Power Cord Burn-In

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.

You don't need to model "all facets of the musical experience and its impact on the human emotion" in order to model the effect a cable has on the signal passing through it. 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. There's a good deal of scientific work (outside your field, of course) on the latter question, Dr. Morris. I recommend that you familiarize yourself with it.

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.

Well of course it can't be correlated to measurements, since it happens inside your head. But you can't enjoy what you can't hear.

Actually, that's not true. You CAN enjoy what you can't hear. But in that case, your enjoyment is coming from something other than the sound of the component, so the technical parameters of the component are irrelevant.

When differences ARE audible, however, there is often a correlation between measurements and enjoyment.

Good, maybe we can use your expertise, once you give the idea of 'burning in' a chance.
