@blisshifi , that's a good point, I might try the original phono cables again, see what I hear. The Dimension cables I bought weren't brand new, they were sold to me at a discount by DH Labs as demos, they'd been used at a show. Still probably didn't have more than a dozen hours on them.
@audphile1, you might look at usedcable.com. Hard to say what might pop up. Or ask DH Labs if they ever have other used demo stuff.
