Floor-Standards to Monitors?

I am always tempted to try a good pair of monitors/bookshelf speakers mated with my two subs and see if I can equal or surpass a good pair of floor standing speakers ($15k to $30k) in my 20 x 16 (vaulted ceiling) treated room. The thought of being able to move and set up things without help is very appealing as I get older.  Also, with much of the price of floor standing speakers going into the large cabinet, I am thinking that that an equivalent, or better sound, less the low end should be achievable at “reasonable” prices.  With the application of DSP/room correction, does this eliminate the gap between most of these products? Once you get to a magic price point, are we just paying for company name, exotic materials that may or may not have an impact, and aesthetics?

There are so many monitors out there and the price range is staggering – I have named a few below. The magazines say they are all wonderful and clearly there is no place to hear them all. Where there are measurements, it differentiates them somewhat. I like dynamic resolving speakers (Magico/Vivid) and concerned about mid/bass impact between 80 Hz and 250 Hz when you crank them up where the subs do not help. I would also like a US presence and a company that builds more than 25 copies a year. What do you think? Can I get there? Is paying more than $5k just crazy for monitors? Does room correction level the playing field? Any thoughts or recommendations?

ELAC DEBUT 2.0 B6.2 and AS-61 – both sounded very good at AXPONA

ATC – Never heard them / multiple options

Kii – Great reviews out there but all seem to point to a small room

Revel –M126 Be

TAD – ME1 – sounded great in small room at AXPONA. Likely too small for my room and very expensive as you move up the line

Dynaudio – New Confidence 20 monitor coming out and Contour 20

Focal - Diablo Utopia Colour Evo (expensive) and Sopra 1

Dutch and Dutch – Not highly available in the US but supposed to be exceptional

B & W – 805 D3 – Would need a very treated room

Paradigm – Persona – I have found the entire line bright and lean on bass

Fritz - Carrera 7 Be- A small company but sounded excellent at AXPONA

KEF – A laid back.

Raidho – Expensive

Magico – Very Expensive and old Q design

Harbeth –Cabinet resonance built in - odd
