@hilde45 -

     Back in March 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.

     Further: all of 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!

                                         Make that: perturbations (oops),

                                           AS IF that'll be the objection!
