Odd length speaker cables

I counter-balance this by advancing the 16ft side speaker
about a foot in front, and the image centers beautifully.

How can you possibly relate these? Moving the speaker 1foot
changes the arrival time (at the ear) by a bit less than
1millisecond. Changing the cable length by 7inches changes
the arrival time by about 0.0006microseconds.

Your dealer is wrong.
The better the equipment the more you will notice the
difference in the uneven cable length.

Well, that assertion should settle it for once and all. All
you have to do is be able to accept it.

I can't.

Sorry, Sonicbeauty, but you did relate these two variables in your statement and there is no scientific justification for it.

Since you assert that you can fix the problem by moving the speaker a bit, you are extremely lucky or it is the result of something else.

Of course.  :-)

The difference in loudness is equally trivial and inaudible but I guess you can convince yourself of anything if you try.

BTW, I see there was a typo in my original post.  It should read:
