+1 for the Cherry amp. Have one pushing a new pair Spatial M5s through a Mytek Brooklyn Bridge. A relatively new offering of theirs is called a 2 Cherry (King version or regular). Puts out 400 into 4 ohms with 1000 watt peak (200/8 ohm). Very controlled, clean and smooth. Right in your price range should check with Tommie O'Brien the owner for deals. All US made, his proprietary built in-house Class D modules. Been at it for over 25 years.. Liking mine a lot. Cheers
Class-D recommendation
Looking for a class-D recommendation for the base portion of a multi-amp system w/ active xover. The amp will be powering a pair of 15" 4Ohm woofers from 30 - 600Hz. Need at least 400W, very high damping, and clean into the midrange. Everything above 600Hz is taken care of by a class-A amp. I would prefer to spend <$2k used.
