I have a BHSE and a SR-009. I have changed the original Mullard EL34 tubes to another brand. But the sound of my left side became a bit, how should I say, veiled. The higher the volume and the higher the pitch, the more obvious, like playing songs by soprano.
This still happens after I have changed back to the original Mullard tubes. Has anyone experienced this before or know the reason?
I have no another set of headphone or amplifier to test out the problem.
Thanks a lot.
