For that combination of electronics and loudspeaker I would recommend that you try Wireworld Gold Eclipse 6 or Platinum 6.
I think you will find their lack of smear, transparency, weight and dynamic impact to be very well suited with Martin Logans electrostatic loudspeakers.
Despite that they are silver cables I find these interconnects to have the most natural dynamic impact so far. Overall excellent interconnects.
For loudspeakercables ?
Mid/high I would say Magnan Signature, and for lows something from MIT's better range.
Like MH-770 CVT Twin.
That combination will perform excellently without making a hole in your wallet.
I have tried a lot of different Cardas cables too, but to me they sound quite colored and lacking in both the extreme low and highs. Midrange and upper bass have some extra glare that some find appealing. Not me.
Both Wireworlds will outperform anything from Cardas with quite some margin IMHO.
