Why CD players will never be dead
Rrm - use XLD for ripping to Mac - its free:http://tmkk.pv.land.to/xld/index_e.htmlYou must be on line to rip using Accurate-Rip for comparison. iTunes is not good enough.I would recommend to rip CD's to AIFF if you want tags and album art to be p... 
Why CD players will never be dead
I still buy CD's mostly from Amazon, but I rip every one of them and playback using Mac and Amarra. CD players are not even close. I dont do computer audio for the convenience, I do it for the sound quality. I modded CD players and transport for c... 
WAV vs. FLAC vs. AIFF
Al - Just another datapoint telling us that the CPU execution is having an effect on sound quality.This is why I recommend only Mac, and only Amarra 2.3.x. This combo is simply killer. My PCs are not even close.There are still SQ obstacles even wi... 
WAV vs. FLAC vs. AIFF
"The noise transients I am envisioning are associated with the abrupt SWITCHING of cpu clock rate, and in some cases voltage as well, that unless disabled by the user will occur as processing tasks intermittently start and stop."Huh? There are cer...

EDorr - are you using a USB interface? What player S/W? Are you using a Preamp? What ripper did you use?All of these must be optimized in order to get stellar results, and to hear these differencees easily.Steve N.Empirical Audio

"The idea that the FLAC decoder produces wrong numbers is just not credible. People have repeatedly shown that the compression/decompression algorithms works."Yes they have, but only staticly, never real-time.Electrical noise in the PC is not the ...

""Malfunction"? Are you saying that the 16/24 bit data for each sample is incorrect? That the data that comes out of a flac decode is different that the wav data?"Yes, I believe its incorrect when the decoding is done on-the-fly.Steve N.

Mapman - Even though I sell only USB interfaces, and I'm able to achieve good performance, I believe that the ultimate solution that takes the computer out of the equation is networked audio streaming.There are several proprietary networked system...

I believe the run-time problems cause the FLAC CODEC to malfunction.I do not believe it has anything to do with async USB. My customers told me that this happens even with my older adaptive USB interface.Steve N.Empirical Audio 
WAV vs. FLAC vs. AIFF
Mapman - that figures. With networked audio, you are less likely to hear differences. Data is just data, not audio data as with USB or Firewire, so the audio stqck is less involved, if at all. Jitter from the computer is also a non-issue with netw... 
WAV vs. FLAC vs. AIFF
Mapman - whether you can hear these differences or not is highly dependent on your system. For instance, if you use an active preamp of any kind, you may not hear a difference. Preamps add a layer of noise, distortion and compression that is signi...

"Do you have enough details on the async drivers to know if process swapping can actually effect the async driver significantly? If there really is a problem there, then improving the clocks in async converters should not be important."Improving t...

DTC - I believe the problem is latency and interference, not CPU usage. When the core audio stack interferes with smooth execution of the FLAC CODEC, this is where the problems start.Has nothing to do with async USB converter and delivering data t... 
WAV vs. FLAC vs. AIFF
Okay, here's my hypothesis:When using networked servers, such as Sonos and Logitech, the decoding processes of FLAC and ALAC have plenty of time to execute because the other processes are not real-time. This is because the networked stream is pack... 
PS Audio DL3 USB Question/Streaming
If its Async USB, the protocol may break if any latency is added by the extender.Steve N.Empirical Audio
