Thanks to all for excellent comments about the issues addressed in this thread, especially DJohnson, Mapman,and Kacz.
To kacz, I think the last sentence of your response may be dead on target for the future of CDP's,and CD's. It depends on the niche market. Maybe,I am wrong but I don't see the buyer of audio systems up to $2000 (without T/T and accessories) wanting to bother with learning the jargon and in and outs of computer audio. They just want good sound, and possibly the bragging rights to friends.
The more sophisticated buyer who has been involved 5 to 10 years in above mid-fi audio and reaches for the inner circle of the best sound possible is the niche buyer for PC audio, even if he has a fair amount of CD's
I am not sure I know enough about current audio marketing to state with certainity what might motivate the high-end buyer to master PC audio and load up on its accessories.
Another issue that has perplexed me, is how the potential and ultimate abandonment of CDP's and CD's will impact a weakened and struggling economy; because, CDP's and CD hardware are a billion dollar a year industry that provides a fair amount of jobs even despite the cost effective automation of production.
The audio store of the past unfortunately is going by way of the buffalo, however, those that remain, that is, survive, will have a hard time paying bills just selling the music of cyber space via PC's with their own speakers, possibly even better than today's junk that sits on IKEA computer tables.
