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.
