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?
@eurorack of course if you change from a substandard, “crud” power cord to something that’s half decent you should notice a difference. That’s obvious. Crap is gonna limit anything in this world - power cords or not. What we discussing in this thread is if there’s a difference between a $100 power cord and a $500 power cord and a $4000 power cord.
That’s very different from the experience and situation you are referring to, I think. |
I'm fairly certain; very little critical audio listening goes on in fighter planes. However: here's something that NASA selected, to conduct power, for their portable LASERs.

@rodman99999 - this is exactly what I mean. There is little critical audio listening in the fighter plane, but i am sure quality cables are selected to deliver power in environment full of RF interference and when performance may literally mean life or death. They would perform well in a less hostile conditions :-)

New video -- 2 Power cords sound test 1) click 3:51. This opens YT window. 2) In YT, make a small YT window (narrow & tall, right half screen) to see the video screen and 2 time stamps (3:51, 9:37 in description) are in the same screen. Just relax and feel what comes to your ears when you click. ** Please visit my room (#272) at THE Show 2024, OC. Costa Mesa audio show on June 7-9. Alex/WTA |
No doubt: they're selected to dependably deliver DC voltages, under those conditions. Personally: power cables designed to conduct (perhaps: purify) AC voltages, or: ICs designed for the highly complex musical signals I enjoy, are my preference. When it comes to performance, in life and death situations; it's been my experience: firearms are much more dependable. Out of curiosity: what brand of fighter jet cabling have you found to use in your system? How did you do your research, or: have you schooling in Avionics? |
