I haven’t done a lot of cable swapping, but I have heard enough to have a general impression of certain brands. I like Audio Note cables—warm, harmonically rich and smooth sounding. To get the kind of clarity you seem to want, their silver cables might do the trick, but the price is quite high even if you can find used cables. I use both their interconnects and speaker cables.
Another brand with a similarly rich sound is Acrolink. There copper cables have a bit more top end than Audio Note.
Of the brands you listed, I have heard, and like, Snake River.
For speaker cables, the Silversmith Fidelium cables sound very promising—detailed, but not harsh or thin sounding.
