Nope!!!! Never happened to me. Over the years, every single time I've changed or upgraded a power cable, whether it be for an amp or any other component, I always heard some kind of change in their sound. Sometime the change in sound was subtle, and sometime it was more pronounced.
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?
