Just a slightly tangent update to this thread. I found a seller here on Agon who goes by the handle "vox". He has a source of NOS Western Electric KS13385L-1 26 Strand 16awg on the reel that he used to make an 8-foot pair of speaker cables with smaller spades on one end for my Altec Valencia 846A speakers and bananas on the other end to plug into my Shindo Lafon monoblocs. I've been running them since March 2018 in place of my Auditorium 23 speaker cables with very good results. You might want to check him out. Very reasonably priced. Down the road, I may buy some Dueland cable manufacturered like the NOS WE cable just to A/B them for grins.
