I am completely re-doing the AC distribution and grounding for my system with a combination of commercial and DIY components. I’m going to initially focus on EMI/RFI reduction as I can measure it directly and also look for it as artifacts in the system output. I will be looking for 60 Hz and it’s harmonics as intermodulation products on the desired audio signal. By using my Audio Precision System One DSP capability I can measure well below the broadband noise floor. I’ll need to do an MSA to ensure I can get repeatable results.
By using DOE I will speed up the process and see how different cords and filters on power amplifiers and signal sources impact the measured end result at the speaker input.
As I learn more and perfect my measurement system I’ll look at higher end power cords. I’m impressed with what I’m hearing so far, so look forward to trying some higher end cables.

Cool, Tom! Love to hear you're doing an MSA and DOE! Good on 'ya, mate!
