Upgrading path from Merlin VSM black magic


Goal:
I have been tinkering with the idea of upgrading and investing in floor standers that are superior in every way compared to Merlins. What are the Merlin users upgrading to? budget is 25k or under (used market value).
My present system:
I am using my Merlins VSM Black magic with dual BAMs with Coincident tech Frankenstein mono block amps (300B SET) and coincident tech line-state and phono preamp. Whole system is wired with Cardas clear cables. Using EMM XDS-1 and VPI classic turntable. System was built around Merlins. I suppose I might have to pick electronics suitable for the replacement speakers and in that case will build the whole system again. Preferably, I would like to keep the front end electronics/amps/pre-amp etc.
My music taste:
I listen mostly Jazz, Classical and vocals. 
My room:
I had Merlins setup in 12x16x8 room which was fully treated. I have since moved to a larger-ish space 15' x 21' x 9'. The room is not treated yet but would be fully treated with absorption panels/diffusors etc in the near future. I setup speakers with ears and with RoomEq software. 
Why not Merlins .. ??
I have thoroughly enjoyed Merlins but sometime feel it can sound a little thin and won't reach the lowest bass. Larger sound stage is desired. Full scale classical music can have better depth, width and weight. I have been using various versions of Merlins since 2009 and have the last version produced (Black magic) with dual BAMs. I have purchased two Funk Audio subwoofers that I have not integrated with the system yet. Merlin is not very subwoofer friendly anyways.
What I am looking for:
Ideal speakers would get from "Merlin" its neutral, resolving, transparent, low distortion, dynamic character. On top would also deliver fuller sound (top to bottom), be a full range down to 20Hz, provide bigger sound stage and has a more organic / relaxing sound (..better emotional connectivity). Speakers should be tube friendly, (preferably SET or OTL).
Brands:
There are simply too many out there. These brands come to mind: dynaudio, magico, sonus-faber, mbl, B&W, wilson audio, rockport, jm-labs, dunlavy, wilson benesch.  I am sure someone who has owned Merlins and made a move can give their input. Even a short list to audition would be helpful. I am based out of Orlando area. Would be great If any local member has a system that they can allow me to audition.
Past experience:
Other notable speakers I have owned in past include original Flocal Utopias (mezzo to grand Utopia), B&W nautilus series, Quad 989 among others. Yesterday's nautilus 800, 802 were power hungry and sounded boxy. This may not be the case with the newer models.  I feel like I am out of touch with what is out there. Have been out of market for long. 
Thanks.

Rich, great that you continue to support the Merlin community. As good as the VSM series was/is, I wish that Bobby had carried the model forward with a serious update with slam for larger rooms. One idea would be to add a couple more 6.5" drivers to make a line array. Pretty much the same simple two-way second-order crossover, BBAM, and slim cabinet profile, but with increased output and headroom. Nice if you could explore it...
Dave, you are not the only person who wanted Bobby to make a bigger VSM. Your idea is not a bad one, alas I am not a speaker designer/builder... and the speaker manufacturing business is a very difficult and competitive one (not inexpensive to do either). Right now as well, I have my hands full with running my little retail business end of things, handling Joule-Electra support/repairs/upgrades, Merlin VSM/TSM/BAM support/repairs/upgrades, and also working on getting Ars Sonum integrated amps re-introduced to the American market. All this is taking up much time (and money - spare Esotar tweeters, VSM/TSM woofers, test equipment etc etc).

Something more in my bailiwick (with my EE background) is the BAM - and I have been looking into (its a long term project) some improvements for the BAM that would not be too costly and still work with the current BAMs enclosure, board, etc and make some good sonic improvements.

Cheers,
Rich
When I imagine a larger sounding version of the VSM speakers I think of the EgglestonWorks Andra. I own the Fontaines which, to me, sound similar to the VSM (without the BAT), and seem to have similar physical makeup. I thought the Fontaines sounded a little richer in comparison. The Andras even more so with terrific bass.  
@dgarretson and @signaturesound : thank you guys for valuable input on BAM. I will try to upgrade the BAM if I stick with VSMs. 
So here are the options mentioned so far in this thread. These are not necessarily suitable with SET or low power amp but that is a discussion for another day. So the list :
Von Scheikert
Coincident Tech line
Dynaudio
Audio Note AN/E
Charney Audio Concerto
EgglestonWorks Andra
I would also add Devore speakers and possibly the new Paradigm Persona speaker line. This is a newer line so not sure if it's compatible with medium powered tube amps but the specs are promising.
