That seems backwards to me. Normally the higher the idle current is in the output devices the more linear they are. (up to the mid-point between cutoff and saturation)

The only thing I can think of is that either the engineers screwed up or a wrong valued component was accidentally put in both boards. But NO amp should sound like this thing did at correct bias.

I did try turning up the bias from 6.6 (+/-1mv) to 8.5mv. The darn thing ran hot as heck with no improvement. It still sounds MUCH better with the bias at 4-4.5mv.

Initially this amp ran as hot as a Class A or tube amp. I'm thinking the bias was set at saturation.
