JA in the measurement section you repeated your time domain measurement with the microphone in JCA listening position
You commented that one midrange was still misaligned probably by one step
Can we conclude JCA listened with this misalignment for the listening tests ?

Wilson used a modified Focal Titanium dome almost exclusively, so as far as the exclusively "soft dome" claim goes..

I love how you used Selected Ambient Works to audition the loudspeakers. "To Cure a Weakling Child" is also really great for analyzing a system -- the "soundstage" is like the aural equivalent of a cubist painting.

...is another great AFX option for testing systems, what with the panning, full-frequency wave-surfing, and holographic bouncing ball!

Stereophile should have an electronic music column, in addition to Classical/Jazz/Rock.

I recently heard 3 songs I'm familiar with played on these through Boulder electronics and, while it was clearly a good system, they just didn't move me. Wilsons never have (I am not a Wilson hater). By contrast, I recently heard a pair of Rockport Cygnus driven by Gryphon electronics and was truly mesmerized. That system revealed to me what those who can afford the best are after in their pursuit. The music was just there - organic and beautiful. You forgot to think about the system reproducing it. Not so with the Wilson/Boulder combo...not even close.

As almost nobody says, "One size does not fit all."

Good for you for recognizing and acknowledging your own tastes! (That was meant as a compliment.)

I'm fortunate that a dealer near me carries both Rockport and Wilson loudspeakers, so I've heard a number of models with different amplification, including Gryphon. I suspect the Alexx 5 with Gryphon would prove a good combination. I have most enjoyed hearing the smallest Rockports and Wilsons (Atria II and SabrinaX). They strike me being much more accessible in both price and in working well in more modestly sized rooms. They really don't give up much to the larger models except in ultimate dynamic ability and bass slam. Or, maybe I'm just too old now....

I haven't heard the Rockports you mention -- or these latest Wilsons either. Maybe they've made progress. But a number of years ago, at a dealer, I listened to a pair of their mid-sized floorstanders as well as a huge model like the one reviewed here. Both struck me as dull and uninviting, lacking the kind of freshness and presence I like to hear.

Heard Wilson Alexia at the local dealer and was unimpressed. Walked out after 10 minutes. Not for me. Maybe they're good for Mahler and not for smaller scale music? Just sounded thick and heavy to me.

It's great that we have choices. As I said, one size does not fit all.

(Full disclosure - we own neither Rockport nor Wilson loudspeakers here...)

From the experiences I've had, I would say that your audition experience had far more to do with the Boulder amps than with the Wilson speakers.

As good as they are, Boulder amps just have never moved me the way I have always thought an amplifier of their caliber would, where Gryphons to name one certainly have. That's even true for the Boulder 3050/3060.

Boulder would tell you that's because Boulder is technologically accurate, where other brands tweak their amps to sound good or more "musical."

Thus the old dilemma of high-end audio: do you want ultimate accuracy, or do you want your system to make your music enjoyable?

They're not always the same thing.

My wife's interior design lady was working on our window treatment, I asked her how she would place these Wilsons in our living area. She shyly suggested some other design, I agree.

These things are Visually-fear inducing , A dark room might be the owners better adaptation.

We saw this design portrayed when Mr.JVS had an introduction to the $750,000 version in the Utah home of Mr.D.Wilosn, the photos made the Loudspeakers look rather sinister as it stared down at our humble friend who was sitting in what looked like a Funeral Home.

Of course, this type of industrial design probably belongs in the Man-Cave Basement where banishment is the normal life experience of our typical obsessive Audiophile.

In response to Focal Tweeters: It was said in Stereophile ( somewhere ) that Focal stopped sharing their outstanding
driver manufacturing with other loudspeaker Manufacturers. Who makes the Wilson Drivers ? , I hoped that our intrepid Mr.JA2 would've inquired and reported. ( guess not )

There was a time when I sold Wilson Products. ( a few decades ago ) I still feel that Wilsons are Status / Ego type products. ( well made )

ps. no loudspeaker can duplicate Live ! but Klipschorns can duplicate a amplified Performance

With that 92db efficiency and hellish load you only need an amp with 25w or more, but it has to take that load, and almost double all the way down to 1ohm.
I can think of the perfect amp, the classic Mark Levinson ML2 monoblocks, which are only 25w pure Class-A into 8ohm, but then 50w into 4ohms, 100w into 2ohms and 200w into 1ohm.

Cheers George

... should come bundled with one of Dan D'Agostino's amplifiers to ensure that the amp can drive the 1-2Ω impedance that these speakers present.
Either that, or a Rotel RB-1582 which, according to a test in Hi-Fi News, has a peak output of nearly 300W into 8Ω, over 550W into 4Ω, 1kW into 2Ω and 1.6kW into 1Ω.

Some more recent Wilson speakers have measured very well. I see this overpriced piece of garbage is a return to their former engineering prowess, with a speaker that costs nearly as much as a house, and surely as much as a luxury car, that measures worse than a $500 Wharfedale, KEF, or Polk, and certainly not as well as similar stratospheric priced offerings from Magico, Vivid, Revel, KEF, Focal, and others. Apparently they've learned nothing over the years, and the recent Wilson offerings that measured well were merely flukes

Given your expertise, I look forward to your analysis of how this loudspeaker has so badly failed acceptable engineering standards...

Those big beast monoblocks were the best solid state amplifiers I ever heard.

IF I ever had to give up tubes I would definitely be looking for a pure class A power amp.

Those ML's were really something

Not a Wilson denier (Hell never heard one) but as I am not a cone and dome guy at all. For those with the coin and space more power to them.

Like, it's so cool: goes up to 11 !

Have you heard the new Diptyque Audio Reference Loudspeakers yet ?

I listened to the Alexx V at a local dealer with top of the line Audio Research and Transparent cable. They were playing some weird jazz fusion recording when I walked in. I was able to play (streaming from Tidal or Qobuz) my go-to track, "Easy Money" by Rickie Lee Jones. Considering that the cost of the upgrade paint job alone (cranberry something; gorgeous) cost more than my 15 year old Revel Ultima Studios, I was expecting something extraordinary! I didn't get it. When I got home, I listened to the same track on Qobuz, and my system, with much more humble electronics (PS Audio, Bryston) sounded better (to me) in every respect where the Alexx V failed.
