VAC / Wilson cables

Before year end I'll be replacing my VAC Ren 70/70 with Kevin's current iteration, the Phi 300. I've already upgraded from Wilson's Watt/Puppy 5 to Sophia 3. The cables, however, remain Transparent Reference.

I'm wondering, having upgraded at each end, if anyone has experience with a more current and improved speaker cable ? The pre-amp is Shindo's Giscours, fed by the Miyajima Kansui on a TW Limited table. Chamber, vocals, and keyboard is the diet.

Thanks,
