@clearthinker Shunyata Research’s website discusses each design aspect that resulted in the current line of power cables they offer. Here is an excerpt describing the noise reduction capabilities included in the NR cables:
"CCI filters have the unique ability to reduce component-generated power line noise without inhibiting DTC (dynamic transient current delivery). This unique filter element prevents power line noise from one component contaminating the other adjacent electronic components. Shunyata Research’s CCI filter modules consist of proprietary multi-stage filters that reduce power supply-generated noise without the use of heavy transformers, coils or large capacitors."
Elsewhere on the site they specify a NR capacity of >12dB per cable. I added one cable at a time as I was skeptical about the NR claims. Hearing details deeper into the soundstage and being able to discern minute errant sounds in live recordings especially, added a new realization of realism to the music that made the overall investment worth it to me. I have had them in the system for about 9 months and have never looked back. YMMV but my system and my ear/brain interface say Yes to Caelin Gabriel’s offerings.
