IMO, $1200 "is" less due to age. conrad johnson still offers full support for this amp, including full refurbishing back to original spec and/or upgrades. It's a well made amplifier and a good tech will be able to keep it going indefinitely. I'm not trying to influence you, just offer you my perspective. Of course, the condition of the amp should have a bearing on its price. If it were me, I would want to know its maintenance history.
