Finally got mine up and running.
Feeding directly via Synology Nas to PWD MkII to BHSE and out of SR-007.
Are BHSE supposed to run noise free?
The reason that I am asking this as there is a noise like something is vibrating from the main unit with the tubes. Kind of like you hear when a light bulb is going bad.
Otherwise, liking it so far and the shipping box minor damage hasn't done anything visible to my unit.
Yes, my BHSE is noise free. It's actually the most noise free amp I've ever owned.
I can turn the volume to the max and hear the faintest noise above 3 o'clock.
Perhpas you have one or more bad tubes?
