Length of speaker cables

@mammothguy54,
+1
Though the OP doesn't have to go as far up the AQ chain to achieve higher resolution, I would personally opt for the William Tell's, as it would be the end of a chase.
Don't believe me? 
PM ctsooner, or audioconnection (John Rutan)- the latter can give you the best info on cables-PERIOD

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.
