Scored this on ebay. Listed as untested. They accepted my offer of $80+shipping. It powers on and is aesthetically unbelievable. Seller primarily sells random car parts, so I'm confident it actually is untested. So far i have powered it up no problem but i haven't tried to get sound out of it...

Hey guys, looking for Yamaha YPA Amplifiers. If you have any you're looking to get rid of let me know. Thank you,

So I'm trying to figure out if my YPA-700 would be enough to make 2 Infinity 609CS 270W component sets sound good. Or do I need to install 2 of them? Run each at 2 channels. Or run one YPA-700 and a YPA-1000. The 1000 for the fronts and 700 for the rears? I'm trying to get the best sound I can...
