I don't think one must die.
With MP3 and Windows Media, must one die?
With DD and DTS, must one die?
With CD and vinyl, must one die?
With CD and SACD or DVD-A, must one die?
Why must one die???
Sony just announced 11 new SACD players. Three are DVD/SACD players (one listing for $300 and another for $400). All are multichannel.
SACD is clearly on the rise. Read the www.enjoythemusic.com review of the NYC Electronics Show and their take on SACD.
