Bias on solid state?

My amp has just been serviced - an MF NuVista M3 integrated - and among other things the tech said that he biased the amp. I've heard of biasing tube amps, but this is a solid state amp section with tubes only in the pre. I have heard references to bias on SS A/AB amps, of which this is one.

Can anyone explain what all this means? I'm clueless on it.

Right, but to the best of my knowledge, the Nevistors are only in the pre section of the integrated, not the output power amp section.

Should the adjustment have any practical effect on sound?

Well, I not sure what helped what BUT the pots were cleaned out, the power caps were replaced, and the amp was biased and the results are not subtle. The amp is MUCH quieter and the highs are noticibly smother and more detailed. I have not idea how much of this has to do with the bias, but it sounds terrific. In the end, I guess thats all that matters.
