I'd put the Acoustic Zen Satori on your list. Detailed but natural-sounding highs with expressive and full mids. Bass is also full but not the tightest I've heard (not bad though), but that will likely be somewhat system dependent. Haven't heard the others mentioned (except the DH Labs and I agree with your assessment).
If I were you I'd try to upgrade the interconnects and speaker cables at the same time to try to optimize the synergy effect, but I realize that's not always possible from a budget perspective. Best of luck.
