Traditionally we've always used Exeltech, as they've had the cleanest output, with background buzz on tube amps being lower than grid power.  Modsine were horrible, Old Trace SWs were pretty intolerable, Magnum's were usable, but still noticeably more buzz than grid.  I think THD is roughly associated with the background buzz, but there might be certain harmonics that are particularly problematic.  I haven't gotten into looking at the separate harmonics relative to what induces the most noise in these old vacuum tube circuits.
