Anyone have the Answer?

They make products to measure your ac lines for sure but i can tell you that a good conditioner will improve the sound of your system whether the line is a good one or a noisy one and you do not have to spend thousands to hear the difference.

First things , I had installed dedicated 20:amp lines awg 10
with and this is key 4 wire ,dual ground one common the other a insulated isolated ground with copper gold plated outlets .
a night and day difference in detail as well as silence. That was the
best value per $$ spent in Audio ,and I hav3 had a friends AQ5000
line conditioner ,slightly better then my line by maybe 2-3% 
if it is a great recording .

What I been saying for years, the single most cost-effective power improvement is to replace the standard outlet to outlet circuit with a dedicated line. The details of wire, gauge, etc are very minor compared to this one thing.

Here's your answer. I believe a balanced power unit makes sense. I was able to obtain mine for under $1K. My system is completely black.

There was a Shunyata video where they identified and demonstrated some sort of device they had acquired that demonstrably measured line interference both before and after they used their line noise reduction equipment on a circuit. It shouldn’t be too hard to find that video on youtube.

Or give them a call and I’m sure they could point you to the video, or better, even let you talk to the equipment designer using it in the video. They are quite accommodating when you call, and should be able to direct you to the person that could answer you question
