Do I need higher quality power cords?

Wow, inadequate power supplies in my equipment. Shadorne, have you, or have you not, tried a different cord on any of your components ? You must have the only equipment who's power supplies are not woefully inadequate. @spotcheckbilly, thank you for coming to the party. 10 posts. I am quite sure your numbers will be in the hundreds in no time. Enjoy ! MrD. FWIW, this is always fun.

Sounds like a case of inflated ego mixed with expectation bias, nothing more and nothing less.

And you base this opinion stated as fact on ... your own ego and expectation bias, perhaps?

I'm sure Audio Research will be glad to know that their Reference 10 preamp has an inadequate power supply since it responds dramatically to different power cords.  Perhaps we should petition the company to fire the designers.  Where do people come up with such nonsense?

Other high end amp manu-fractures will be very sad to hear this news. You know, Lamm, DartZeel, Classe, Parasound, Gamut, McIntosh, Mark Levinson, Conrad Johnson, Krell and Pass.

@geoffkait that is just the tip of the iceberg. Besides, shadorne must know something so many manufacturers have missed in their designs. And he has a follower.
