What speaker do you passionately want to demo?


Beyond the slight curiosity of what speaker you'd "like" to demo (example: every Klipsch horn speaker), what speaker(s) would you "passionately" love to demo?  A brief explanation of "why" you like these speakers would be beneficial.

I'll start:

MBL 101 X-treme - almost a decade and reviewers still say it's amongst the best they'd ever heard.  Probably should be matched to the MBL Electronics

Living Voice Vox Olympian Horn - it's wood (maybe sounds more warm/organic), it's a horn, and it consistently gets good reviews at the Munich High End audio shows.

Muraudio SP1 - Electrostatic + cone hybrid speaker that received many rave reviews.  It's not an easy task successfully marrying the fast electrostatic to the slower cone to sound seamless.  This speaker was on my short list to purchase.

Voxativ AC-XP field coil driver - both Voxative and Pure Audio Project speaker offer the Voxativ AC-XP field coil driver as an optional upgrade, but it's an additional ~$7k (yow).  The reviews leads me to believe that this field core driver is sonically "significantly" superior above other choices.  

Mike Lavigne's Evolution Acoustics MM7 in his dedicated sound room.  The sonics of demoing speakers at storefronts or audio shows can be problematic depending on the audio chain and the room setup.  MikeL has a matured optimized setup that is sonically recognized as excellent by other serious audiophiles.

…..with the Voxativ AC-XP field coil driver …mightily impressed…are sonically significantly superior
Now you really have me curious for a listen

The A5 are incredible loudspeakers and, at their price point, the best I have auditioned. 
The $25k Magico A5 I consider a bargain - sonic performance surpasses Magico $30k S3 and competes with Magico $42k S5.  It’s my next purchase when funds allow hopefully within the next few months.

I heard the Magico A3, S3, S5, M3, M6 (at Magico’s showroom) so am buying the A5 without hearing first because I’m assuming it’s voiced similar- hope this is not a dumb idea. 

When I started speaker shopping, I tried to listen to the best I could find at stores and shows, then try to duplicate the sound as cheaply as possible while maintaining sonic quality.  Although many speakers like Wilson, Kef, Viva, etc sounded great, only Magico and YG consistently resonated with me emotionally.
Speaker design encompasses compromises- no speaker is perfect- it’s a facsimile of reality.  I’m of the opinion that most speaker bashing is due to a subjective preference rather than any gross deficiencies in the speaker design which would likely make them unsellable.  
Tannoys Kensington GRs. Have Autograph Minis in my bedroom with NAIM UNITI ATOM.  Smitten with Minis. Currently running Rockport Atria ii’s in my main system but am curious about the larger Tannoys. They would be a very different sound signature from the Atrias I realize.  
I would LOVE to audition:

Vandersteen SYSTEM9
Tekton 1812 Flagship, with 4 extra 4-10 Subs thrown it (for DBA)
I really want to hear ProAc K6's but I think there might be only one shop in the country that has them.

Next week I'm going to the local shop to hear Magico A5's and Rockport Atria II.  

And I should have a demo pair of Kudos 808's arriving before too long for an in-home audition.

I have a Naim 500-level system, currently with A3's.
