Vintage McIntosh gears have been growing in collectibility over the years and for many good reasons. They are built like tanks where they can probably last for generations of ownership (with proper maintenance). The MC2100 is one such amp. Weighing close to 60 lbs, this is one hefty amp. Its physical dimensions of 11″ wide, 7″ tall and 17″ deep will fool you into thinking otherwise. While the massive transformers make up the bulk of the weight, it is also responsible for pumping out 105W per channel. If you find another one and run them as monos, they will give you 210W per channel. That was a lot of power back then when it first appeared in the market (it is still a lot of power now). The biggest difference you can take away on the quality of their power output is the remarkable authoritative sound it produces. The sound it produces is powerful, firm and precise. Even the mid-range that has the signature warm McIntosh sound is well defined with a linear smoothness that spans out across the frequency range. If you pair this with their C series of preamps from that era, you will get a richly textured, non fatiguing sound that you can enjoy for hours without any ear bleed.
Cosmetically, the amp is in good shape for its vintage. There are some scuff marks/scratches here and there and some wearing out of the silk screen wordings on the back panel but nothing major. We don’t have the original packaging but will securely pack it for safe shipping. The amp does not have a on/off switch because it was designed to be plugged into the auxiliary AC outlet of a McIntosh preamp (or any other preamp that has the same auxiliary AC outlet). If you choose to go with a different preamp that doesn’t have the auxiliary AC outlet, you can plug the MC2100 into a power strip that has an on/off switch. Amp will be securely packed for safe shipping.
