What might help is if you make the x and y axes the same on the before and after versions of the graphs? Initially, I thought the "fixed" performance was worse.
OK, I guess as long we are all OK with calling input attenuators gain controls, and *definitely* not volume knobs.
"Exact same outcome" is another one of those things that you might want to mean one thing, but then someone else doesn't see it the same way. For example, a Class D amp vs a Class...
I keep seeing that amplifier knobs control gain. I would like to see one such knob that actually does that, rather than the usual voltage divider that attenuates input signal
Interestingly, the A70 has better higher-frequency sweeps than the PA7 Plus, although the latter has slightly better multi-tone IMD performance. I strongly doubt you would be able to hear any difference between the A70 and the PA5, and possibly even the A300 when thrown into the mix. Except for...
