Length of speaker cables

@kozka, OK then, if you wish to be so picky about someone's choice of words for a description then I will restate if, just for you.

"You will be very pleased with the way these cables carry an electrical current".

This really doesn't seem to express much in the way of emotion or musical pleasure.  At least, not to me.  But if that makes you happy I am glad to have provided the adjustment.  Please do have a safe and healthy Memorial Holiday.

You got me on that one.  Please excuse the error.

Looking back to yesterday, I hope that everyone had a safe and healthy Labor Day Holiday.
Looking back a few months, I hope you enjoyed the Memorial Day Holiday, too.

First of all, the quote from Richard Vandersteen is absolutely correct. This is my experience. I went from 15' to 8' of the same Rocket 88 speaker cable and found a slight, but noticeable difference in details against a black background.  Psychoacoustics?  Possibly... But the real change came from replacing Rocket 88 and moving up to William Tell ZERO in 8' length.  That opened everything up, considerably.  eagleeye7 describes it exactly correct, just above.
It's an expensive upgrade, but if you are placing plenty of your money into mono block amplifiers than don't stop there. Feed them the signal that will yield the best results.  This also includes high quality power cables, if you don't already have them.  Note; William Tell ZERO is a full-range speaker cable.  If you are running bi-wire than you would need to buy the bi-wire combo setup.  It's very expensive.  I went with the full-range William Tell ZERO after coming from my bi-wire Rocket 88.  Man, it is awesome!
Best to you. 

@steven0713,

CONGRATULATIONS!!!

You will be very pleased with the performance of those cables.  It's an end-game in the category.  They are keepers for many years to come.
Enjoy...

@steven0713,

Just one more comment, as a way of making an analogy.

Going from the Rocket 88 to William Tell Zero is analogous to looking at beautiful scenery through a highly transparent and very clean pane of glass.  And then, opening the window.
Enjoy!
