I've check the Sonos system, I was very tempted BUT they do not support higher sampling rate than 48khz.
When you see all music companies going on-line with Hi-Res downloadable 96khz/24bit albums you wonder it is not worth waiting for an updated version.
just my 2c

I personnally do not want to be forced to have my pc open when I play music, so SBs for me....
