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'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... 
Checked out those Joseph speakers... Imagine a VSM with that setup.

I get it. 
"what do you get when a genius works all his life on ONLY 2 speaker models...you get PERFECTION. "

What a nice tribute to Bobby.
jim2,

 Yea, JA Perspectives would load into my room Perfectly. They are actually smaller cabinet than VSM. Not worried about the size... Just a different flavor than the Merlin.

I Took 2 asprins to see if this helps the fever! :-)  We shall see.
i have the same speakers 
but with one Bam   Do i need to get one more
 for upgrade in sound 
 like Mono block Bams   yes?   is it really worth it  or a  $ 2300  - $ 3 k  DAC   better investment  thank you

@twoch In regards to mono block BAMs (for RCA based systems - i.e not balanced gear), not a worthwhile upgrade as the design of the BAM is dual mono after the raw batteries/external DC supply (any gain there is likely small given the cost).  Now if you have a (again RCA in/out) Super BAM (more so one that is not up to date), upgrading it to a Master BAM WILL make a worthwhile improvement in sound.

Dual mono BAMs are only a necessity if you want/need fully balanced (XLR in/ou) Master BAMs as all the required boards/parts needed physically will not fit in one BAM enclosure. 
I think you need more powerful  electronics, e.g., Art Audio Jota HC uses 300BXLS tubes and yields 24 WPC SET sound. 
That speaker has efficiency rated in the upper 80s- you do need some power. In practice it seems to be conservatively rated, but there is a reason why Bobby ran more powerful amps - 60 watts or more.
Happily ran Merlin Black Magic monitors for years with JL subwoofer and lots of Manley gear with proper cabling, Quadraspire stands and massed speaker stands.  Everything I could do and finally went active for the dynamics I sought.  I'm there now.

There are lots of salient pieces here on ATC active speakers and nobody has gone back after the conversion.  Best of luck finding your sound.
