Hiwatt bias really too hot : best or worth amp ?

Hello & Happy New Year 2013 full of Hiwatt Stacks to Everyone
I checked the bias on my DR504 '72 with Svetlana Wing =C= and I got 70mA & 80mA @ 414Vdc !!!
I read that an amp too hot is sounding like hell but of course won't last long. Like this, the amp is crunching when dimed but that's not incredible crunch...
My question is : the amp will become a lot less crunchy with proper bias ? I don't have the sag I got with my old '71 DR103 (that I sold) when master pushed in this DR504...
In fact, I found it a bit cold sounding...
I guess I will need Mark Huss voltage doubler circuit to get the proper bias.
