Your welcome. In the dawn of the PC age with the old school ISA Soundblasters and so on, they had "speaker/headphone outputs" and "line outputs" then later the makers combined them into one output. I have no idea if they have circuitry to detect what is being driven and match impedance but I have had the experience many times of a set of powered speakers sounding like crap on one card while sounding quite good on a different one, so I know there must be impedance mismatches with certain speakers and card combos.

Ted, That's what I decided, too. I just ordered a dual-direction mini-phono switch box with volume control; I'll use it as 1-in, 3-out. That way only one output at a time will be active and powered. Thanks very much, Rich
