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’m going to keep mine to what I’m likely going to upgrade to and not go into dreamland as I have a wife. My current speakers are Aerial Acoustics 7B’s and I lust to hear a pair of 7T’s. Probably have to buy them from that dealer who loves them but loves to mention they unfortunately make the cabinets in China. 
Michael Kelly should do what JBL did with the L100 and bring back a special, revamped version of the 10T but keep the cabinet appearance the same. Also maybe make them a little easier to drive would be nice too.
I wasn't bashing magico or the A5. When I read stereophile writers i try to read between the lines as their listening impressions more and more stray from what measurements suggest they should be hearing. I'm NOT an asr guy, and usually trust my own ears first, but the more measurements deviate from listening impressions the more I remind myself these reviewers are writers by trade. My reservation with the magico a5 is how early the treble rolls off and my aging ears might not make a great combo. I just bought the Kef Blades so probably game over for me.
I see what you mean. In the JA measurements they roll off after 5khz.

I'd love to hear your blades. Cingratulations.
I just looked at the MUON price, $224,999. Wow.
Yes, oh yes. Borresen 05s would be a thrill to hear.  I'd also like to listen to top of the line Tidal and Rockport loudpeakers.

I have listened to many loudspeakers, including your KEF. The A5 are incredible loudspeakers and, at their price point, the best I have auditioned. You are not interpreting the measurements correctly, try reading JA comments.
