I am in the tube world for past year and i am hooked. I bought couple of cheap tube amps off the internet and fell in love with tube sound. Recently i came across this little chinese made tube amplifier called sherwood DT-555. Don't bother searching for it, i tried everything and i couldn't find anything. So that's not the story
my question is "Does all tubes produce some kind of very low level noise hum / buzz which can be picked up in zero silence of headphones like HD650?"
I can hear it on my amplifier when it is in zero silence, no songs playing, everything zero. I can only hear this on HD650. All my other headphones doesn't work with this amplifier because they become noisy ( low impedance headphones have a problem with this amp)
I tried rolling the tubes from "Tungsol 2c51", Russian 6n3-p, 6n3-EV, GE 5670, Chinese stock tube 6N3. They all have the noise, and it is least at Tungsol 2C51.
I just want to know if this is normal on tubes....! it is no there when i plug the headphones directly to the notebook.
PS : this hum is very very very low.... nothing that could even barely disturb the music.
