Directional interconnect cables

Another explaination of perceived directionality is the dielectric settling into a charge. If you reverse the connection then you'll hear an immediate deterioration that'll go away if your put them back like they were. However, if the dielectric charge is the cause, then if you leave it in the system long enough to "burn-in" again, then the preferable direction will reverse. If this is the explaination, then the arrows only serve to allow for consistent, repeatable connection.

This also can explain directionality in speaker cables and why elevating cables with insolators can improve sound.

I personally don't think that the copper crystals care at all which way the electrons flow. (In speaker cables they're going both ways, BTW). However, I have observed how changing the direction of a cable is heard.

Jeff Rowland told me and some others that he thinks that dielectric charges explains most of what we observe in equipment burn-in.

Mr D: Here's something that verifys part of what you said about the dielectric taking a charge, but that's not all there is to it. Read the section entitled, "Change a single piece of wire's direction and it is audible": (http://www.soundstage.com/maxdb/maxdb011999.htm) Also paragraph seven of this article is interesting: (http://www.soundstage.com/maxdb/maxdb101999.htm)

I generally agree with his comment:

"Reverse a wire and it takes a couple of days of use in the reversed direction for the wire to settle in and sound its best. This settling-in improvement is smaller in magnitude than the difference in sound from running the wire backwards, so you can tell immediately upon reversing a wire if it is in the best direction or not."

Except that I believe the whole thing can be explained by the dielectric charge. I "burn-in" my ICs and cables a couple of hundred hours and try to minimize the amount that I move them, so if I reverse one it's going to take more than a couple of days to recharge.

Just a theory. Unfortunately, most of this can't be measured, so no one that I know of has compared one directionality vs. another with sufficient burn-in between changing directions to neutralize the direction change.

If we believe it takes hundreds of hours for cables and ICs to perform at their potential, then any time we change direction we need to give the same amount of time before a comparison is valid, IMHO.

Wire is directional esp. solid core search some of Bob Crump's post here and else where

The experiment, performed with new(0 hrs) cables/interconnects, would be valid. Not hard to figure out. My theory concerning the chevron structure affecting the positive(compression generating) portion of the signal if a cable is reversed is based on the possibility of it acting as somewhat of a diode toward the signal. That would mean connected correctly, the positive(Compression) portion of the signal would pass unscathed/uncorrupted, the negative- less so. Perhaps I shouldn't have slept through so many sessions of Quantum Mechanics 101.
