I think the match up should be fine. You can keep the Rega RS1's and then buy the Brio-R sometime if you ever want to upgrade. I wouldn't worry about a power conditioner right now. Save your money for the Brio-R. The power conditioner filters out unwanted RMF radio frequency's from the power. Some say it might give you a quieter and smoother sound. But I wouldn't invest the money in it until you upgrade the rest of your system first. Even then some like them and some don't. Me personally I tried one before and I find that it sucks the life out of the sound. Others may disagree. Good luck!
Rega RS1 speakers compatible with Yamaha receiver?
I'm still quite new to the audio world. That said, I own a recently bought Yamaha RS 500 stereo receiver, rated at 75wpc, 0.08 thd. Am now considering purchase of Rega RS 1 speakers but wonder if they might be a poor match with my receiver, which I realize is not considered "serious" audio equipment. Nonetheless, I would very much appreciate your input - please be kind.
