Given your preferences and amp I’d give a very high recommendation to the Verity Audio Otello.  Verity flies under the radar a bit, but they remain some of the best all-around speakers I’ve ever heard as they’re supremely natural and lifelike sounding and can image/soundstage with the best out there, and they’re very tube friendly.  Here’s a nice used pair you can get at a steep discount and save $$$…

Here are a couple reviews that I think capture their sound characteristics nicely…

These Ushers are also excellent but I’d check if they’re compatible with your amp just to make sure.  Oh yeah, and they’re drop dead gorgeous.

If still available, these Acoustic Zen Crescedos are also excellent and like the others could save you some big $$$.

Another top contender that will do what you’re looking for in spades, looks great, and is very room friendly due to its size is the Joseph Audio Perspective 2.  I also like your QLN and DeVore choices although I’d check that the QLNs are suitable for your amp.  

Anyway, just some other choices to consider, and best of luck.

Thank you all for some great recommendations! I don’t post much, just stalk the boards. Appreciate everyone’s time and thoughtful responses!

thanks for using it @elliottbnewcombjr !

if you have any suggestions on how to make the search better, what other data you would like to see, please let me know

I don't think the DeVores come near the other recommendations in value. They may be great but they are overpriced - based on a few attributes.
