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?

Fifteen years ago I spent $10k on amplifiers and the dealer loaned me a $1k power cord and a $4k power cord. I conducted a single blind study with a 3 x 2 experimental design (stock pc, $1k pc, $4k pc) x (wall power with hospital grade connectors, isolation transformer with hospital grade connectors). Results were clear: with wall power, the system (analogue, ESL) sounded better with more expensive cords. With the isolation transformer all cords sounded the same. Conclusion: more expensive cords can reduce electrical grunge on the line, which can affect even a good amplifier. I infer that if your power is already pretty clean, expensive cords may not do much for you. YMMV |
Oh looky, earlflynn/skypunk/jerryg123/etc. etc. is back! He’s now @coleyounger1896. Honestly man, is your life so devoid of interest you have to continuously get banned and come back? Seriously, seek professional help. |
I just purchased some entry level power cords from PS Audio for my sources and pre. Upgraded the receptacle and then sourced good parts and assemble my own amplifier Power Cord. I didn’t even try to figure out if it made a difference. If you have not assemble you own PC I suggest giving it a whirl. Its fun and an easy part of the hobby. If I get motivated I want to make one for my DAC.
If you go over to the Cables section those guys will stupefy you with suggestions on what to us for construction. |
