Some of the Class A amps mentioned are very good I had the ATC SIA2 for a while and it is a very good amp. Depending on the amount of inputs you need look into the Digital Amplifier Companies (DAC) offerings. I'm currently using the 2 Cherry with their DAC DAC2 HSV (the combo fits in your budget) on my Charney Audio horns with superb results. Very smooth non-fatiguing detail in the highs, engaging mids, and deep controlled bass. A very well balanced presentation. DAC offers a 30 day return policy, so you can do an in home demo and only be out the shipping both ways.
Hope you find what your searching for.
