Reissue McIntosh MC275's..what are differences?

And which is the best do you think?
Any comparison to an original that is moderately restored?
Theres a lot of them about in the $3-4k range..sure would
like to get a near mint one for an exceptional price.
I'm pretty sure its the same amp with some modern upgrades like better binding posts and connectors. If you call McIntosh, they can list all the differences. I spoke to them with other questions, and they were pretty knowledgeable.
