Hello AV Experts, Currently I have Yamaha RXV665 pumping power to Polk Monitor 70 (fronts), Polk CS1 Series II (Centre) and Definitive Tech Satellites (Rears) and Def-Tech Sub in a 5.1 set-up. I am thinking of buying Onkyo TXNR808, do you think I'd see the difference in extra 35 Watts (Yamaha 90W/Channel compared to Onkyo 135W/C) Please suggest.
