This is a vintage Nad 3020. Every audiophile needs to have owned one or better yet own one now. It has that beautiful warm tone. Its friendly with many speakers and it's been acknowledged as one of the best Amps since the beginning of time. This is the desirable one with the flat RCA plate. It's a bit more expensive than the average 3020 because it the desirable one and because I don't really want to sell it. If you going to wrangle and be difficult then move along. It's worth the money and more. I'll just listen to it a bit more.
