Agiaccio......I don't believe that the above posters are giving Sonos the kudo's they deserve. Sonos provides an excellent platform for your computer based music. It's relatively inexpensive, it's easy to use and install, product support is excellent, and on and on, just can't say enough positive about the product itself....As to the quality, good as purchased, but not high end, however, you can take Sonos to just about any level you want utilizing dac's, reclockers etc. Sonos run through a good system and a $500 dac provides some very nice sounds.
