That's the one! The seller was none other than Paul McGowan of PS Audio, and he only bought the unit for evaluation. He didn't volunteer any opinions on it, though.

I've been trying to get a G61 for some time, they seem to be rather sought-after, and worth more than a G68, which might have made a more logical test-bed. It was difficult to value a used C61, as I've never seen one sold before, but I was getting a bit desperate. The C61 is a challenge though, and the combination of power demand and space availability cuts the options down.

I have another big catch coming-in this week, as well. I'm looking forwards to hearing what controller PSU mods can do for DSP speaker systems as well....
