I have a pair of RTi-12's that I purchased over a year ago. I am driving them with a Yamaha RX-V 765 (100W per channel), running 2 outputs to each speaker in bi-amped mode. I am not satisfied with the sound quality and am looking to purchase a Rotel amp to drive them. My local Modia store has the RB 1572 (class-D) and the RB 1582 (class-A&B) amp.
Looking for advice as to which amp is better for the RTi-12's. Suggestions?
