Digital Interconnect Issue

All right advice please (no $1K plus cable need apply)

Two step process:
Step 1
Looking to replace the Cardas lightning (1.5m) between transport and Audio Alchemy DTI Pro 32. Prefer (not a mandate) RCA one end BNC other (for the AA piece).

Step 2
Will get new transport and move to AES/EBU at each end. Current transport doesn't have AES/EBU out DTI has one in.

Input Please.

Take a look at the i2Digital interconnect.

Info located at

Went with a transport without the AES/EBU out.

NOW -- I'm on the Fence on Digital Cable (RCA's or RCA/BNC)

I've read good stuff about Bolder Cable. Anyone else out there got an opine?
