Yes, even if. And of course, there is no real reason to use 192khz, since there is no information there. I"ll agree that 88.2 or 94 x 24 can be better than 44.1/16, but only "can be" not "is". The detailed data rates for RedBook (uncompressed PCM, aka 44.1/16) are 172 Kbytes/second. So it is easy to see that to make CD audio, you need at about 1.5 Megabits per second. If you go to 88.2kHz, you double it to ~3 megabits/second. Go to /24 and multiply by 1.5, to ~4.5 megabits/sec. Raw, flac will compress RedBook by about 50%, taking you back to ~2.2 mbs. Since 802.11g delivers more than 50mbs, you have tons of room, and if you insist, can double it again, since twice ~2.2 is still ~4.5. The numbers are slightly bigger if you change from 172.4 to 192kHz, but not enough to make a serious difference. The bigger issue question is "is there any signal up there" and so far, for nearly all studied cases, the answer is "no". A fair amount of even 88.2 kHz recordings are just made from the 44.1 masters, so there is not much, if any, signal above 22.1 kHz. The actual bits may be different, as recordings sold to audiophiles tend to suffer less from Loudness Wars, and may be mastered more carefully. But its not like the expensive professional microphones out there have any ability to capture signals much over 20kHz. One also has to understand the realities of making a new product in the SlimDevices space. The Touch was released to manufacturing last Summer. Its design was finalized before the 11n spec was finalized. For a mass market product like all of the SqueezeBoxen, its not really a matter of when the "spec" part is finished, but rather its when do the chip makers ramp up production so that the support chips are in large enough volume to be inexpensive. Its one thing for early adopter geeks to want to by the first 802.11n router, its another thing for LogiTech to order half a million chips.
