Does the"quality" of jumpers affect the sound?

Clio09, that's exactly how I do it. I honestly can't tell if there is a difference or not.

Make sure you speakers are capable of this first. FWIW, my speakers (Verity Audio Parsifal Encore's) have jumpers, but are not bi-wireable or bi-ampable. They have one crossover, and it is in the bass module. My speakers were designed for the speaker cables to be attached to the woofer module. Otherwise the mid/tweeter would be run full range, which could damage the drivers.

So know your speakers design before trying some of these suggestions.

Anyone ever try wiring the positive to the tweeter and negative to the bass while using jumpers?

Yes, that is the best way to single-wire if you have to. Otherwise, whichever part of the speaker you connect directly to will sound noticeably better than the part that gets its sound via the jumpers. The + hi/- one low method results in the most balanced sound across the entire speaker.

Jumper quality matters, but it doesn't take much to have very good quality for such short pieces.

Has anyone here tried the Cardas jumpers? I bought two sets of the Rhodium plated coppers and like them quite a bit but wish I would have just gotten the pure coppers to be honest.

Notwithstanding the statements about jumpers making a difference and connecting at either the high or low side, cross wiring + to hi and - to low, cannot make any difference since the current is AC and effectively the + & - change continuously according to the frequency.
