Think what you may, but I’m a regular consumer of Paul McGowan’s “Ask Paul” videos.
A recent video related to a question about revealing speakers.  Paul mentioned a couple of brands that he considered musical and wonderful sounding but not particularly revealing.  Paul’s definition of revealing was their  able to communicate subtle but discernible information that cables or other such changes might bring.
I find that I’m unable to discern many of the differences others routinely describe as obvious. I never attributed my inability to my M4’s and I’m not questioning them now, but I am curious if other Spatial owners consider their speakers to be revealing as Paul defines it.

The X3's I had a while ago were perfectly capable revealing differences in cabling. 

[Daryl Zero]

I bought the X5s after trying Magnepan LRS and then the .7s. I found the X5s to be as revealing as the Magnepans with added dynamics.

[thestatman]

My X3 special editions are very, very revealing.   Can pick up differences in tube lots to craft best sonic signature.   The only thing that beats them is highest quality electrostatic speakers that are crossoverless from 250Hz up.   That singularity of soundfield with no crossover is addictive for those with a long history of exposure to 'stats, even for something as good as the X3.

[Mr. Big]

My M3 Sapphires can sound as tube/natural warm as a 50's recording or as hard and aggressive as current overproduced compressed auto-tuned recordings, and everything in between. Change one power cord, and you will hear its impact, the same goes for speaker cables, change the AC outlet, and you will listen to that change without trying. These speakers only give you what you feed them and they will let you know easily the path you are going down. The reason is this design does not overpower your room, it works with your room, the bass does not take over and color the sound, and the bass produced is tuneful, fast, and tight if it is on the recording.

My preamp has gain adjustments of 0db, 6db, 12db and 18db. Now each setting has its impact on the recording even if you match the output SPLs. My speakers easily produce the sound quality changes of each setting, Odb is very clean and detailed but lacking dynamics though you can play it loud, much like a passive preamp at 0db, 6db Now you gain weight, color, presence, and bass, 12db you gain a very robust sound that with mono recordings is special, 18db more heavy bass and a flatness to the sound. You can hear the sound of the recording room, a low electrical hum in the recording, and even on a classical piece, you can listen to pages being turned during the movement. My preamp has a phase inversion switch and many recordings are out of absolute phase, these speakers make it easy to hear when the recording is wrong, i.e. Jazz at the Pawnshop comes to mind. 

My Quad Electrostatics could do this also, but the M3 sapphires are the Quads on steroids. For a speaker to be able to do this you have to have a speaker with very low distortion and a system with a very low noise floor and of course the room and its acoustics. So I would say after 40 years in this hobby these speakers are reveling, yet musical and enjoyable without the fake hyper detail of many designs which I equate to turning up the treble on a receiver. Spatial Audio speakers past and current (maybe even better) are a solid design and worth every penny asked today you see small-way stand mount speakers with limited bass and dynamics going for $22,000.

[Jimman]

I have the x5s and I think they are definitely pretty revealing. Between both my amps there is certainly a little difference. I find them on par with the focal Electra 1028be I had awhile back.

[Mr. Big]

Electra 1028be was $22,000. That says something about how good Spatial then and now speakers are.

Paul seems like a nice guy, and I'm sure he's knowledgable, and I haven't seen the mentioned video so am going off only the rough paraphrase of the OP's post (let me see, can I think of any other caveats?), but a speaker's ability to reveal changes in cables seems an odd metric for determining their ability to reveal detail in music.  I get it - if the speaker is sensitive enough to reveal differences in cabling, then it should, in theory, be capable of revealing detail in a recording, but, it seems to me, it ain't necessarily so.  A different cable may alter the sound enough to be noticeable through your speakers, but that doesn't mean more detail, nuance, subtlety in a given recording is going to be heard.  Volume, coloration, boosted treble or bass, are not only not necessarily indicative of the greater detail but may in fact occlude detail.  So, again, while it may be possible that a speaker's ability to register differences in cables or what have you, it's hard for me to see how that in any way necessarily translates into an assurance that your speaker is capable of revealing important details in a recording.  I suppose the only way to know for sure if your speakers are revealing is to compare them to other speakers in your system.  If you hook up a different pair of speakers in your system and suddenly hear elements in the recording you weren't hearing with yours, then your speakers are not as revealing as they could be.  Or, if you have a recording you know inside and out, so you know what should be there, and your speakers are giving you everything you know to be there, then your speakers are revealing, at least to the extent of your memory of the recording.  I don't think this is just a difference without a distinction.  That your speakers sound different with different cabling is just not the same as your speakers' ability to reveal music.  I'm not trying to be a curmudgeon here.  As I said, it just struck me as an odd metric.  And, for the record, I find my X5s to be, especially given the limitations of my room, as revealing as is necessary to communicate the music.  They're not what I would call hyper-detailed or clinical, but, if it's recorded well, I can follow the various parts in a vocal or jazz ensemble, pick out and follow the oboe, clarinet, violin, viola, cello, or bass in a symphony, pick out and follow the parts in the Act II closing septet of Mozart's Marriage of Figaro, and clearly hear the myriad electronic constellatory sounds of Florence and the Machine's Cosmic Love.  I guess, in short, yes, I consider the X5s to be revealing.

My system is very revealing and is sensitive to cable changes so much so that a friend and audiophile calls my system the truth. 

I did a home audition of an older pair of Spatials  that I took in from Paul Speltz with Anticables.  My Magnepan 1.6's blew them out of the water which some people did not like when I posted about it, even questioning me.  The maggies were way more musical and they were more resolving.  I had several audiophile friends over and they heard the same thing I did.  I really wanted to like them and move on from my 1.6's.  I even bought a pair of PSB T3's but alas the 1.6's sounded better and I sold the T3's to a friend.  Maggies with the right electronics and dual subs sound awesome.

Now I would love to audition some of the new Spatial speakers.

[doggie]

I have owned a pair of X5's for several years. My front end is a Lampizator Baltic 3 and a Linear Tube Audio Ultralinear Plus integrated amp. I find the speakers to be very musical with detail and realism moving into "spooky" good territory.

[Mr. Big]

I am still surprised by how good the Spatial Audio M3 Sapphires can be. Just updating my positioning of them the other day bringing them closer together to maximize my room in my loft by bringing them a bit closer together, I now have imaging a foot outside of my speakers on recordings. The bass became even more dynamic and the mid-bass improved which supports the midrange and highs. I will set my sights on trying one of the newer designs by spatial audio, I like what these speakers are capable of after trial and error of learning the impact on placement and room size, etc. There are no cut-in-stone rules in speaker setup because every room is different so you have to roll up your shelves and do the work to learn how any speaker interacts with your room and the "sound" that it brings.

Magnepan LRS’s were my gateway drug to dipoles. I loved everything about them except the flat dynamics and limited bass. Bought my M3 Sapphires and compared them head to head with the Maggies (I didn’t want to sell them until I was able to do the comparison- I loved them that much). All the things you’d expect the Spatials to do better were in fact better. BUT, the big surprise was the treble. Compared to the Spatials, the LRS’s was grainy and coarse. I was really taken aback because the higher frequencies were something I loved about the Maggies.

[Teenage diplomat]

My M4 Sapphires are very resolving.  I’ve been startled repeatedly hearing details previously unheard in LPs I’ve played many times through other speakers (most recently PSB Imagine T3 towers).  In fact, I’d rate them the best I’ve  heard in my fairly small rectangular listening room.  I have recently installed an Elac subwoofer to increase bass slam, but other than that I have no plans to change as I’m very happy with the realism and musicality of this speaker.

[Bingenito]

The latest version of the X4 with 2.5 way crossover is in no way overly revealing. I found it more laid back and relaxed than earlier versions of the X4 crossover design.I say that having tested them with various amps and room treatments.
