Speaker Cables - Revelation, Elrod, Violin or FIM?

Hi Folks:
I've been upgrading my system of late, and latest step is now speaker cables. I'm keen to get recommendations on some good high end cables to compliment my system which includes JM Lab Diva Utopia Be, KR Audio tube amps, Supratek Syrah pre, Northstar digital rig and Teres/ZYX analog rig with an air-bearing tonearm.

So far I'm narrowed my choice of speaker down to a few contenders on the used market - Virtual Dynamics Revelation, Concierto Violin, Elrod or FIM/CRL Gold. I've owned the FIM Gold before, and really liked it but would be up for trying something new. I'm currently using a pair of kit cables from the 47 Labs OTA Sakura cable kit. They are simple copper wires which are just .4mm thick. I think I need something more beefy ;-)

Anyway, I'd value advice, particularly from folks whove heard two or more of the cables above, or would welcome recommendations on other cables. I'm keen to spend less than $1,000 but can stretch to more $$ for the Revalation if they truly are better than the others. I'm hoping for these speaker cables to be my last (famous last words).

Thanks!
