Found it better than my Denon AvR 2805 100 channel amp. Put my ear on the speaker and it was clearer on A07 max. I heard distortion using my Denon. Believe it or not Im using that amp full volume on large bi amp speakers that push up to 300w.
Easier teardown ... take the volume knob off, remove the nut underneath, take the two outermost screws out of the back, slide the whole thing out the back. Op-Amp wise ... don't waste money on exotica. Plain old JRC4558s at about 50 cents a piece will give you a noticeable improvement. FWIW the actual improvement is not putting in fancy op-amps, it is in getting the crappy 5532s out of there. For power ... with a 48 volt power supply you will get an honest to goodness 100w/ch with very low distortion on an 8 ohm speaker, up to 200 watts on 4 ohms. Speaker wise... these amplifiers are wasted on desktop speakers. Try letting them loose on something like a pair of LaScalas, Heresys, L-100s or Lintons... now that's a real treat.
