To Bi-wire or not?

I was using Tara Labs shot-gun cable to connect my Usher speakers, leaving the jumpers in. When I switched to Blue Jeans cable and true bi-wire and removed the jumpers. I hear no improvement, in fact i lost some bass. I contacted Blue Jeans to see about cable burn-in but they said burn-in is a myth. I have heard that bi-wiring a speaker with low end cable is better than using higher quality cable in non bi-wire application. Any thoughts?

welcome to a feature that (on many speakers)should have been done way with a decade ago.

when i bi wired my infinity renaissance 90's i ran into the same problem that Tbromgard had, bass loss, i thought that my speakers also sounded better with a single wire too.

You've changed two things at once (cable type, and bi-wiring instead of single-wiring), which makes it hard to provide a meaningful response. I suggest that you try the Blue Jeans cables single-ended, with the jumpers in place, preferably with the high and low frequency wires in parallel, or if that is not feasible then using the low frequency wires and leaving the high frequency wires unconnected.

Bass performance can be compromised by some combination of high cable resistance per unit length (i.e., too small a gauge, meaning an AWG number that is too high), long cable length, low speaker impedance, and/or high amplifier output impedance. Let us know as many of these parameters as you can, and we'll be in a better position to help.
