There is a local guy whose selling a Mcintosh ma-6100 and he says it's in very good condition. He wants $400 for it and I have been doing a lot of reading about the 6100 and looks like it is a good amp. Since I don't have any experience in the mac products, can somebody comment on the 6100 and is the price right? Positive and negative comments are most welcome so I can decide whether to get it or not. :yes:
