I expect it means either: 1) the power supply is non-switching; or 2) the amp itself is biased heavily into the class A-B region or is fully class A. In case 1, the output of the power supply is not controlled by the audio signal (such as in Carver's "magnetic field" amps), nor does it use a "switching" regulator. It's just a standard old analog or unregulated supply. In case 2, the larger bias on the output transistors means that they stay in a more linear region of operation. I doubt that the amp is class A or they would have said so. Without more facts..... Perry Emrath, UofIL ...{decvax|inuxc}!pur-ee!uiucdcs!emrath
