OP again, posting a followup. I looked into a lot of recs mentioned in this thread and soon realized that I wanted to focus first on speakers that I could immediately audition with my own amp. I also realized, for better or worse (and partly due to aesthetics) that I wanted smallish floorstanders. So I demoed several speakers at my local hifi shop and somewhat unexpectedly ended up getting something that did not get a lot of press - the now-discontinued Quad S5s. The bass, dynamics and sensitivity far surpassed my vintage Apogees while retaining the midrange magic of ribbon tweeters. And I got a great deal on them.
Obviously I will never know how the wide range of speakers given in this thread will measure up in my room and I’m sure some of them will outperform the Quads. But hey, I’m pleased with what I got (for now!)
If anything, this thread will provide plenty of great recs to anyone else in a similar situation. Cheers!
