Moved Audio Quest cable to my DAC. WOW

"I have always been skeptical due to my electrical engineering background."...he,he.😉

Try a DC Block on your amp instead:

I too have an engineering background. I also have degrees in Physics and Nuclear Engineering. I enjoy seeing laypeople laugh at engineers.

True scientists are indeed skeptical. Google educated scientists jump on simple concepts and get it wrong a lot.

An engineer will continue to pursue improvements with an open mind as @vanson1 has.

I think the concept that is most often missed evaluating power cords is to look at the steady state/DC equivalent current requirements rather than the much higher currents that are seen for very very short times to support dynamics.

As for all the high-dollar cables mentioned above, they engineering behind them is quite well understood. It is in the marketing area where most of these manufacturers excel.

well educated, intellectually curious and honest scientists understand and keep the limits of science, what science can/cannot explain or predict, at front of mind

and then there is the ol' marketing department, baiting and casting hooks into wallets...
