I've been using Satori shotgun biwires for a while as well, and though I've had several others in here I keep coming back to the AZs for their balance of strengths. They're detailed enough to keep me interested and let me know what's going on in a recording, but they're not overly so and they allow tonal colors to come through and sound organic and natural in the process. Not to say they're near the best in any of these categories, but I think it's their balance and natural presentation that keeps me coming back to them. I mention this because you seem to like them for some of the same reasons, so maybe re-terminating them might be a good option if it's cost-effective. Then again this would seem to be an oportune time to try different cables, but in your price range I can't think of anything off the top of my head to recommend. Morrow might be worth a try since someone above preferred them to the Holograms and there's a nice trial period.
I'm a little confused by your interconnects. The Matrix Ref. IIs were not the originals. I find the original version to be quite a bit warmer, fuller, with less detail up top than the Matrix Ref. IIs. I have found using the Silver Ref. IIs from source to pre and original Matrix Refs from pre to amp to be a nice pairing. It preserves most of the warmth and tonal richness of the Matrix Refs while adding a nice bump in transparency, air, bass tightness/speed, transient snap, image focus, and soundstaging without going too far (at least for my tastes). If that sounds like characteristics that might benefit your system/tastes you might consider giving it a try.
Hope this helps, and best of luck.
