Hi Robert. Thank you. A number of members requested bringing the thread back!
I’ve been troubleshooting one of my primary components which has made for a less than stable system. Once things stabilize, I will dig deeper into the questions you pose.
There was a significant difference between the ’base’ power cord I used first and the Triode Wire Labs ’Obsession’ PC.
Isolation will also reap rewards. I am currently using Herbie Giant Gliders under a TAOC platform. The Sorcer X4 sits on three SR MIG 2.0s in the "Pin Point Soundstage Configuration" on top of the TAOC platform. There is an upside, but less so than that with the Power Cable change.
I imagine your solution of Ingress Engineering RollerBlocks, a platform of slate (between), and then Springs (ala Geoff Kait) supporting the slate would be a smart one to try out.
Ozzy has reported favorably on this area as well.
Both the Power Cord and the Isolation / Resonance Control efforts result in the typical upsides associated with such changes (at least, based on my experiences with both over time and applications).
HOWEVER, AND IMPORTANTLY, the most positive result is to simply bring the Sorcer into one’s system (irrespective of power cables or isolation).
