PM-10 is sounding good on the (very) limited time I get to listen. Believe it or not, I think it will replace the McIntosh MC601/C50 combo, however, as the Marantz will accept another pre-amp on board, I will hook the C50 up to hear the differences. Hell, maybe I will bi-amp the JBL 4365 speakers down the road. Since I have the SA-11S3 sacd player, I am in no particular rush to acquire the SA-10 (although I would love to!).
