As a guy who once loved 8-track tapes, I have no problem with SACD, VD-A, BluRay, etc.
For audio, I see it as a small market where the TAMS and the HIRRLL will never be available. You can't even buy the BEATLES there.
Those are good formats if you have a collection, but for guys starting out, the best way to go is 'COMPUTER AUDIO' as it will not be dated any time soon. (it changes and improves everyday) Here are my thoughts on it:
http://yardcrap.typepad.com/yardcrap/2010/08/computer-audio-for-everyone.htmlMore each day sound is not stereo, and computer audio is the only way to keep up.
Personally, stereo has entertained me for years, and I see no reason to change, but I do use a computer as my transport.
