I acquired a Carver m500t a while back, and used it with an NAD 1600 pre. I was immediately satisfied with the sound when used with my HK tt and KEF 103/4 Reference. Despite this satisfaction, I dug out my Yamaha cr820 and substituted it for the Carver/NAD combo, just to see how it compared. I don't know if I will go back! This Yamaha is awesome, not to mention it looks really good. Dave Brubeck is clicking and clacking to "Unsquare Dance" as I type, and it never sounded better. I realize that some folks just hate old Bob Carver, but I will never give up my m500t, (unless maybe I were to use the money to rebuild my Dyna Stereo 70). Anyway, anyone else running the 820 out there?
