Crown is a good choice for the price. I use 2 XLi800 for side and rear SACD channels. Found a great price at 210 each open box. IMO a better and more expensive amp, any DAC Cherry or variant with the 60volt power supply. The bass is just perfect for my taste. They play loud or soft effortlessly. They are totally black until the music erupts out of the speakers. For two channel I use an older DAC4800 and two King Marischinos
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.
