Alternate interconnect to Cardas Neutral Reference

I'm currently using Cardas Neutral References in my system and I'm finding them kind of dull and unemphasizing. They do have a nice warm and neutral sound to them. However, I'm looking for an interconnect that has more definition, clarity and is musical. My current set-up is:

Conrad Johnson MV-60 amp
Conrad Johnson Premier 16LS pre
Musical Fidelity Tri-Vista SACD
Dynaudio Special 25's
PS Audio P500 A/C conditioner

So far I've been considering Audience AU24, or Audioquest Cheetah. I'm open to suggestions or recommendations...
