After installing Fideliums in my system, my thoughts were that there would be a flood of high priced speaker cables on the used market.
I was using very highly thought of $6K cables that are now relatively junk in comparison.
A main feature of Fideliums is that they use no terminations. However high end the terminations, they greatly degrade the sound.
Another very innovative and smart feature is that the $125 biwire adapter is a loop of ribbon with a screw connector in the middle which allows the signal to go into both pairs of binding posts at the same time equally.
And even though they look problematic to attach, I had no problem.
$1200 for an 8’ pair is a steal.
