Upgrade from base CURIOUS CABLE USB?

Wondering if my CURIOS CABLE USB should be my next upgrade. Looking at David Laboga, FTA and SABLON based on reviews and customer feedback.  Here’s my system:

Pathos InPol Heritage Integrated

Tannoy Kensington GRs

REL S/812

Innuos Zenith MK3 

PhoenixNET/PhoenixUSB

CHORD M Scaler/DAVE/Sean Jacobs DC4 ARC6 LPS

Cables mostly Transparent Gen 5 Ultra or Reference 

TIA and HNY!
