I'am ready to buy a new av receiver (yamaha rx-v995 i own is ready for retirement).I really like everything about the nr-905( toroidal power supply,video processing chip,thx ultra 2,build quality,network capable,etc...), but i hesitate because of what i've been reading about how hot the nr-905 gets and the report of a "popping sound" at certain times heard in your speakers.Heat and electronics don't go together, for i am concerned about the 905's longevity, but is it really as bad as everyone is making it out to be? I have the yam 995 for ten yrs. and a yam 495 for 8 yrs. and have never had a problem with either(and they never get worse than warm), but besides that i am willing to try an Onkyo.I like the 3800 but feel the 905 outshines it in many areas. Am i worrying for nothing? What should i do? Any help would be greatly appreciated!!!
