I believe it would be crazy to have a computer set-up with all that is involved to have one on a systemI am curious why you think that? A computer source is quite portable and probably easier to set up than a turntable.
I was not at RMAF'14 but the pictures I have seen seem to show more than a few computer or digital server sources with DACs, and a good number of turntables too. IMO, vinyl will be around for awhile because people still enjoy the presentation, and computer audio is definitely NOT a bust, but rather a better method of achieving the same goal as a compact disc...playing music from digital media.
