“… effortless top end… such clarity that it set a new benchmark for me for high-frequency reproduction and detail… it reproduced kick drums with power, heft, and control usually heard only from amps with twice the power output… despite its modest output spec into 8 ohms, the M-900u is actually a powerhouse.”
“… the best-sounding power amp I’ve ever heard… The M-900u is one of the best values in high-end amplifiers.”
