I never put much stock into power cabling as I never had a system able to reflect the improvements they may have provided.
Now I have a system that is super revealing and I have spent the last 4 months auditioning and running experiments with a multitude of cables:
JPS Aluminata
Elrod EPS-2, -3, -3Sig
Hijiri Nogamo
Harmonix XDC Studio Master
Harmonix XDC - 350 Studio Master
Harmonix XDC2
Sablon Robusto
Signal Cable ?
NRG Custom The Five
ED 316
Kaplan HE MKII
Puritan standard line
and a Masterbuilt Reference is on the way.
It's crazy how the bass can be adjusted up or down and the sibilance can be tamed (or worsened), or you can really blur the sound with the wrong cable.
