Speltz Anti Cable Speaker Cable

I tried it and could not get a good tight fit with the double spades on the amp end. The stiffness of the wire didn't help either -- one side would pop out while I was trying to tighten down the other side. Very frustrating. The sound from my Tylers was worse with the bi-wire, perhaps because the spades on the amp end weren't laying flat on top of each other. I went back to a single run with jumpers and the sound was more focused and dynamic.

All this proves that every system is different. A recent article, I think it was in Stereophile, examined amplifiers and their changes under different loads at different frequencies. Each amplifier has varying characteristics at different outputs and at different frequencies. This means that different cables and speakers will present different loads to the amplifier. There are simply too many variables to make any meaningful conclusions. Part of the fun is trying out different parts to hear how they fit. The Speltz worked fine for me. Since I changed the acoustics in my room I found that untwisting the wires sounded better-more natural highs, better spatiality and no edge at all. I have given up recommending components or tweaks or wires. You'll just have to find out what works for you. And, remember to have fun. Buy used and sell what doesn't work for you- it will for someone else.

Can you bend the end of the wire in a loop to fit around the binding post, and then lightly hammer the wire to flatten it out a bit in order to increase contact area?

It is almost the same as working with coat hanger wire so bending and flattening shouldn't be an issue.
