Music Servers & Sonos. XiVA Music M8, W4S ?

OK
Getting a Sonos.
Majority of my music is on my Apple MacBook & IPhone.
I do not want to use my Laptop as my music server.
I do not just want to use an IPhone dock or anything like that.

I am looking for something that will be easy and idiot proof!
Something where I can add CD's easily and will easily sync with my iTunes.
Something which will work well with Sonos and its interface.

I will also use a DAC and hook up whatever I get to my stereo.

So far I have been most intrigued with the Wyred for Sound Music Server (coming out) and also the Xiva MusicM8.

Does anyone have any suggestions of other systems I look at?

Thanks!
