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.

I'd like to hear any of the Tidal models. The finishes are about the nicest I've ever seen.
Over the years there have been dozens of speakers I have seen in Asia, Europe, Australia, Hong Kong etc, that I would love to hear. But I’m not spending my own money to do so. No point in it if they're not imported and generally available.  
Kef 201/2 although I give up on ever finding a set of pre-owned ones. They must be great because those who have them never seem to put them up for sale

Kef Reference 1

Canton Reference 9k

Kennyc -
I heard the Pure Audio Project speakers with the Voxativ AC-XP field coil driver at the NY Audio Show a few years back and was mightily impressed. Subsequent auditions of other Pure Audio Project speakers without the field coil drivers were not as satisfying, although granted those were at different shows with different ancillary equipment. Based on my admittedly limited listening experience I would heartily agree with your assumption that those are sonically significantly superior, albeit at an also significant price increase.
…..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.
