When I first found this forum, I went to Portland Oregon & found an MC50 in a really cool junk shop call "Really Good Stuff." Weird place. Lots of old antiques, movie projectors, some audio, & some well used gigging equipment. I passed on that $200 Mc50. Still wish I hadn't.
I did find a 2100 for about $300. Glad I have it. Freeeeeekin' heavy. 65lbs sounds light, but you can barely get your fingers under the thing and it's dead weight. In a rack rig without roadies...Ug. Drives the home stereo perfectly. It's a strange description, but it fills our house with sound without being loud.
My rig has an Mc250 now. It's still too much for 1 guy. Mc250, SMS, GCX, Furman, Pedal drawer. Easier carry with 2 people.
50 McIntosh Watts is loud! I don't play out much, and it's usually small spaces, but I've never really cranked the thing. Like to!
I'll eventually find another Mc50. Watch CL. They're typically cheaper there. Single Mc50's can be reasonable on Ebay as well.
