Would help to know what aspects of sound are important to you and what you'd like to improve upon. Without knowing any of that, there's a pair of Acoustic Zen Hologram IIs (6ft, if that works for you) currently available in single or biwire at a little over your price range. I'd guess they're just a tad more detailed than the AP cables if that means anything. Anyway, they'd likely be a considerable step up from your homebrews, and if you don't like'em just turn around and sell'em. Best of luck.
