Where to hear ATC speakers

Thanks for all the advice, and thanks to the dealers who reached out.  Just to respond to some of the comments above:
1) I looked at the dealer locator, but the public websites of the two dealers in the area didn't suggest anything about ATC, let alone availability of demos of the models I might be interested in.

2) I have been speaking with Coherent.  They seem to want me to self-serve repairs, which I'm ill-equipped to do.  I believe it is the crossover that is fried.
3) MusicDirect does not extend their return policy to ATC special orders.  I spoke with them.  Neither does Sweetwater.

4) The only ones I've auditioned were the Wilsons.  Very impressive image and liveliness, awesome vocal timbre, but I got the impression they might be a little fatiguing over a lot of listening.  It's almost as if the Wilsons push the image towards you, whereas my Thiels tended to create a solid image at speaker position and behind - more of an audience position.

I listen most critically to classical chamber music (my wife plays viola and I get a lot of live comparison time) and jazz (I went to Berklee and gigged a bit in my youth, before turning to finance), some orchestral and rock.  I'm listening to music, passively or in a focused way, almost all the time I'm home and awake.  I like to hear the instruments laid out in front of me, as if on stage or a small venue, each in their spot, not popping out and retreating (some mixes are deadly this way).  But I'm also cognizant of the fact that one tends to grow accustomed to a certain sound, even inaccurate.
I have a pair of the little active KEFs, and they create a really nice image. Small-scale, though.  In general, active speakers make a ton of sense, side-stepping, as they do, the first order crossover complications.

I have a server with about 1200 titles, roughly 250 High-res of one sort or another and the rest redbook.  And Tidal.

I'm not very technical, but here's ATC's claim:

" Active filters allow independent control of level and phase(time). This is not possible with passive crossovers. With a passive crossover any changes you make to the circuit affect both level and phase. The benefit this allows is that we can adjust for the crossover to have a perfect magnitude response and phase response. The result is that the stereo imaging is much more stable and the tonal balance of instruments is improved. " 

At any rate, as I said, I've heard the active and passive versions of the same KEF, and it's night and day.  And generally, I think the amp-load matching opportunities in active designs eliminate/optimize much of what people hear as differences in expensive amplifiers, right down to the driver level. I remember that Julian Hirsch's infamous blind A/B/X amplifier listening test involved a mediating gain/impedance-matching step that probably fouled the experiment, but I could be wrong. (ducking away from object thrown by amplifier mavens).  I also run balanced, and like the idea of going balanced to the speakers.

I'm in touch with a NYC shop called anologique that seems to have been around for a while.  A few nightmare reviews on Yelp, but some good ones too.  Open to suggestions.  I'm getting an estimate to move my speakers down there next week #NYCapartmentliving.

I listened to the Wilson Sabrinas this weekend with the higher end Naim Uniti integrated (courtesy of Innovative Audio in NYC).  This time I spent a very happy and involved hour going through my demo tracks and then a bunch of stuff on Tidal. It was much easier to imagine having them at home.

Still haven't tried the Vandersteens.

I really don't know what to do with the Thiels. Presumably the parts have value.

  (I posted this same comment in an older, Paradigm-related thread)

I want to thank Dave from Audio Doctor ("Audiotroy") for letting me listen to KEFs (3R) and Paradigms (Persona 3f) last night, mostly with the Naim Uniti Nova DAC/amp. There aren't many places where you can try a lot of great brands (including schlepping heavy speakers around) in a relaxed environment, and he offers that. If I buy something he carries, I'll try to route the order through him. I think we have to support places that let you listen.

I found the resolution and soundstage of the Paradigms to be extraordinary. You can hear the wood of the solo viola, and the movement of cymbals when struck, the voices and locations of individual string instruments (even low strings) in ensemble, clear as a bell. I don't think it's a speaker for big bass, but that's not a huge priority for me. I like the impression of the ensemble or orchestra laid out in front of me, life-size as possible.

My only reservations were a) I don't find them terribly attractive visually, and more importantly, b)possible longer-term listening fatigue. The Paradigms came off as a little hot in the treble, to me. Dave disagrees, in person and in this thread above.
Doubting my aging ears, I looked up test bench measurements last night. Multiple measured (on-axis) frequency responses of both the 3F (and 5F) are certainly consistent with what I heard, showing a substantial bump from 5-12khz:

They were toed in a bit, and if you look around you'll read a bunch of reviewers/users are setting them up facing straight ahead to avoid an overly bright presentation.   I'd like to listen to them against the KEF Ref 1 (and maybe 3), and try the off-axis set-up this time. Apart from the brightness, I think the Paradigms are *very* stiff competition for the much more expensive Wilson Sabrina.

The KEF 3Rs are a really nice speaker. Not quite up to the resolution and soundstage size of the Paradigms, but a great value for much less, and great looking (in Walnut particularly). I think you could spend a lot of happy listening hours with them, and I suspect it would be hard to do better at that price point, at least from my limited experience.

I still wouldn't mind listening to PSB T3, Monitor Audio, Vandersteen. The latter is a longer drive, and the former two would seem to require mail order trial, which is a schlep with such heavy units.
One possible wild card:

I have a pair of JBL L830s in my country place. My son bought them for me after blowing out their predecessors (Mirage). I am often very pleasantly surprised with these little $400 speakers. There is no good listening position in this (angular,open-plan, 1968, architect-designed) house, but the horn covers a huge part of the frequency range smoothly and sweetly (never really been a horn guy before), they throw a decent image from a variety of listening spots, and they have surprising bass response (I ended up getting rid of the subwoofer). It makes me wonder what the $10k S3900s can do with a similar design. JBL is pretty mass market now, but I have some fond youth memories of them....
