Elrod vs electra glide?

How do power cables from these two company different from each other? I am interested in the EPS3 signature or non-signature vs mini khan or ultra khan. What improvement can i expect? I am planning on using it with Pass X250.5 (Golen pc) amp & Classe CA2200 amp (low end Synergistic PC).

I have a dedicated line 15amps.

Thanks in advance.
