You're probably responding to some of my previous posts. I've had the Lazuli Reference and the Lazuli Ultra, sold them both, and the WireWorld Nano-Platinum Eclipse is my fave.
I've been listening to the Norne Silvergarde S4 for the last couple months
Joe was the one who turned me on the WireWorld, so, once again, thanks Joe!
FWIW, the Ultra has very similar physical properties to the Reference when held in the hand (thickness, stiffness, weight, etc).
I wouldn't put too much stock in price as an indicator or predictor of quality. IMO, system synergy and personal preference play the biggest role by a good margin.

Now that I'm reflecting on the various cables I've listened to the Utopia with at length, I'd say the most important starting point before considering any other qualities is whether you like the resulting tonality of a given cable. If the tonal balance isn't to a person's liking, none of the other qualities will matter, long-term. For me personally, I've found it very hard to predict if I'll like the tonality of a given cable without trying it out concretely, and at length. Here are some quick subjective opinions:
The Lazuli Reference does pair well with the Utopia, tonality-wise, and is a pretty safe choice. I also really liked the WyWires Red with the Utopia for the same reason.
I found the WyWires Platinum to be a little too bright and intense, but very fast-sounding. But that was with a version of my system a few iterations past, which itself was too bright.
I found the Lazuli Ultra to sound raised in the upper-midrange, which I found a little odd-sounding. It has other qualities which were very lovely, but that tonality was a dealbreaker for me.
The Norne Silvergarde S4 is the last cable I listened to at length. It has an emphasis in the midrange-to-upper-mids which is exciting but long-term isn't my preference. Lots of detail and nice sense of decay, though. I'm still debating whether I want to keep it around for added variation, or not.
But yea, the WireWorld Nano-Platinum Eclipse is my favorite over all the above. The resulting midrange is very even and makes everything sound more realistic to my ears. Treble is not hot. Bass is fastest and deepest I've heard. It is, however, discontinued.
