Summary: I purchased these to go in the workout room so that I could hear the tv over the sound of the treadmill and step machine. Turning up the tv loud enough lead to ringing headaches after workouts. So, I bought these and they are hooked up to an onkyo m-282 dedicated amplifier. They certainly outperform the tv speakers... But, I compared them with a pair of Phase Technology Teatro 4.5 on a yamaha rx-797 (A/B speaker buttons let you switch speakers instantaneously!
Summary: I recently had these RB-61's in the cherry color. They were beautiful to look at and were built solid as a rock. I could not locate a dealer within driving distance and so I bought them site un-seen (Yes, I know. 'Not a smart thing to do). I had them hooked up to a Yamaha RX-797 stereo receiver which has very good specs and is advertised as being made with high-end components. You've probably noticed that I have been speaking in "past tense".
