Call Glen at 'Audio Two', in Windsor, (519)-979-7101. He sells lots of used gear and knows a great audio technician or two. I'd look at it myself, just to get a look at the innards of those particular models (I'm always curious), but I'm 600 miles away.

Try Glen, he likely knows someone who is closer to you-on the US side of the border, if you are too far away to zip down to Windsor with them.
