Interconnects for Pass Labs X260.8

What balanced interconnects are you using with your X260.8 or X350.8?

Looking to potentially move on from my Acoustic Zen Absolute Copper XLRs. While they worked wonderfully with lower power amps I had with their plump bass, including the XA30.8, I find them (suspicion at this point) to be too much of a good thing with the X260.8.
What ICs would have the same natural tone but have better clarity and faster bass?

Gear (in my profile as well):

Bricasti M3, Wilson Sabrina, Pass XP22 preamp, X260.8 amps, Audience AU24SX speaker cables. Amps plugged into outlet on a 20A dedicated circuit.

Thanks in advance!
