ABX testing with AQ Dragon power cords

                                  Now: some for something different:

     Back in March 2022: a thread about power cords and break/burn-in was started.

     I hate to type, so: I'm going to copy/paste some of my speculations.

     That a highly complex musical signal, MIGHT affect Poynting vectors and signal speeds*, in interconnects, in a much more profound manner than a simple AC (ie: a fixed 60/50 Hz) signal, in a PC, seems likely (at least) to me, as; in EVERY formula regarding *those two, a signal's frequency (frequencies) always factors in greatly.

     Further: the above and what I'll c/p (seems to me) lends credence to how the application of a stronger, DC voltage/field, outside a dielectric (ala Synergistic MPC and Audioquest DBS systems), might stabilize those vectors and signal speeds, PERHAPS eliminating some time smear and, "burn-in".

                                                                                         Happy listening! 

@dwcda -

 Yet still you’re pissed off at me for documenting these experiences.

                                          I am?

                                           🤣

When your proof relies on such words as speculations,  seems likely (at least to me), lends credence, I would hope it's a given, just seems to me, not a big stretch to believe, I haven't tested this, it wouldn't surprise me.. you know you're speaking about subjective opinion and not substantive facts.

I can only tell you my history with powerlines and cables.  When I started on my journey of improving it, I had a dedicated 20A  line installed by a pro.  Not a great upgrade by itself, so I bought new powercords for all electronics which were highly touted by a audiopphile mag,  After a month or so there still was very little to no difference.  Hmm.  So I bought a audiophile rated wall outlet and in the process of taking out the old one, I noticed it was a lightweight $2 or so 15A outlet, stamped metal etc.  Afterward,  I listened to see the improvement and BOOM!  Music in living color literally jumped out of the speakers.  Moral of the story is that this was the weakest link in the powerline.  So that's what you should look for. 

I am?

                   Thank you for telling me how I feel!       

The shouting caps and repeated reference to the Church of Naysayers were my clues. That's not typically how calm differences of opinion are discussed.
