What cable is best?

Both cables are nice. The Corona is faster and more detailed where the Redwave is warmer and sweeter sounding. I would say that the better cable would be component and system dependent. On my warmer Moon 430HA the Corona but on my Pass Labs X1 the Redwave. The higher end connectors make a big difference. I have Redwave cable with Blue Dot Watgate same as Corona cables and I have Redwave with FI-50 Furutech connectors.

scar972 I disagree. I find by experience that connectors make as much a difference as the core cable itself. I’ve done the experimentation and find connectors add a characteristic to the sound of the cable as the cable itself.

The  Corona cable is better in my system regardless the connectors which do make a difference.
