Klipsch KA-1000 or Bash 500s x2

[triode4]

I can buy either a used klipsch unit, or a new pair of Bash 500s amps (same price)for my Aura 1808 subs. Which would you buy and why?

this one, the THX one?
KA - 1000 - THX Amplifier | Klipsch

if so...100% the klipsch....

Yes, THX, I was thinking maybe 2 monoblock Bash might have and advantage.
