I also check in on Computer Audiofile every now and then. Just like the Outlaw Saloon, the site owner and the folks that frequent there welcome everyone and are very willing to help and share their insights. While my computer-to-HT setup is very modest, the USB connection on the 990 has come in handy; my kids routinely connect their macbooks for iTunes playback. All their music is compressed MP3s and ACC so the USB capabilities on the 990 have not been an issue. I currently have five year old PC/Windows setup using a linksys music bridge connected to one of the 990's optical inputs. However, I may see the light (or go to the dark side depending upon your point of view) and buy a Mac. What kind of setup are you using?
