Many tube freaks , well me anyway, bias their tube amps on a weekly basis.

Is it real or just my imagination?
I recently checked and re-biased my ARC VT100 Mk II power amp. Tubes had not been re-biased since new, and the hours had reached around 500, so I felt it was time to check and adjust if necessary. Spec is 130. One channel measured 128, and the other 125. I set them both to spec, closed the amped, and took a listen. I was surprised to find that the amp sounded more dynamic, more "alive". I was surprised that this small a change in bias would make a clearly audible difference. Any body else have a similar experience ?
