I find Danny Richie's "antenna test" interesting in a sidebar context because I worked at San Jose's long-gone Garland Audio in, IIRC, 1978 when Bob Fulton walked in the door carrying--maybe "lugging" is more appropriate--a 28' pair of his new "Gold" 4-gauge speaker cable. The sight of it prompted John Garland to ask, "What are you doing with that towing cable, Bob?"
Fulton, as serious a guy as they come, was not amused. But Garland quit laughing after--with some hasty termination "improvisation" at both the speaker (Magneplanar Tympani 1D) and amp (a pair of ARC D-79s) screw-terminal ends--we managed to hook them up.
Fulton explained that he based his interconnect and speaker cable designs on antenna theory that posited 57" and its multiples as the ideal cable lengths to minimize noise.
(We sold a fair number of his IC's and 14' and 28' lengths of his Gold and smaller-diameter Brown speaker cables. But perhaps the most practical use of the Gold occurred when Garland moved to a new location and we had to take out a wall. Pulling it down with guess-what did the job in a hurry.)
