Length of speaker cables


I just went from 2 channel amp to mono blocks. Is it important that I stop using 4 meter audio quest rocket 88 and downsize to 6 ft? Will there be an audible improvement?

I am using Kimber Summit Series  Bifocal XL 2.0 Meters each terminated with WBT610 CU Banana Connectors. Part #  BFXL2.0MP0610Cu
Between my monoblocks and my speakers which accept this connector and they split the Hi Frequency & Lo Frequency.  Extremely nice.

Nearly any length you wish....I wouldn't make mine any longer.
Best, Steve
Thanks for all the help. Now waiting anxiously for delivery of William Tell Zeroes 
@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...
@OP,
No reason to be 'anxiously waiting'.
Those cables are going to 'rock your world'.
They did to mine.
Whatever Garth Powell is doing, you can be sure it will be for the positive.

@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!
