Re: Apple TV and iPod touch
sooloos? all that is is a touch screen to a itunes look alike screen. (check out version 8 of itunes. same screen with more additional configurations plus you also get the Genius sidebar). i have convinced a couple of people to go with a music server setup like mine over purchasing qsonix or sooloos systems. sooloos and others including an itunes server sound like crap without going thru an external dac and for the best sound using a jitter reduction device before the dac.
my setups have included multi-terabytes of NAS configured as raid 5, backup storage, mac mini, jitter device, external dac, good quality cables, apple tv's or airport express devices or even separate mac minis (used older g4 types is all you need) depending on if you need multi source or not, and an ipod touch to control from anywhere in your home, all for 1/3 the price of a standard sooloos configuration. a similar sooloos setup with the same amount of NAS storage, jitter device and the same external dac, would cost in the low $20k range.
if you do it correctly, you can have a music server sound every bit as good as an audiophile cd player.
