Amazing amplifier for the money. I had it driving all sort of speakers, and it seem to handle all of them well, including the notorious ATC speakers. Its a warm sounding amplifier, so it mates well with everything, it is the QUIETEST amplifier I have ever owned, and i have owned many along with bryston, classe, vincent, parasoud, and more. Which was why this was the last piece of equipment I kept I bought it new 2 years ago in best buy, and do not regret the purchase. However, I am selling my remaining audio equipment. I just do not have time to listen anymore. And besides, the amplifier warrants a much better speaker then my NHT SuperOnes. My lost is your gain. I can ship at buyer's expense since I do have the original box. Pick up prefer in Arundel Mills, MD 21076.
