Synergistic Research Absolute Ref vs Elrod

Hey Guys,

anybody compare these to power cords yet? I currently have Elrod Sig 2 & 3's but I'm considering the Synergistic Absolute Ref. I just recently change all of my other cables to Synergistic.
Amps are ML 436's, processor is ML No.40, source is Ayre D-1x.

thanks,
