All this gunk about inputting to PC. If you are going to buy a new sound system, think about buying a CD burner to go with it. I use a Pioneer CDR509, had it for over 4 years now. I never had a duff burn. You can connect it to your pre amp (receiver) using coax digital, optical digital, analogue RCA sockets, and it will record which ever source is selected on your pre amp. The only slight downside is that you need to buy "Music" or "Audio" blank cd's, the cheep ones for the PC won't work. However they are normally only a few pence more.
There is a pro audio company in the UK that produces a dervivative of this deck as a Mastering CD writer for if you had recorded yourself or your band.
Hope that gives you something else to consider (or confuse).
