What I can say is that I switched out my FMS Black speaker cable for Morrow SP6 and my Kimber PBJ and Mogami interconnects for Morrow MA4s and three seasoned audiophiles heard a significant positive difference. We also did comparisons between older mid-range MIT interconnects, Morrows MA5s, and PBJ. The Morrow interconnects were on par with MIT and both were better than the PBJ.
I did also talk to research scientist who has oversight on building satellites for the DoD and while I can't begin to recount his explanation, he did infer that there is research that dates back about 2 decades ago that supports the Morrow design philosophy.
Are there better cables? Sure, but I'm satisfied with the improvements I heard when I switched to Morrow.
