Hi, I'm new on this site. Seems like a really good source of info. I have a nad 524 cd player and rotel amp. The cd player doesnt play cdr's etc, this is very annoying now but the player sounds great. I bought it ex-demo and thinking about getting something newer which plays all types of cd and must be as good or better. Is the c521 bee as good, as it seems a little cheaper, or should I try the more expensive 542? Or is there perhaps something else that would sound great for 180-260 ex dem or new.
