Interesting. It sounds like our sense of speakers overlaps. I owned (and liked) a pair of L1090/2s for almost a decade (plus a few years with some L810s). I replaced the L1090s with Mirage M5si's in 1996, which I still have and use. I have since added an analog-sourced 2-channel system, and the speakers are Magneplanar 1.7s augmented by a pair of Mirage MM8 subwoofers.

The ADS-L1290/2 was always the speaker to replace my Magnepan-SMGa but being a young adult I was never in the financial position to upgrade. It wasn't until I heard the Mirage M5si that an affordable speaker was competitive with the ADS.
If you like consistent in-room power response (and dispersion), transparency, midrange honesty, detail within a broader musical context, you will--like the OP--probably like a/d/s/, Mirage and the other Canadians, and possibly Magnepan.
To the OP, no it's not just you. ADS was ahead of the curve in power response, tonal balance, transparency, etc. It was a sad time for me when ADS dropped their high end aspirations for their "lifestyle" models and died off soon after.
