Sonos Questions

I've been using a Roku Soundbridge for several years but have never been able to get it to successfully play lossless files without constantly rebuffering.I have spent endless hours on the Roku forum site and unsucessfully confering with their alleged support staff and have finally had enough.

The Sonos looks like a good alternative, but I have a few concerns. Other related threads indicate some sonic issues due to jitter problems. I currently use a Proceed DAC with an optical connection to the Soundbridge, and that change from the stock Soundbridge was a big improvement. The Sqeezebox looks like an alternative, but the Sonos interface seems much better (ie something the rest of the family might actually use).

So what's the consensus on sound, assuming that a decent DAC is used?

Second, I have about 2000 CD's so I want to have a commecial ripping service store them for me. Since my computer system is Apple based, I thought ALAC is the way to go. I've also seen threads here that the Buffalo NAS devices can be problematic for Apple users. I need to choose an appropriate NAS device to get this project up and running.

Any guidance would be greatly appreciated.

Thanks and Happy New Year!
