Thanks @mofimadness . The length is only 1.5m but I enjoyed what seemed to be a blacker background and higher S/N. I should mention I did a shootout between Audio Envy and Zavfino balanced. The Audio Envy was too warm and their Pro series (a custom order) was excellent but brought the soundstage too far forward, like I was sitting in row one of the concert hall. Zavfino OCC copper and silver was good but after hours of break-in, the highs dominated at the expense of the midrange. I was missing the sweet mids of the woodwinds and French horns, and I'm using all Amperex in my dac and pre.
