Hey, I just had this thread a week ago!

Dead as a doornail, I say. With that said, I have seen some guys on here that still have multi-disc player arrays, they might not agree.
Especially since they then added a DAC back in 2006 that was all the rage. They probably think they are still state of the art, no need to take advantage of the newer technology.
That's the thing with digital, it's ever evolving, and the difference between the sound of audio files from the more advanced DAC set ups can be remarkably different.
State of the art in 2007 is now about the same as what you get in your $200 BluRay player. The only difference to me, is when you get to the truly high end DAC's by companies such as ARC et all, where the output stage is so much better than anything you get in a run of the mill DAC, that it still sounds better.
Disc players are dead.
