RE: Excess Line Voltage vs Amplifier Sound

Posted by xaudiomanx on January 9, 2017 at 13:40:11:
I can't comment on what you are experiencing sonically but I do know using the older transformers designed for 115VAC will give you a higher B+ if the B+ isn't dealt with by lowering it. That does shorten tube life but usually what I've always done with that is lower the negative voltage on the grid. As for sonics I do know if you overdrive a tube(which is what a lot of the so called "modders" do) it can tend to sound thinner with less attention to the bass. I don't think it's the bass that is compromised. I think it is more the upper ranges become more prominent. But I too am a novice with a small opinion but I do know what I hear.

Also, I was told by many in audio whom I respect that any type of device used to either condition the AC or lower it squashes the sound stage. Now! That I did experience. Not to a huge degree but in an A-B comparison I did hear it. I was always told the only units that should go through a line conditioner of any type should either be a CD/transport-Dac or a preamp. Anything needed to draw a lot of current should go directly to the wall outlet.
