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’ve been to many audio shows over the last few years. One stand out for me was the Nola reference line. In particular the Nola Metro Reference Gold. It was cheap, just the one I liked the best. Years past I listened to all kind of speakers, my ear came back to the Nolas. I had a chance to heat Nolas latest Metro Gold3. The opportunity was right I bought them. I couldn’t be happier. Im still amazed every night when they play. Cheap? No, he’ll I’ve worked 2-3 jobs my whole life. My present to my self. Earlier on the Thread someone brought up Living Voice speakers. I heard them years ago IBX-RW3 I was impressed. Someday I’ll pick up a pair of them. 
I would really like to demo the Sonus Faber Electa Amator III in my home. I´ve listened to the old Electa Amator II and they were one of the best bookshelves I had the pleasure to listen to. Humble desire :)
Avalon Tesseract- as the Eidelon models were one of the most realistic ones I’ve heard so far.

Infinity IRS
Altec Voice of the Theater’s
that I used for PA long before I was interested in home audio. In hindsight they never failed despite whether and modern 70’s electronics.
