Power Cord Burn-In

Dr.
"..we have greatly expanded the regimes in which
one can accurately model electron transport in cables to
very high order.."

Still an approximation even by your own words.

Dr., are your comments based on your listening experience or just theory? I am also a Physicist but I have learned not to take myself too seriously as you obviously do. Did you just receive your Ph.D.? I have learned over the last 35 years in audio to rely more on my "EARS" than Maxwell’s equations, etc. Stop being so pompous.

Dr., I also have a doctorate in physics from a "Prestigious" university. I did say " Maxwell's equation, etc." My research was in Quantum Fluids. I found it unusual for someone to sign his or her post:

"Dr. Gregory Greenman
Physicist"

My main point is that measurement instruments are "accurate" provided you have defined "exactly" what you are trying to measure and the instrument has been precisely calibrated. Modeling of all facets of the musical experience and its impact on the human emotion is an inexact science. Mathematical equations are for the most part models of the phenomena occurring in nature. They are merely approximations, and are "exact" only under very restricted conditions.

Bomarc:

".....Of course, once you know the effect the cable has on the signal, you also need to know whether that effect is audible to humans..."

I agree with the above but not the sarcasm. I am aware of the existence of "a good deal of scientific work" and have read quite a few of the papers. My point is still germane to this discussion: listening pleasure is the ultimate objective (I hope). In many instances this enjoyment cannot be correlated with the measurement of specific technical parameters.
