 and below). I start the playback, and then pause, then change DAC link to 700, and then resume playback. Now It plays perfectly without dropouts.

I think it is some issue "initiating" playback with higher DAC link. How can I solve this problem? Thanks!

DacLink 700hz needs lower PCbuffer, try 0,01s instead. Also usb driver needs to be set to minimal latency and Asio buffer 64 or 128mb.

And to add what Pachanko said, not all drivers support such low buffers even if it works for a while there is no guarantee of stable playback

I personnally love 1hz/10s with max buffer asio and extra safe latency on usb control pannel. And clock set to 3 with JPLAYStreamer and Asset UPnP :) Very analog sounding

I remember reading on this forum that changing the DAC link on-the-fly sometimes has no effect unless the JPLAY service is restarted. So possibly you were still on 350 rather than 700.

For me Asset is to smooth - doesn't offer the level of articulation and microdynamics as MinimServer although it seems pleasant at first. 

I tend to go minimum buffers, DAC Link 700Hz/0.01s, Clock 0 these days. After months of experimenting I realized this is the only way to get closer to music.

Changing DAC Link on the fly is not possible. One has to stop playback first :) Restarting JPLAYService is not required

In my system minimserver is too smooth and sound dull compared to Asset. Are you using 64mb buffer in asio control panel?

Minimum Latency.

Asio Buffer Size at 64 samples, but it has real effect for ASIO only.

I think 700hz needs cpu set at fullspeed right?

It doesn't depend just on CPU performance. DAC's driver performance is more important - some can handle 700Hz and some not. Even if same DAC is used with different driver versions results vary.

What cpu speed did you use Marcin?

Are you still running DualPC ? I supposed you have 2gb of ram on AudioPC and 8gb on control?

hi Marcin,
 
You are right, I was not thorough enough to re-read the post I mentioned. It is post #15 of the thread “700Hz/0.01sec ULTRAstream stable after Windows Update”. There, Dev mentions:
 
“HQPlayer may be still using the cached settings of 40Hz. Try closing HQplayer and re-open to see if it still works with 700Hz.”
 
So in my case it was an HQP/cache thing rather than a JPLAY thing.

Got very nice results with MinimServer and daclink set to 170hz/0,01s 700hz seems to be to much analytical. Thank you Marcin for the tips.

Hibernate mode in single pc works great with MinimServer :)

SinglePC at the moment, but planning to use dualPC soon again

I'm running singlepc too with Qnap Nas and hibernate on. After a long comparative session i can confirm that Minimserver is better than Asset with minimal latency value and clock set to 0. Very airy sound with a huge soundstage. I have set my jplay settings to 350hz which is a great value. Marcin, can you tell me what is the equivalent of 350hz with the old version of Jplay? US=40?
