Interconnect between VTL tube pre and Bryston amp

I have a VTL 2.5 preamp and Bryston 3bst amp, linked with Cardas Cross. Tried a DH Labs Air Matrix and initially thought it improved alot, more detail. After putting the Cardas back in, I heard a more full bodied sound. What cable will give me more detail like the DH labs, but still sound full and musical as the Cardas?? Thanks for your time
