I'm using some old school Arc Audio amps that spec input voltage at 2.5Vrms. My DSP spec's 6.5V output... I have no issues even on the loudest transients.
That's great info! Stands to reason there would be some variance. I'll probably just set my gains using the standard method and move on. Would be nice to have an o-scope to do it scientifically but, such is life.

Any additional real world input appreciated though.
