Your case is quite similar to mine in some ways: 1950's home, no grounding, moderately sized listening room. I added an Outlaw Model 750 in the summer of 2001 (a little less total power than the 755, but still pretty stout), driving Paradigm Reference speakers (Studio/60's, Studio/CC, and three Studio/ADP's). Initially I used my old Model 1050 to drive the third surround, but late in 2001 I added an old Parasound amp. The listening room is 11'x19'x8'. The circuit it was all connected to was ungrounded and shared by the microwave and refrigerator. I had a little bit of buzz from the fridge, but never had any other problems. I added a dedicated grounded outlet in the spring of 2002, which took care of the buzz. For what it's worth, I would recommend the addition of a grounded outlet at some point for a little extra security and better sound, but you could probably delay the electrical upgrade until finances permit it.
