I wonder if you would know the difference not on an A/B test, but if your wife changed cords and you left your music room for a fair period of time. Say half an hour. Power cords are one of the things I've never gotten into. I do have a couple of upgraded cords. One I got when I traded a turntable for something and the guy threw in a thick pink power cord. I use that on my CD player and have no idea how it affects the sound. When I inherited my amp and some other cool things, I got a power cord and it's plugged into the amp. I never had interest in an A/B test because I already own them, and I think it's one of those things that you can hear when you're concentrating on an A/B test, but you'd have no idea if nobody told you they changed cords.
I am now listening to "Nardis" on "Cafe Blue" and the cymbals sound fantastic. I don't have the album to compare them to, but I felt that everything was there on the cymbals. Now that the Meitner is burned in a bit, it seems nothing is lacking to my ears. Give me an expensive dCS and I'd probably hear some differences. The guys at Stereophile who reviewed the MA3i did compare it to dCS 1/4 million dollar stack and said they could hear the difference, but once that comparison was over they were perfectly happy listening to the MA3i. Not the MA3, however.
