speaker cable question

I’d be inclined to go with the 6N zero crystal copper of the Acoustic Zen Hologram over the HT Pro cables.  I’m a very happy long-time AZ Satori double barrel speaker cable owner and couldn’t recommend their cables more highly.

From what I've read on various forums and a few audiophile friends that own them I'd agree, and give consideration to the Silversmith Fidelium speaker cables.

I have never heard harmonic technology speaker cables, but did have some interconnects that I liked. Maybe stay in the line? Love Shunyata power products, I have a Denali power conditioner and sigma power cord that is terrific. Haven’t heard a lot about their IC or speaker cables.  In the range you’re looking to spend there a lot of great options to explore. Classic speakers, BTW. 

I use a pair of Shunyata Venom cable on my turntable with excellent results.  It sounds much better than the $300.00 VPI branded cable I was using previously. 

I have the silversmith fideliums and am very happy with them in my system.
