Mesch, are you able to see if your stock Nad power cable is 18 gauge? It's imprinted on the cable itself, along with various voltage and temperature ratings.
As for the PS Audio AC-5, here's round one, at about 87 hours in. In direct comparison with the 18 gauge stock power cord, I could only detect minor differences. This was at moderate volume levels with a mid grade Pioneer cd player as source.
Music was Dianna Krall's All For You cd, using a couple of the quieter tracks. I could hear the absence of a ringing type sound on the piano notes with the AC5. And it's not like with the stock cord I was hearing ringing noise, but just noticed none by comparison with the AC5. Also, the background was quieter. Inky black is the phrase people like to use I think, and it wasn't a huge difference by any means. Just notable.
I didn't have a lot of time, perhaps I'll dig deeper tomorrow. But frankly I'm not super impressed to be honest. My bias was to hear the angels singing, and they weren't even humming. I should note that I've read that the PS cables need 300 hours, though I have no idea if that's true. Just reporting the facts.
