Yes- higher orders at only 80dB down will be audible as brightness and harshness.

You need to get them a good 20dB less and then they start to be 'nearly' inaudible. That's why its almost impossible to put enough feedback on a tube amplifier- usually the phase margin is exceeded. We make tube amps with arguably the best phase margin out there and its hard with our stuff too.
