There's a set of Nord N1200 monoblocks on audiogon for sale if you're interested:

If you're interested, you will want to ask him what input buffer board this comes with. If it comes with a "Rev A" input board, then you're golden because these can use any of the op amps available. If it has the "Onboard NC1200 Module", I would advise you to avoid this because there is no option to swap out op amps.
Also, the guy is asking pretty much retail price, so I would make an offer at least 25% less.
