Simaudio Moon 400MPrice: $6500 per pair

Doug said: $6500 isn’t cheap, and the 400M’s looks aren’t exceptional -- but lurking beneath their plain surfaces is an outstanding-sounding, high-powered amplifier whose performance is something special. If you dream of owning Simaudio Moon Evolution components but, like most of us, can’t afford them, look to the Moon 400M -- it delivers Evolution-like sound at a reasonable price.
