OK. So, I started out with a long, old, Belden Gold USB cable. It was serviceable for sure. Nothing to write home about, but no glaring issues either. A few months ago I bought a Pangea SE USB cable. It was a nice improvement over the Belden especially in detail and focus. With that said, I don't think the Pangea is the most neutral USB cable. The top end is slightly emphasized so leading edges stand out versus naturally blending with the musical portrait. I guess refinement is what it lacks a bit of. Overall, for ~$50 it is a REALLY nice cable and well constructed. Recently I got a lightly used Curious Cables USB. It is indeed the best I've tried so far and likely the last USB cable I'll buy for a very long time. It is not cheap and cheerful, but what it revealed to me is that I was missing a bit of space, bloom, decay and again, refinement, with the Pangea. The Curious Cable is overall just more natural and neutral. This is to be expected with a much more expensive, bespoke, cable. But for $50 the Pangea is no slouch and really quite impressive. I highly recommend it as a meaningful step up from Belden Gold, which I think is the cheep and cheerful USB "standard."
