AF,reading between the lines a bit, it appears that you're unnecessary concerned because of some inaccurate and misleading info you've read somewhere about your 3805. First, the FTC regulation on amplifiers(16 CFR Part 432) requires that they produce the rated power for at least five minutes continuously with "all associated channels" driven simultaneously. When the reg was being formulated in the early 1970s nearly all amps had one or two channels, so "all associated channels" could only mean two. Although multi-channel amps are now common the reg language and interpretation hasn't been changed(it's been under study for about four years)and most makers(HK and NAD are two exceptions)continue to use the two channel simultaneously spec.
The point therefore is that your 3805 exceeds its power rating of 120 watts with two channels driven, as the test John(NeverHappy)reports shows. Actually those numbers are conservative, since S&V uses 0.3% distortion as "clipping", and that's far below actual clipping or audibility on music.
"All channels driven" continuously can be tested under lab conditions, but rarely if ever occurs in the home and far too much attention is given to it in some audio circles. Incidentally, even if the 3805(or some other amp)could do 120 watts into seven channels continuously(rather than the tested 93 watts)it would represent only about 1.2dB more in peak loudness(say 111.2dB instead of 110dB). The bottom line is that your 3805 is a very powerful receiver and it's unlikely that you have any good reason to be thinking of a change.
