For financial reasons, I am selling my pair of Mark Levinson No 531h mono amplifiers. I don’t see any scratches, dents, or marks on them. Both amps sound amazing. 531h is ML’s current model and sounds better than any previous models. Home Theater’s “Best Product Awards for 2011” - Best High End Power Amp. Stereophile’s 2011 Class A amp (532h). Shipping fee to lower 48 states: $155 for both with full insurance. International buyers please contact me. They come with the original double box, user’s manual, power cord and ML glove. PayPal add 3.5%.
