Speaker cable upgrade

Some of the usual suspects will howl and bark. If it makes sense to you, though, then it should not matter one bit to anyone else but you and your partner, as the case may be. Only caveat: make sure to audition first!!!
Enjoy the music.

Don't forget to try Kimber's Monocle XL and Wireworld's Eclipse Series in your auditions. Either one will present a very balanced(with regards to frequency), open and uncolored signal to your speakers. CRITICAL: Be certain they(or any others you try) have been burned-in for a couple hundred hours before deciding if you like them.

Doesn't make sense to me for many reasons but it's not my money your spending. Karefeld nailed it.

If you decide to experiment with cables, I have had much success with Anti-Cables. They are very cheap, but very, very good in my system. All cables sound different, so you should listen to the various products. I personally didn't think Kimber Monocle was so exceptional...at least in my system. You really want a flat (frequency ) cable..one that presents real music in real time. There are many cables out there that exaggerate various characteristics... that will ultimately be unsatisfactory and you will be looking to change the cables again soon.

For that amount you can upgrade another component(s) in your system.

It would have a far more significant effect than $8500 speaker cables.

IMO
