Music Servers & Sonos. XiVA Music M8, W4S ?

As for a NAS I'd recommend the Netgear RNDU2120 or RND2210 the 2120 has faster processor and dual gigabit ports among other features but the 2210 would also be fine and is a bit cheaper. Both are very easy to setup..pretty much plug and play, read the directions :-) Both are 2tb units, they can be setup as Raid 1, Raid one is a mirror.. it reduces the storage space from 2tb to 1tb but what ever you copy to the NAS is automatically duplicated on the other drive, FYI a 1Tb drive will hold about 3000 cd's

Rega Dac is a nice unit, haven't heard, it but it's gotten lots of good press. Other nice Dac at that price is the W4S Dac 1.

No you won't rip the music twice. In iTunes you pick where iTunes looks for it's "library" you just point iTunes to the NAS. When you rip (a wired connection is best for this) you will be ripping to the NAS not to the HD in the Mac. When you want to put music on iDevices you just hook them up to the Mac/or Mac Book and it's the same as if the files were on the computer. You can also set iTunes to copy music to the idevice in mp3 format so as not to use up all the space on the idevice. You will of course want to rip your CD's as ALAC files (Apple Lossless) this is Apples version of FLAC, these are Lossless codec's (cd quality, mp3 is not) you could also rip to AIFF ( this is Apples version of a WAV file) but Sonos doesn't work as well with AIFF files and ALAC does sound pretty much the same ( I can't hear any difference, some claim they can)

Thanks!
That makes a LOT of sense now.

I still keep thinking the Mach2Mac may be a good option
but in reality it may be more complex than I really need.

Start out with what we've discussed, you can always add more.. The Sonos is the best muti-source, muti-zone system out there.. if you want to go better SQ wise for you main system down the road, there's no reason you can't. Doing it this way will get you going. It will give you hands on experience, and a better understanding of the various options and how they work. Also nothing you might add, short of a multi-kilo buck full blown Meridian Sooloos system will obsolete the Sonos, so you're also not going to end up with anything obsoleted, at least not for a long time.

Erikminer, you are giving great advice! Glad to have you on the gon!

Thanks J...
