R, the basic economic options are $3K for new ZYX Airy3, so trade-in is $2100 (retail x 70%), $300 re-tip ZYX see how it plays, or discount on universe from $5K or so. It would seem worth the risk to spend $300 to see how the re-tip might sound recognizing the aforementioned inconsistencies that will be introduced. I think my system is up for the universe but maybe not the wallet right now. One other idea is to get the ZYX re-tipped and then get something else (Koetsu?) for the sake of variety.
