Power cable

@soix overall I would say something that would bring everything together more. My GIK panels came in a few weeks ago. I do like that they have done and I have more to get, taking in slow and methodical. I do wish the quality of the GIK were better but they do serve a purpose. I wish I had the time to make them with my buddy. The quality would be much better. 

I use Cerious Technologies with Pass, including X250.8...3 models depending on what you want to spend...all worth the increase in price...

Don't waste your money.  Put it into room conditioning.  A good quality amp converts AC to DC, rectifies it, filters it and regulates it.  It could care less about the 6' to your outlet, the distance to your electrical panel, or the run up to the transformer on your power line.

Would you say you’re looking for more detail or air in the treble, more tonal richness or color, etc.?  Or, put another way, what to you seems not as together as you’d like currently?

Here’s a review of several outlets I found interesting as they’re compared directly to each other (and includes the GTX-D).  I came away intrigued by the Cruzefirst Maestro outlet for its design, sound characteristics, and value.

Here’s another review that had similar findings…

FWIW. 

@ghdprentice at the time I bought my Niagara 1200 they told me those would be overkill for it. I went with the monsoon cable, it’s a good cable overall but I’m curious what’s out there and power cables seem to have great effect…. Depends who you ask. Haha
