what to try?

I've used bi-amping successfully for several years with a pair of Quad 303s so upgraded they give 'Trigger's Broom’ Paradox' a run for its money. The difference between one amp and two is, in my case at least, very marked with SQ distinctly improved.

I use one amp per channel (not one for HF and the other for LF as you do) so the only link between the two is a common power connection. It's not, for obvious reasons, a permanent solution but the first thing I'd try is the one-amp-per-channel scenario. At least you might discover (or perhaps already have discovered) something.

I also ensured that the crossover circuits in each speaker (LF and HF) were electrically separate as it seemed a sensible precaution and was easy to do.

Could your DC-at-the-pre-amp hypothesis not at least be tested by putting a suitable capacitor between the pre-amp OP and the tube amp IP (correcting for phase reversal by swapping one pair of speaker leads)?

BTW, are you still using a Lampizator pre-amp?

Yep, the pre is still Lampizator. - carcass93 09:04:39 01/15/15 (0)

What part of "shift focus from "viability" of the idea of passive biamping" did you not understand? - carcass93 20:07:58 01/14/15 (2)
