Heres what I have so far.
DC Voltage Feed; worst sound.
AC voltage best sound.
DC Current not so bad.

Huh, MB... as always, there`re so many possible exceptions to those generalizations...
If you don`t need experimentations (time & money), then in your case just use AC, this is the simplest method. Only if you are not satisfied with hum and IMD level in your amp, try some DC solutions (DIY or commercial).
IMO/IME and YMMV - of course...

Yep; thats the problem; there are no easy solutions. And even if you do experiment it don't mean you will get the same results on every system.
So now that you have had time to relax with your 300B whats the word?

Sorry, nothing new to add - haven`t got too much time to listen, and didn`t try any new "tricks" , + 35°C ...
