I don't really want to sell this, but it's time. I've had this for a few years and used it as my main amp and then as my desktop amp after moving up the Mcintosh integrated line. Up until last year it functioned perfectly, and I preferred the sound of the aux in for digital sources over my MA6200, but about 9 months ago it started making intermittent popping sounds through the speakers while playing any input. It's totally unrestored, so I'm guessing it's in need of a recap, or maybe just some solder joints need to be reflowed. There is some corrosion on the chassis, and some minor scratches/discoloration on the wood case. Overall it looks very nice. The glass is in great shape.
I'm only willing to ship if you have an official McIntosh double shipping box sent from audioclassics.com
