I suspect massive storage devices, perhaps not rotating, and down loads with high resolution will displace cds at some point. Until recently I had no interest in servers as they all sounded like crap. At CES, I heard two that didn't-the Exemplar and the Blue Smoke. I bought an Exemplar and now face the task of loading it with my cds. Since it takes typically 30 minutes to do it right, this is not going to be easy and I am going to retain a sacd player for my 400 sacds and to play cds while I load the server.
