I've had this amp for a couple of years. I decided to swap it for a 100W/ch Benchmark AHB2 because my new GoldenEar T-Refs don't need that much power as they have built in woofer amps. Class D operation, excellent sound, Steeeophile Recommended component. Excellent condition, comes with original box, manual, and power cord. Wll shp. I have an extensive collection of vinyl and a decent collection of SACD's to audition with, if you want to bring CD's or a streamer and output cable that will work too.
