I've got a chance to pick up a used RX-V2095 for a pretty good price. But price not being EVERYTHING, I'm wondering how much has changed in this last few years with Yamaha amps? How does this old amp compare with say the RX-V2300 or RX-V1400? (I'm trying to keep my amp purchase well under $1000.) What will I be missing out on if I get the 2095?
