In Reply to: RE: SE 2A3 biasing : non-linear vs. linear biasing ...graphs posted by dave slagle on March 30, 2014 at 13:35:10:
within a defined subsection of circuits, in this case, direct coupled 2 stage SE amp with a 2A3, seeking results that "measure better" by changing a few basic variables (admittedly amidst many more) is still useful stuff IHMO.
The small parts count in an amp like this (except for those that prefer multiple bypassing) puts more percentage per part as being responsible for the final sound/performance. So, if by tuning the operating variables for measure best, the remaining parts are then the only areas where something "might" be able to be improved, example cap quality, or wire or other things not likely to make a "big" change.
The only other thing is that maybe loading higher to lower distortion
at a point starts to sound "less good", even though it measures better.
I've not heard too many complaints from others about this, again, specifically regarding this type of circuit.
