yesterday i browsed this forum way too much and finally decided to get a dedicated CD carousel, the Sony CA70ES. The most important reasons to upgrade were better oversampling for CDs with scratches and carousel capability. I did not expect a difference in sound quality between the CA70ES and the panny RP56 because of my Infinity RS2002 bookshelf mains (old and cheap), but there it was! The CA70ES sounds more "consistent", warm and focused (using analog outputs; haven't used optical). the difference is, of course, small overall, but with concentration is always apparent. anybody thinking about a dedicated CD player, do it NOW! the difference will probably be more apparent to most people here.
