The 500MB is the only amp I bought twice. It has gobs of power (I have had great success driving Audiostatic speakers, that are 72dB efficient), great dynamics and bass slam, exceptional soundstage depth and above avg mirodynamics. The only thing it lacks compared to the very best solid state offerings - like DartZeel for example, is the lack of the last bit of fluidity and HF clarity, and a bit of ss glare.
This is an exceptional amp for the price.
