Over the past few months, as I improved all aspects of the sound, I noticed it getting brighter and too analytical. I posed the question somewhere on this forum and was pointed at Duelund wiring. It’s very affordable, and won’t need plugs or jumpers, just bare wire, so easy to try.
I swapped out my TelluriumQ Ultra Black II speaker cable for Duelund Dual DCA12GA and am loving it. Admittedly, the TQ did excel in some areas, but crucially tone and musicality is far better, and at a tenth of the price. Overall, it’s a darker, warmer more intimate sound.
If you have a USB cable in your path, then I would recommend any of the David Laboga cables. Purist cables are also reportedly warm, especially the ones with fluid shielding (Neptune, Poseiden).
Otherwise, I’m mostly "there", though am still aware of too much sibilance from female voices. This improves however when I close the curtains (drapes), so I suspect the room is mostly at fault - hard floor, leather seating, windows etc. A family room with no scope for panels, diffusers and traps.
