Recommendation for speaker wire upgrade


I am looking to upgrade my speaker wire on my home audio system and I wonder if anyone can offer advise?

I am currently using Audioquest Type 4 cable (externally bi-wired) between my McIntosh MA6600 amp and my B&W Nautilus 804 speakers (5.5 feet in length, with bare wire connections).

I am considering Kimber Kable 8TC or 4TC, or other brands in that price range. Some of these are available in internal bi-wire options, which I have no experience with, so I'm not sure how it compares with separate bi-wiring.

I appreciate any advise.

I am sold on the Harmonic Tech Pro 9 or Pro 11. The older versions are relatively inexpensive and sound great. Either would be a significant upgrade from the AQ.
Anti-Cable are surely great! .. but not on Hi Current SS amp
For my taste are one of the best choice on Tube Amps

IMHO
Come to your senses! A quick, inexpemsive trip to Home Depot for purchase of their 12 gauge speaker wire is needed to finally put your 'cable monster' to rest. Keep an open mind, please. It will change your audio life, forever.
My newest favorite speaker wire is Analysis Plus Oval, they easily replaced Kimber 4tc and 8tc feeding Green Mountain monitors w/a 2 channel McIntosh amp and also via monoblocks. The Plus Oval cable is a hollow braid like the 4tc/8tc with amazing speed/detail/precision but more neutral/natural sounding than the Kimbers. Anti-cables didn't work for me.

Absolutely agree - it will change your audio life forever (just not sure if for the better).
