Interesting observations. I’m burning in a FP-S022N cable right now.
I picked FI-28(G) IEC and FI-50 (G) connectors. I had read the cable might be a bit bass shy, and thought I’d go for gold connectors instead of rhodium.
I’m going to try this on my DAC. I tried a Black Mamba V2 on it, and it’s very, very, good. Very neutral cable, good details, and silky smooth. However, a bit bass shy for me. I like my bass just a bit plummy.
Maybe I’ll try to swap the connectors around? Also Have some MPS Hercules connectors on order and may try those, too.
