I've noticed that my S.E.X. sounds better---more ... "delicious"---if I have the volume control open all the way and modulate the volume from the source.
Is this because, as I increase the volume I increase some of the euphonic distortion? E.g., the 2nd order harmonics.
How do you play your S.E.X.? Wide-open and control from the source or the other way around.
Thanks,
Alberto
