I use AudioQuest King Cobra (XLRs) as my interconnects from the DAC to my Krell Integrated Amp. I bi-wire my MartinLogans with double runs of AudioQuest Gibraltar (each pair only 6 ft. long). Although I had not intended to bi-wire with Gibraltar, when I replace my previous AudioQuest bi-wires with a single run of the Gibraltars the result so startled me, I immediately sat down and ordered a second pair.
