AUDIENCE AU24e vs CARDAS CLEAR for HEGEL/JA PULSAR

Hi All,
We're going to install a system for a client comprising the Hegel P20 preamp, H20 amp, HD25 DAC, and Joseph Audio Pulsars. The dilemma is that we're either going to use Audience AU24e speaker cable and balanced interconnects, or Cardas Clear (and/or Clear LIGHT) and will have absolutely no chance to audition either for system synergy given our time and budget constraints.

Has anyone had any experience with either in similar situations? And is the Cardas Clear LIGHT close to the same ballpark as the others? Can we mix and match Cardas Clear speaker cable and use the Clear LIGHT for interconnects?

Just to throw one more wrench in the works, our supplier can also provide us with Acoustic Zen or XLO, but since the client expressed a preference for the first two brands, those are our focus.

We only occasionally do audio installs in our design work, hence my questions.

Any advice would be very much appreciated! Thanks in advance.
