Are 'Chord' and 'Chord Cable' separate businesses? I have tried some Chord cable (something called Tuned ARRY (?)), and found them to be the only RCA phono terminated cables where I could hear a definite, but subtle, difference that was repeatable and distinct.

Like Gary, my system largely uses balanced-line connections. Some of these use cable marked "WWW.CHORD CABLE.COM". Can't say I've noticed any difference between those and other cables using either Klotz, Mogami, EMT, Neumann or Gotham.
