I have tried bi-wire several times over the years on several different speakers and sometimes there was a difference and sometimes there wasn’t. I have always wondered about that cheap piece of steel most speaker companies seem to use. So a couple of months ago, I bought a pair of good quality jumpers and the difference on my KEF’s was immediate. Could this be the difference I heard when I tried bi-wire, the bypassing of that cheap piece of steal?
live and learn!
