Are manufacturer AC cables good enough?

Repeating roman precept of law in a dialogue between deafs dont make any progress possible...

Experiments dont  necessarily need an evidence to begin with....Only dialogue between donkeys or lawyers and accountants need this kind of evidence called blinders or rules, pick the one you are pleased with....

"...can current be distorted..."

Yes it can. Stand in the river and watch.

Noone said blind tests are irrelevant. You’re putting words in my mouth. What I said is they don’t mean anything. They only mean something when there is a preponderance of evidence from many tests, independent from each other. 

Glubson is on roll today. Unfortunately for the rest of us. 😬 Talk to the hand! 🖐

That’s essentially true. And that’s why - if you’re among those who believe blind testing is the best way to evaluate an audio component - the only single blind test results that are really important are the results of your own test.

It’s really difficult to take seriously those who incessantly call for blind testing to be done by others.
