Great suggestion!
-
Do not know. My experience is with iFi micro iDSD.

JRiver Media Center Now features SoX Resampler

I tried MC22 on a Mac and it pales compared to Audirvana+. Constrained sound, compared to A+ detailed, and wide separation. I've tried its various up samplers, DSD conversion et al. I use A+ with its new DSD128 conversion filter. Am I missing some setting? My DAC is iFi's micro iDSD. -
I use Audirvana+ in its DSD conversion mode. Its sound is superb. Just recently I downloaded the new JRiver MC22. It just does not sound the same. A+ produces a wide, detailed sound with incredible separation. A+ DSD conversion (DSD128) mode even makes MP3s sound quite good. Try it!

I no longer have static. On my side might have been an A+ bug since fixed. iFi replicated the bug though, so there may be more to it.
-
The nano playing DSD files should provide better sound. At least upsample by a large 2x factor.
-
Noticed that too.
-
All good things take effort and time. The potential has been shown, so it's now a question of time to iron up the bugs.

How do we know Direct Mode is working? On A+ top right I see INT. When Direct Mode is set, playback works some of the time (in OS X 10.11.5), but it seems to have an initialization issue as sometimes the error message pops up. When that happens turning Direct Mode off and playing a track, re-setting Direct Mode often works again. But to the question above... how do we know Direct Mode works?
-
Does that mean you have not experienced static with the latest A+ and iFi micro iDSD when playing music with large peaks?
-
Right! Damien needs to look into this and I am sure he will. There's no doubt he is doing a stellar job in providing this sound quality. Kudos!
-
I suggest you check your A+ Preferences > Audio Filters and try upsampling (Power of 2 or max) or conversion to DSD with volume reduction set at None and play a high volume (high peaks) track and see what you get. I get random static more prevalent on the left channel. It seems to go away if I reduce this volume control to -1dB. I would like to know what this volume reduction does. it may mean a signal chop off, or a reduction in dynamic range.
-
Are you using A+ with or without 'volume reduction' and what amount?
-
Yes.
-
Static, impulse noise. At Damien's advice I set the 'volume reduction' to -3dB and it seems to have taken care of that. Damien says that is probably due to clipped waveforms, which now upset the DSD conversion. I noted though that the same static also occurs in upsampled PCM playback, and did not do that before... Re... CPU usage and loud sounding computer fans, I also reduced the processing buffer to a minimum. I understand Damien's approach - theoretically with an 'infinitely' powerful CPU/GPU and 'infinite' memory one would just let the process loose to generate a DSD file as fast as possible for playback. But... typical processors and RAM spaces have limits. Also I see no need to do that if one can relax the processor to a point where the DSD buffer is just large enough to support uninterrupted playback. I suspect this is what the iPhone Onkyo HF Player does as it is running with significantly more limited resources.
