I heard the ocos cable once about 3 years ago with a Naim system driving C1's. Ocos is more known for long speaker cable runs. Can't say it would be an upgrade but more of a sideways move. My preference for Dyn speakers is the Nordost series2 cables. I have the original Frey when I had my C1's and the Heimdall2 is better sounding cable IMO. If you can't demo cables consider the cable Company for they have a lending program.
