I am one of the newbies guess have lots of company. I am in the process of buying a RV-X2500 with 130 watts per channel output. I believe Yamaha is updating this to 180 watts. My question: Do I really need the extra 50 Watts? I am planning to buy the M60 set-up my room size is 16x19x8 which opens to dining and kitchen area. Would appreciate comments on the Yamaha and suggestions. Sincerely, Tuneman
