Synergistic Research Tesla x4 speaker cable

Guidocorona has it correctly in his explanation above.

It's an issue of improper installation rather than the cable itself.

Just be sure you have plus-to-plus and minus-to-minus (or red-to-red and black-to-black).

I will give it a try. I have red to red and black to black on both the amp end and the speaker end. If I understand yall correctly, i would swap at the speaker end and got red to black and black to red.
Can I damage anything doing this?

I did try playing with the phase button on my jrdg pre but it didnt fix the problem.

Jimmy, no damage possible. . . but you must change only on one wire, and only at speaker end. Phase switch on preamp or on source is an 'absolute' phase. . . it generally makes little or no difference. G.

That's correct. I wouldn't change it unless your preamp inverts phase, but I'm
sure you know that already.

You could always swap the connections (red-to-black, and black to red) at
either the speaker end or the amp end (not both) and listen for a difference. If
you did hear an improvement, it'd be good to have SR look at the cables. It's
possible they put the wrong color coded connectors on one end, which would
result in an out-of-phase installation.

You could use an ohmmeter to check the cables. Disconnect the cables from the amp and speakers and connect the ohmmeter between the red amp end and the red speaker end.You should get a reading on the ohmmeter. If not the cable is mismarked.
