Acoustic Zen Matrix Reference MkII.
Harmonic Tech Pro-Silway MkIII

On the cheaper side, don't laugh, but the BlueJeans XLR interconnects are really, really good. 30 days return too, so you can even send them back when you're done!

How about making your own from Mogami 2534 wire and Neutrik connectors.

I bought 80 feet of Mogami and four Neutrik connectors for $80 from Markertek.com.
