As mentioned above, I'd suggest a McCormack DNA .05 or 1.0 amp. I have the former and it is the most musical amp I have had in my system in 45 years. It is very powerful and musical. A few DNA .05's are available currently on the aftermarket and they can be upgraded by SMc Audio if you are inclined. Odessey makes fine amps, but the McCormack amps are a glimpse of nirvana. Sunfire, in my experience, while well-made, are decidedly mid-fi to my ears. The Plinius 8200 MKII integrated amp, running as power amp, is very powerful and, to my ears, warm and engaging. I wish I had never sold mine.
