Need speaker cables match w/system?

I have MacCormack DNA-I with rev. "A" upgraded by Steve MacCormack, SNF line3 pre amp, SFD-2 MKII and SFT- I. I'm using the Kimber Bifocal xl speaker cables with JMLab 920. I would be appreciated if anyone might have known better match speaker cables for my system, thanks.
The XL cables are doing ok but I feel it seems kind of like a little dark it not really open forward, I don't know if it might be the XL speaker cables or my XLO Signature balance interconnects. I'm thinking of changing the XL to 5.1 XLO Signature speaker cables but I still doubt about it.
Hi Hanbt; What do you think of the DNA-1 Rev. A up-grade by Steve McCormack? (I'm considering having a DNA.5 up-graded). I use bi-wired runs of Synergistic Research Signature No. 2 with excellent results. It is mid-priced, detailed, neutral, and non-fatiguing. I auditioned mid-priced Cardas, and MIT before choosing the SR cables. I used these cables with McCormack's DNA-1 for 2 years, and now with the DNA-2DX-- they work great with both amps.
---Should have mentioned that I use a Sonic Frontiers Line 2 pre-amp, and Vand 3Asig. speakers.
