what kind of input tubes did you try ?Yea.. I’ve even tried it with nothing plugged into the input and noise is still there. This seem to only happen with my dynamic driver headphones strangely. I previously had a Diana v2 and there wasn’t any static noises using that.
Sounds like you're having bad luck with noisy tubes...
also try to go single ended out instead of balanced, and low or medium impedance setting.
this will reduce the noise greatly;
balanced will be perfect with no noise with low sensitivity headphones ( like your dianav2) (91db sensitivity )
for example with focals (104db sensitivity ) it is better to use single ended
for the verite at 99db, I would stick to single ended, high or medium impedance, don't worry too much about the setting, juste use the one that does not bother you, there is plenty power on tap, even with the lowest setting....
if there is is still noise, maybe swap the input tube for nos sylvania 6189 or 5814
New production JJ or eh gold are not bad for noise.
I would avoid shuguang or psvane 12au7, I had bad luck with those...
your bifrost 2 shouldn't be a problem, I have it as well, and the usb connection is galvanicly isolated, so it cannot induce ground loop.
