yoby,
Thank you for comments, I do appreciate it.
No, at this point I am not using the Matrix power cords. My DIY power cords were quite labor intensive to build and I used some very premium wire (Furutech DPS-4) and Furutech’s $$$ Nano connectors.
Funny, you should ask that question about the Sonic Tonic. I haven’t liked the Tonics with interconnects.
With the Graphene Extreme interconnects the Sonic Tonic was too much. That is, the music sounded "aggressive". But now with the Matrix the Sonic Tonic seems (thus far) to add dynamics to the sound quality.
I think its because the Matrix XLR’s are using the Shadow connectors and this may tame the aggressiveness out of the Sonic Tonic. But, I have changed my mind several times on the Sonic Tonic placement, so time will tell whether I keep them on the interconnects.
One place they work great for sure is on the incoming main AC lines and on the audio dedicated breakers inside the circuit breaker box. And I also like them on HDMI connectors.
