Cardas Clear Beyond XL PC vs The Rest

Hello all,

I'm in need of an additional PC, and I am intrigued by Cardas. I currently have Audioquest Hurricanes and Audience Front Row. There seems to be very little about the Cardas XL in search engines or reviews, and very few are listed for sale (Are they so good that no one wants to part, or are people not buying?). I would appreciate any input you may share (or any other recommendations). This cable will power my Innuos Pulse. 

Thanks!
