I was reading about some issues regarding PR amp and different set of phones, some phones are too sensitive with low impedance which creates problem with the smooth volume for them. Larry fixed that issue by adjusting the gain resistor value for the PR.
My PPA will likely to be used with different set of phones, and having to adjust a R4 gain resistor every time seems to me like a workaround rather than a solution. I'll see what happens with a generic 10k value for it, if it doesn't work well, try to create some tweak here. For example, NAD has a built-in circuitry to recognize different speaker impedance.
