air, detail, soundstage, tonal accuracy, etc.? Rich is what I'm looking for, without draping a false harmonic blanket over everything, and, of course, as glare free as digitally possible...
After having several interconnects in my system over the years from the likes DHLabs, Zu, Cardas, Voodoo, Stereovox (now Black Cat), I've always come back to my Acoustic Zen Silver Reference. While some other interconnects showcase more upper-octave detail or more syrupy-rich tonality, the Silver Refs manage to combine just the right amount of tonal color without sacrificing treble detail or air. Combine that with excellent 3D soundstaging and the result is a very engaging and natural musical presentation with no particular area calling attention to itself -- at least to my ears and in my system. If this is what you're looking for there's a pair available here now in your price range (no affiliation) that you could probably sell at little or no loss if they don't work for you as there's a pretty fluid market for AZ cables. Hope this helps, and best of luck in your search.
