All this demonstrates is that you are a sensible person who doesn’t automatically assume that because he paid $500 for a power cord it sounds better. Congratulations on having such good sense. The power cord mania is pure nonsense. I bought fancy power cords for all my components a few years ago and ended up selling them all because they made no difference in sound. They looked great, but I wasn’t about to turn my units backwards so I could admire them.
New expensive power cord for amp and no change in sound?
I bought new an expensive(for me) well known and reviewed power cord for my very good amp and plugged it directly onto the wall socket. After a couple of weeks of daily use I hear no change in the sound quality from a $500 cord. I don’t want to name it for fear of getting my thread deleted. You would know it or at least be aware of the company. Did I throw away several thousand dollars? Before I get the snake oil answer I want to let you know that I bought an upgraded cord for my pre as suggested by the pre’s manufacturer and am pleased with the results.
I guess for full disclosure the amp’s manufacturer said don’t bother. But I had had good luck with the pre so I thought it would be a good idea.
Anybody else have this happen to them?
