I just bought Confidence 5's and am driving them with a Krell FPB 200....rest of system is Levinson....the amp works well, drives them withough difficulty and sounds very good....I also, however, am looking for a different amp, possibly Levinson to connect to rest of system, or another I can leave on permanently...I am wondering about the new Bel Canto EVO 200.2 bridged as mono or the new Bryston 14Bst...both would provide more current for the speakers and they are somewhat inefficent...let me know what you discover..
