The standard cable is nothing special compared to Linum SuperBax, PW Saladin+, DD Air Nyx, Whiplash TwAu 8, Whiplash TwAg, Cardas Clear Light, Effect Audio Cleo.Rather not true in case of FIR's stock cables.
Scorpion is quite good, better with Xe6 than i.e. Forza Hybrid, PW No.10 or Dunu Hulk.
Around $1000 - the difference could be audible - LL Venom, Erua Tawa.
But below it would require a lot of hunting to find a better one than Scorpion.
All of these cables are under $1,000 and aren't even new, they've been out for a few years.
But maybe I just haven't come across worse cables, who knows.
