A fellow audiophile and friend has a set of Harbeth 40.1s and now uses an Emotive XPA-2 stereo amp; definitely meets your price criteria. It has pits of hell bass, great high frequency and midrange response and drove the Harbeths without breaking a sweat. I was shocked at what Emotiva had packed into this fine amp. Another friend of ours swore by the monoblock versions of the same amp.....
