Speaker cables for Ayre gear with KEF speakers

I suggest you consider Silversmith Fidelium.  They resulted in a major upgrade to sound quality with my Odyssey Kismet monobloc amps and Fyne F-702 speakers.  The company offers a trial period, I believe.

I used to use Transparent Ultra cables with my Ayre amp and CD player. I have now changed to XLO speaker cables and Ansuz balanced interconnects with my current Ayre gear (VX5-Twenty amp and QX5-Twenty streamer/DAC). I never liked Cardas with my systems but that’s just my idiosyncrasy I guess. 

I have a pair of Cardas Clear Sky x4 that I'm willing to sell. 2m. PM if interested. 

For what it is worth, I run a 3-m pair of second-hand QED 76-strand, silver-plated copper cables from my Krell amplifier into KEF Reference 1 speakers. So far, I have felt no urge to bi-wire or spend more.  The Reference 1 certainly benefits from high-current amplification

I know that KEF uses wire from Chord inside the Reference & Blade speakers. No clue what actual gauge or construction.
