Yes my amp is a stereo Pass 250.8 and the manufacturer said don’t bother. I originally had a $500 going into the Pass and replaced it with the expensive cord. I don’t think my system is entry level. Maybe mid. I am going to place the expensive cord in various components such as my Dac and transport(both Ayon. I bought into the never ending advertising but people had positive things to say and I'm very happy having purchased them) to see if it makes a difference there. And though I may not have the most discerning of ears I like what the Shunyata sigma did for my ARC pre. Can I tell you what it did exactly? I don’t know really. But I liked it. I know lame. But maybe it gave it a bit more punch. It made me like it the component even more. I’m sorry but I’m not an experienced audio critic who can describe nuances. But with the expensive cord into the Pass as they say I felt(heard)nothing.
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?
