RE: JPLAY Responds

I am perplexed by this statement:

"We at JPLAY believe the old rule 'simpler is better' should not be ignored for computer audio—to the contrary: We believe that the less work a computer has to do the better it will serve as a digital audio transport."

From what I see, the Kernel Streaming "engine" seems to be doing a good amount of "work" when the computer is set to their recommendations with "DirectLink" "buffer" size. "Simple" would be using a decent buffer and just let the hardware negotiate rather than using the CPU to do all the timing, especially with modern asynch DACs IMO.

Also, this:
"Sure, we don’t have all the 'technical measurements' we would like: The simple fact is, while there are plenty of DAC measurements regarding jitter, when it comes to using a computer as a digital transport, there simply aren’t any! Nobody has quite figured out how to measure ‘computer jitter’ (or 'computer noise'), which others propose is the "real" cause of the sonic differences in software and/or hardware."

Firstly, not only do they not have "all the technical measurements we would like", admittedly they simply don't appear to have "any" to support the assertion that their theory is true. Assuming for a moment JPLAY did make a difference, how then would they even know that *timing* was to blame rather than say a Windows/ASIO/WASAPI/DirectSound bug they've circumvented? This also leads to a very inconvenient situation where one has to ask by what means they engineered the audio engine - not just ONE, but as it stands FOUR choices!
