@jrareform Could be, there is only one way to find out- get an XC and compare. Maybe I’ll give them a call in the next year, I had some other questions for them as well.

He has experienced greater success with XC from the wall to power conditioner
Ok, thanks for letting me know. It is a little confusing how they have an XC or "extra current" cable, so one thinks they should use it on the amplfier as well as the power conditioner, but then Shunyata suggest the NR "is excellent on amplifiers. "and yet they now have a QR cable which is "particularly suited for high powered amplifiers"
But this is right from Shunyata’s website:
SIGMA-X XC
SIGMA-X XC was designed specifically for use as a wall-connection power cord for use with Shunyata Research power distributors. Due to the extensive levels of filtering in Shunyata Research designed power distributors, NR filters are not needed at the wall connection. For use with other manufacturers power conditioners, the NR models will likely provide a performance benefit.
Bottom line is I can assure you my system doesn’t sound like the current is restricted in any way. But hey, not doubting the fact that maybe the XC is better.
