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!

Here's a crazy question... Might a power cable have more effect on the brightness than the speaker cables?
@marktomaras

That is a great question. From my experience a power cable can be very effective at taming brightness. I would start there before speakers cables. Your Cardas speaker cables are excellent.

Absolutely, not a crazy question at all.
Look for a used K-S Emotion cord.

Of course, it is possible that Wilson/ Devialet simply do not mate well too.

Good luck,

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. :) 

Best,
