RE: These things are so system dependent...

Increasing the capacitance is a totally reversable mod.

If you're a purist, replacing a selenium rectifier with a silicon one and adding a series resistor to provide the correct voltage technically makes it a modified unit because it no longer matches the schematic. Marantz most likely would have used higher capacitances in the power supply when the 8B was in production except for the high price and large size of higher capacitance cans in the days of yore. What they used nevertheless worked well, and that's what we have.

I think the mods that cause the devaluation are the ones involving significant circuit changes. Even a mediocre technician understands why someone increases the capacitor values in a power supply.
