currently Yamaha RX V850 driving Monitor 70s. Music only / room is not that large, stereo only, not likely to surround sound. No sub now & none wanted. Current receiver is 80 watts per. Any advantage to more power? If so, suggestions? I see a lot of nice HT stuff but thats going to have bells & whistles I don't need to pay for. Don't know if its worth looking into upgrading & if so, some ideas on where to start. I'm not afraid of older equipment if it suits the need. Listen mostly to classical, jazz & voice via LPs, CDs & FM radio (I have the most awesome antenna). TIA.
