All I can help with is CD vs. SACD I compared the CD end of a Sony 777 with a Meridian 508-24 and for laughs a Rotel RCD 7??. The Meridian was just slightly better than the Rotel ($3500 vs. $350). I then compared the Meridian and the Sony. The Sony was very annoying to listen to even after messing around with the filters. The Sony was impressive with SACD. I personally would not sacrifice my 3500+ CD collection just to listen to a few SACD's that are currently on the market. Maybe in a few years. I say save your money and buy a Rotel or a Rega until all of these format choices are clear. BTW - I still love vinyl.
