Anyway, the point is that with all mods (pads, grill, and felt) the HE-6 comes very very close to the SR-009 in all technical aspects. With a very good amp, HE-6 has presence and dynamics that I don't think the SR-009 can ever have. The lead the SR-009 has isn't as clear as it should. Which reminds me, my close friend owns an 009 that I could probably borrow for an extended period of time. The hard part would be acquiring a Woo Wee.
