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.

i read this thread with deep interest.  First of all the size of the room does matter with the Merlin VSM get past 16X16 and they get swallowed up.
First thing that has to be done is the BAM must be inserted into the musical stream BEFORE the preamp NOT after.  THE DIFFERENCE IS MASSIVE IN THE BASS DEPT.
2nd thing is go to Lowes and get a pair 12"X12" 1/4" thick steel plate and accurately drill 4 holes to mount directly to the speakers and then 4 holes for the spiked feet into the plate.  Massive difference
Then get yourself some amplification that can do the job 
My favorite is the Quicksilver 6C33C 50 watt TRIODES (hard to find) but second is the ARS SONUM Filharmonia 30 WATT PER CHANNEL
I also love the DH LABS Deity speaker Cable yes expensive but worth every penny and DH Labs Revelation for all your IC's Expensive but worth it.
Get some Charcroft resistors and some Duelund for the back of the speakers RC network
And finally purchase a HATTOR AUDIO active and passive (combo) about 4K but  the best you can buy Arek's top of the line separates preamp as he is making the best attenuators out in the audio kingdom and if your so motivated replace his capacitors with Duelund
All of this combined will make the best sound in the universe.
BUT REMEMBER THERE IS NO CHEAP WAY OUT WITH MERLIN ...QUALITY IN QUALITY OUT PERIOD.  IF YOUR THINKING I'LL SKIMP SOMEWHERE YOUR FOOLING YOURSELF.  As a gentleman said on Audio Review...."what do you get when a genius workds all his life on ONLY 2 speaker models...you get PERFECTION. "
I'm toying with a purchase of pair  Joseph Audio Perspectives to replace my Merlin Black Magics.
I've heard the speaker at 3 or 4 audio shows and have a friend who has a pair in a moderate sized room 22x15 and is getting great sound. He's driving them with 100 watt EL 34 VTL mono blocks tube amps with great success.
Nice sounding speakers. 
Jimbo... your custom room is ~13' x 18' and you're thinking you need a bigger speaker for it?  Are you sure it isn't pollen causing an itch?  In the past, I've lent a friend my Joule VZN-80 amp for a while... he still talks about it.  Could be that you need to trade speakers with your friend for a while and you both ride a different horse.  If you decide to get rid of those old, tired, Merlin Black Magic speakers, be sure to let me know so I can send you my address...
