Bel Canto Design Ref600M

Pair of Bel Canto REF600M Mono Blocks, in very good condition.
No blemishes that I can see.
Two pair of these are available. Price is per one pair (two mono amps).
Color is all black, black face, all black aluminum chassis.
I'm not the original owner.
One pair, 294 and 336 have no service history that I am aware of, and they all work perfectly.
Serial Numbers 164 and 1654 have the newer upgraded power supplies performed by Bel Canto.
No smoking and no pet, no kids environment
Selling items as I’m downsizing, dozens of amplifiers here.
All original packaging.
