I've got a related, though somewhat offbeat question. I'm contemplating replacing my "Home Depot" biwiring to my Summits with a cable from IXOS called the Gamma 7. It's a low inductance design which has two sets of conductors, a 13 ga pair and a 15 ga pair. In most applications the 13 ga would be used for the LF and the 15 ga for the HF. Here is the question.... since the Summits LF is self powered, and the LF speaker cables job becomes more like an interconnect than a power handling speaker cable, should I reverse the normal application and use the lighter gage for the LF and the heavier for the HF?
