About a year ago I replied to the TT3 thread with some measurements comparing CPU utilisation in the Touch at 16/44 and 24/96 with and without server-side FLAC decoding. For my tests, I used a wired Ethernet connection. CPU utilisation was measured simply by connecting via SSH and running 'top'
I don't have the exact figures to hand, but IIRC at 16/44 the difference was something like 10% (via FLAC) vs. 30% (PCM to SBT), and at 24/96 it was (55-65% vs >90%). I couldn't detect any beneficial effect of streaming PCM, but this did establish that the theory supporting improved SQ with at least this component of TT3 mods was a bust. Unsuprisingly nobody could think of a reason why more CPU utilisation would be better, especially since the theory was based on the opposite being true. Suprising that nobody bothered to check before, especially as it was so easy to do. Ah.. here we go.. found my tests on a different board - http://theartofsound.net/forum/showthread.php?t=15594&highlight=Touch+CPU&page=8 Archimango - excellent work on the tests BTW. I also have a Emu 0404 USB, and have long been telling people what a cracking interface it is, especially for the money!. Your figures do show it to be a very transparent device for A/D. You have inspired me to do some testing of my own to optimise the noise performance of my system.
