I have a PS Audio power regenerator in my system currently set to 120V.  I originally added this to help address significant low voltage (109V) to my listening room that caused the 300B to start making noise.

Since I can adjust the output voltage to whatever I want, what is the ideal voltage for the 300B from perspective of noise, heat, and longevity in that priority order?

Everything in the BeePre with regards to the 300B is regulated, so the 300B won't notice line voltage differences.  The filament regulator would appreciate having 120V coming into the power transformer though.
