Thanks Fried : That is indeed a tour-de-force in well thought out explications, one which seems to break everything down about line level inputs and outputs, related questions of input/output impedance, and interconnects. There is a wealth of information in that post about these particular features that far exceeds what one can find in the manuals of the two units mentioned. Thanks, and much obliged! Yet, because of my own lack of technical expertise, I feel there are parts of the post that have gone over my head, and wish there were someone else who could explicate/translate those parts to me in simpler more layman terms. Still, this is me expressing my appreciation, rather than being un ungrateful pain... I truly feel lucky to own a machine like the V281. Thanks again.
