I’ve run a set of 10 gauge Duelund in my system, and my experience with them is similar to Mitch2’s. They have a tendency to run on the warmer end of the sound spectrum, but they’re not at all muddy or tubby assuming you pair them with the right connectors. I’ve had better results with rhodium plating rather than gold here.
I recently made a set for someone, and I think their comment sums up the Duelund cables rather nicely:
“People say tinned copper cables aren't the last word in detail, which may be true, but I think these could be a contender as the last word in musicality, for sure.”
All depends on what you’re looking to get out of your system.
