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.
