PS Audio GainCell:
The gain of the preaamp stage itself is electronically controlled as needed to adjust volume level. This is different than most preamps where the gain is fixed and the signal feeding it is attenuated. The traditional volume control (attenuator) does not exist in the GainCell and is not in the audio signal path.
Paul claims to have invented the GainCell. He may have invented the name but the technology has been used by others. I don't recall the details but the concept has been around before Paul's "GainCell".
He uses the little GainCell module in various PS Audio products.
