Synergistic Research Apex vs. Cardas Clear SW

Has anyone compared Synergistic Research Apex SW vs. Cardas Clear or Cardas Clear Beyond Speaker Wire. I'm running McIntosh C2300 preamp and MC402 amp into Dynaudio Confidence 1 speakers. Thanks.
This is when The Cable Company's lending library becomes valuable.
I suggest trying the Von Schweikert Signature speaker cables. They are made in conjunction with Delphi Aerospace.

In my system they bested the Synergistic Research. In addition to Apex you have to buy the $400 Galileo MPC's.

I can provide more feedback if you like.
