Chane A5.5 seems a good selection for you. Wharfedate EVO, Emotiva Airmotive T1. You have been listening to a pretty restrained set-up, so I suspect you would not enjoy the more treble-forward speakers that are so common today (Klipsch, Polk, etc., etc.).
Do you have a room that is large enough to place speakers away from walls? If so, then consider the Magnepan LRS (could be a long wait) or a used Vandersteen Model 1 or 2.
I just read that some folks are replacing the caps on this receiver. You might have the engineer test yours for spec while he has the case open.
It's a VIRTUAL channel unless stated otherwise.
