Manual vs. Auto Bias


In considering new directions in which to take the evolution of my system, I have run into conflicting claims as to which results in less distortion...auto or manual biasing, according to what product(s) the so called expert manufactures and/or represents...(Surprise!) How about some input from average consumers like myself who have had more experience with one or both?

I have had a cj tube amp required biasing using the lights mounted on the amp and now cary using a meter, both are easy. Although I guess I prefer to use a meter so I know exactly where the bias is set. Both amps required biasing and were not automatic but not a big deal to adjust it infrequently.

I like a manual bias as it allows for fine adjustments to squeeze the last drop of performance from the tube and circuit.
I have auto bias. It sounds good and I barely know what bias is. I pay to hear the band, not to make the music.
