My musical tastes cover the entire spectrum
I have never owned Marten's, so filter my comments as you wish, but I have heard them at audio shows several times. I like their speed and their articulate sound, but I do note that they tend to offer no warmth, in and of themselves. I run some TAD CR-1's that also lean in that same direction, and I have been very pleased with Elrod Gold Statement speaker cables with them. I get the articulateness inherent in the speaker, and I get a fuller harmonic presentation, more "meat on the bones", as it were. I strongly suspect that they would work similarly well with Marten speakers.
Douglas Connection Alpha 12AWG OCC Speaker Cables might work nicely. I very recently heard the Django(not with the Douglas cables), and I would agree with jbrrp1 above about their sound, which seemed to me to be just a bit "sterile" or "analytical" as some people describe certain speakers. They also did not seem to have much bass extension and impact.
The Douglas cables offer great imaging and soundstage, but with awesome bass impact and slam, and being made with "Finest OCC (Ohno Continuous Cast) long grain Copper Speaker cable available from Furutech", offer a touch of "warmth".
I recently heard the Douglas Alpha 12AWG OCC with a high end tube amp system and big Legacy Audio speakers, and the sound was awesome.
