Have you moved away from full range to standmount speakers + subs?

I always had, and I still have full range speakers around.A smaller pair (mini tower) is the main speakers in my second system. It's about 91dB efficient, and does a fine job down to the 30s - wonderful for all genres, and bass quality and extension is much better than multi-way bookshelves. No need for sub for the material and volume I listen to with them. I have a Nakamichi tape deck and a turntable with that system, (no digital there), amplified by a flea power Darling Loftin-White amplifier (sporting 600+VDC power supply) and use it for quiet listening. It is just absolutely wonderful for quiet volumes: the emotional connection, atmosphere is very very deep.
(Regular bookshelves fizzle out at low volumes.)

For main system (main audio and movies) I moved to 10 cuft size ultra efficient cabinets.... they seemed humongous when I built them, but now they seem to have positively shrunk as I got used to seeing the size. In hindsight I think I could have made them 15cuft each... LOL. Curiously though these giant speakers have exceedingly high WAF. Who would have thought. Also, no need for subs, as they are practically monster size subs. Bass is transformatively different when you have the lung size to produce it.

I've had two floor standing speakers since 1978. 
 

I have not found a substitute for the idea that you need a commensurate amount of mass to move air. 

Glad to hear Millercarbon shares my choice as I have the Tekton DI monitors driven by a Peachtree Nova 300 and I recently added in an RSL Speedwoofer. It is audio nirvana for me and anything I play sounds detailed, deep and strong. The closest thing to live I've ever experienced. I'll likely add another RSL but that's it. I don't think I can improve on this system without doubling my budget and that would be a questionable ROI. 

If room size was not an issue and large enough, I'd have full size speakers (and probably still augmented with multiple subs). Generally speaking, a big speaker simply sounds bigger to me most of the time; there are well-designed exceptions.

But big speakers in a too small room sounds like a bad combo. My (gone) Dynaudio Sapphires could fill and play our 3500 cu. ft. living space set far apart however I now have Raidho D2s set in a nearfield 8' triangle and they are great. I don't think they'd fill the room, especially at volume, but I know they will work in smaller rooms if needed at some point. The joy in this little D2 floorstander is it cleanly digs to 30Hz and flat, in my room. So the subs are left turned off a lot.

I can easily see rooms where a standmount and subs may well be best but a well designed small tower will image every bit as well as a monitor in my experience. It would only be a small room dictating my move back to bookshelf speakers, and even though the Raidho D1s I had at home on audition were really amazing, the D2s are simply better; it's cabinet volume (and one more tiny mid-woofer).

 

 

I just replaced my 20 year old JMLab (Focal) Chorus 716s with the matching center channel with 3 Kef LS50 Metas sitting on Solidsteel stands and to me it's a massive upgrade. I replaced a cheap subwoofer with the Kef KC62 and it's like a veil over details and soundstage has been lifted. Aesthetically my ladyfriend is also happier with this setup so it's a win for everyone.
