Speaker Cable Upgrade... Advice Please


My current cables are Cardas Cross.  My speakers are Wilson Sophia 2.  I just changed electronics from Audio Research tubes, PS Audio DAC, and Whest Phonostage to the Devialet Expert 220 Pro.  The sound is a bit more bright and forward than with the previous gear.  I am happy overall, but I would like to tame it a little.  I am considering an upgrade to the next price category in speaker cables.  $2-3k retail new for a 2.5 meter pair.  Any suggestions for a cable that will work well with my gear?  Any thoughts on Nordost in that price range?  Perhaps Heimdall 2?

The brands that have peaked my interest are Purist, Verastarr, Nordost, and Cardas.

thanks!

So, my previous reply was predicated on the understanding that your room acoustics were already well taken care of? If not, absolutely seek out GIK Acoustics first. 

In general, brightness can also be helped by adding floor coverings and absorbers even between and behind the speakers. I know it sounds crazy, but try throwing some blankets and pillows around as a free experiment, then come back and tell me I'm goofy. :)

Wireworld.  Pretty dark cables

Dark? What did you have them paired with? Thanks.
I haven't found my wireworld cables to be dark. But that is just me and I am only one person. They do seem like they have  solid images or structure in their presentation, they are not fuzzy like some cables, yet not tipped up much, maybe not at all. I say that 'not tipped up much'  because I think so much stuff is tipped up in the high frequencies.
I have found the Audience PowerChord and PS Audio PC’s to have a smooth and realistic top-end. They both present a laid-back image with excellent soundstaging. You can gain more detail as you move up the PowerChord line.
The Cardas Golden cables will have rolled-off highs, with a presentation that is more forward. The Clear line is more open, transparent and with good detail and texture.

Budget cables; Pangea, nice smooth top-end and laid-back, but not a detailed cable. Cullen is very smooth on top, with good soundstaging. Signal Cable, transparent but very extended and detailed.
