REL Strata III owners.....

I just added a REL Strata III to go with Magnepan 1.6's and can't believe the positive difference it makes. Any Strata III owner's out there that have tried different neutrik speakon cable's, such as Signal Cable or Synergistic Research, instead of the factory neutrik cable and with what results? Thanks in advance!
I am using Signal Cable with my Srata II and Merlin MS-MX speakers. Very happy with the cable,
Hey Bryan....thx. Did you compare the factory cable to the Signal Cable and with what results?
