So, I bought both Denon PMA 770 and Canton Karat 300 (100W per channel, let's see how that goes). I still haven't had much time to listen to the system, but I hope to do some A/B testing (Karat 200 vs Karat 300 on PMA 770) in the upcoming weeks.
I'll be waiting to read your thoughts. Have fun with them.
Cheers,
James
