What cable is best?

Look at Furutech and Purist for a big upgrade in sound.

Which cables would be better? The DH Lab Redwave with the better connectors or the better Corona DH Lab cable with the lesser quality but still decent Watgate Blue Dot gold connectors?

That cable is best which sounds the best.
What? You think its all about connectors? Beware the narrative.

The Corona is wound in a counter-spiral. No mention of that with the Red Wave cord.

Well you'll have both cords in house to why not compare and tell us? Some folks think the connectors matter more others the wire. Unless you want to get multiple versions of the same cable with different connectors don't worry about it just pick what sounds best to you.

I own both versions. They're very close, although the Corona is still very new. When I bought the Red Wave a year or so ago, I was amazed.

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.

I would say that the better cable would be component and system dependent.

So much of this hobby is system dependent and personal preference, go with what sounds better to you. As for my take on cables in general, the materials in the cable and the geometry used dictates what the cable will sound like. Connectors, very little.

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.

yes, connectors do make a difference especially if the two in comparison are built differently and use different plating, many run of the mill connectors are very similar and uses gold plating, therefore they sound very similar.
I'm a firm believer in the cable itself....the conductor, dielectric, and geometry. To a certain degree, you can tailor the sound you want by the ingredient and geometry used in the cable. This is from experience. 

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