Cables advice for ARC + Mark Levinson + Wilson

Hi all,
My system:
Pre: ARC Ref. 3
Power: ML 33H
Speakers: Wilson W/P 7

I am tuning the system with new interconnect cables.
I have used MIT Magnum MA XLR between the Pre and the Power amplifier but the result was a lean sound without dynamics and without bass. I would say that the cable has produced a too dry sound.

So I tryed Transparent ULTRA RCA that I got in house and I got much better bass and dynamics.

So, considering that I will discard the MITs, what the best cable for this setup on the surce-pre and pre-amp interconnection?

I'm considering:
- Transparent Reference
- XLO Signature
- others...
