Emotiva XPA-1L monoblocks, about $850 for the pair. The first 35 watts are pure Class A. Every tweak I throw at the system, and I seem to find one every week, yields better sq. So, I have not yet found the limits of the system. The blocks drive a pair of KEF LS/50s and the sound is so clean, with gobs of detail, bloom, and punchy bass.
I will add that I've been working hard on the system for over a year and have learned that taming room acoustics also yields a lot of bang-for-the-buck. Buy ASC tube traps if you can find them.
