I'm currently looking at a Yamaha RX-V1 receiver on Craigslist. It was Yamaha's flagship receiver about 12 years ago. I believe it's something like 100 watts per channel. All of the reviews I've read have said it can handle 4 ohm speakers with no problems. But can it handle five 4 ohm speakers, RTA12C, Monitor 7C and Monitor 5B's or would that prove too much?
