Crown XLS1502. 300wpc/8ohms, 600wpc/4ohms. $439 from Crutchfield, American Musical Supply and other online retailers. Free shipping! That's my hands-down choice for a high-power Class D amp! No need to spend money on a boutique amp!
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.
