Fadel Art Reference 1's competition

I recently switched my Acoustic Zen Matrix Reference Mk 1 interconnects for Fadel Art Reference One interconnects and the improvement was dramatic.

I almost bought the cables immediately, but then thought I ought to check out the competition first.

Any suggestions for similarly-priced interconnects? I was considering Siltech cables because my amp and pre-amp are Plinius products and use Siltech cabling internally...
