Cardas hierarchy - older/newer - who has experience?

Greetings all -

I recently moved from cable agnostic/apathetic to cable enthusiast when I was loaned a pair of Cardas Neutral Reference interconnects. The improvement in sound was so unambiguous that my entire loom is now Cardas. Two pair of NR interconnects, plus NR speaker wires and a Clear 75ohm digital cable.

My system is sounding really good but I know I’m nowhere near reaching the full potential of the various Cardas cables. My question is directed to those who have experienced Cardas cables and have an informed opinion on the relative rankings between the older range (neutral ref, golden presence, golden ref) and the newer Clear-based ranges - Light, Sky, Cygnus, Reflection, etc.

Some of the newer range will plainly be upgrades. Others will be side-ways steps. I’d like to avoid those.

Thanks, in advance, for any help you can provide.

BTW, I have no interest in hearing from those who deny that cables make a difference. It is annoying and I don’t really understand why they do what they do, but they make a big and musically and sonically important contribution and make it easier to understand the performing musicians artistic intentions and choices.
