I tried both neotech solid and stranded 12 gauge.I wanted to like the solid but stranded just was smoother...in my system.Mundorf was recommended to me and was nice sounding...but ultimately went with copper.Ultimately zavfinos were the winners over my efforts.
Sound color with different jumper materials,
Change the sound color with different jumper materials, have you ever tried using solid core copper silver vs multi strand gauge, to see if the high frequencies improve? Currently my speaker wires are plugged into the HF with the multi-strand jumper and gauge going to the LF. Have you ever tried connecting the speaker wires to the LF terminals and using a solid core copper/silver jumper to the HF. What were your results?
