Freaky speaker experience:

If she's game, perhaps your wife could change from single to bi-wire a few times without letting you see. She should also not change them at all, just pretend to, a few times. Then do the same for her.

I'm open to there being a real difference with bi-wiring (that couldn't be achieved with a single run of the equivalent gauge of a single wire), but I've never heard a convincing explanation for why there might be a difference. The explanations always sound very hand-wavy to me. I'd like to seem some actual math.

Even so, I made some "true bi-wire" cables for when my new Vandersteens come. Cost for materials was under $40. By "true" bi-wiring, Vandersteen means keeping the two runs separate by at least an inch instead of having them in the same jacket. But I did this more because I could than because I expect to hear a difference.

I'll third Rleff.

The placebo effect works both ways.

Kal

To hear an effect that is the exact opposite of what is expected is an indicator that the placebo effect is not at work, and the reality is overwhelming the expectations.

If the placebo effect worked both ways, then the placebo control in medical double- and triple-blind studies would be unreliable for setting the statistical baseline.

I am going to have my wife try and trick me by bi-wiring and not bi-wiring; good suggestion. I want to make sure this is real. Plus play more music. But it was such a change that I believe it is real and not what I hope is real. I hated to think that I had to sell those huge heavy things in this market.....

No I tripple checked and the wiring has always been in phase.

Did you go back to bi wire to see if it happens again?
