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.

Look at the Dynaudio C2's or C4's.  They will give you everything your Merlins give you plus what you are looking for that the Merlins do not.  Plus, at least IMO they are gorgeous.  

I almost went that route myself (I have the Black Magic edition) but couldn't quite persuade myself to pull the +/- $15k - $20k trigger.  Based on your new room size the C2"s may do nicely (not sure about full scale orchestral) and can save you a tidy little sum over the C4's.

Good luck.
Tubegroover: I bought two Funk audio 18.0 master/slave subwoofers that I have not integrated yet. Overall cumbersome with BAM in the chain. It would be interesting to see if this ends the quest.
To audition list: 
Von Scheikert
Coincident Tech line
Dynaudio (btw, what amp is preferred?)
..(to be contd..)
If you integrate the Funk audio 18.0 master/slave sub-woofers into your system you can do away with the BAM as the subs will take over the frequency band in which the BAM attenuates.  Have you looked at the Coincident line of speakers?
I agree with you brf. You can just lose that BAM with a properly integrated sub system, at least I would give it a try. I know this move would have been considered sacrilegious to Bobby. The whole idea to me IS the BAM being cumbersome, adding more in the signal path. It would seem subs might negate that need and give you a fuller more full range presentation without the need to trade "up". You have a fine pair of speakers with the Merlins. Yes they always had their weaknesses but it was due to a 6.5" driver not being sufficient for full range sound regardless of all the tweaking Bobby did to try to overcome that simple fact. They are simply lean in the mid/lower bass and produce little to no info at the lowest frequencies. Believe me for years I tried and was always told I needed to replace this component or update the speakers to get a "fuller more fleshed" out presentation. I came to the simple conclusion you can’t make a silk purse out of a sows ear. Those speakers require a subwoofer that integrates seamlessly.


Good luck sstalwar.
