I’ve made many power cords and analog cables for myself over the years. This power cord is quite good. Is it as good as a AudioQuest Dragon power cord at $5400? I can’t say, I’ve never had one in my system. I suppose I should ask around to see if someone has a spare I can borrow.
To your question, it’s very good. It took a week of burn-in on the inlet to a power strip I use to power my workstation and another 2-3 days installed as the inlet to a P10 before I felt like it had settled in enough to start thinking about how it sounds. I compared it to a Cardas Clear Beyond XL power cord that I put together with new Furutech NCF connectors and it compares pretty favorably. I prefer the Cardas, but only slightly so. There’s a bit more body with the Cardas. It’s still in my main system, so I can’t be hating it 
I thought I’d give it a month or so for final judgement.
To purchase a new built 1M Cardas Clear Beyond XL = $2750
To build the cable I made = Approx $500
I suppose that tells the story from me. Is the Cardas cable $2200 better, especially if you have a real-world budget? No, it’s not that much better.
