This may not be of much help, but who knows. I'm using the Acoustic Zen bi-wired on the new 803d's. Amp is the Cal Audio MCA 500. Switched from the Audioquest Gibralters which I had on an older system with 805n's. My room is very bright and the Gib's just didn't cut it. Way to lean with the 803d. The Zens really smoothed things out without losing detail. Soundstage is fantastic and base is nice and tight. On top of that, they are much cheaper than the Gib's and many others. I demo'd a ton of much more expensive cables and was most happy with these. There may be better, but this combo sounds great in my room with my gear.
