I own ATC SCM40s and am toying with a change. I'm wondering whether I can find a lot better in the £5k ($6k) price range.
The replacements would have to be aesthetically friendly too, which in my room means white or wood.
I've not seen many measurements for SCM40s, aside from:

I'm not sure how reliable those measurements are though.
I've also seen mid-dome measurements, including the ones Troels Graveson produced, which do look excellent:

I'm considering going all in for ATC active SCM40As, or I could stay with my passive SCM40s, or I could go with something else entirely.
Ultimately, I'm after the most transparent speakers possible, in terms of in-room performance, when placed about 12" out from the wall.
You're going to recommend Revel now, aren't you? I certainly do want to listen to the F208, but unfortunately black speakers won't work aesthetically in my sitting room. I know the F206 comes in white though, so that's a front-runner.
I suppose the difficulty is, without measurements for the SCM40s, I can't tell whether any speakers in its price range perform better. That leaves relying on a) subjective impressions, and b) assessment of the quality of driver materials/construction. On both those fronts, the SCM40s seem to excel.
Look, going to say some stuff that ppl are not going to like...but...
Amir has tested 2 speakers recently that measure extremely well on the spinorama test, yet one has extremely low distortion motors, and the other average.
Subjectively, for amir at least, the low distortion won out hands down.
The human ear is most sensitive to the 700-7khz range.
The big ATCs use the SM75 mid dome. (Or SM75s for higher efficiency)
That dome measures very low in distortion and is capable of big SPL cleanly.
It's a monster. I have measured it, but do not have the measurements available as it was on my old dead PC. I know it has been measured by others, so will take a look for it.
It plays from about 400hz to 4.5khz (ish?) if memory serves.
From my tests (I bought and sold many speakers to try out + measure over 10 years), my own preference correlated with low HD.
Uneven Freq response on axis can be EQd, distortion cannot.
I'm not saying ignore the spinorama, I just have the feeling you might be in my boat, so just make sure you listen to somthing before you buy it, because you will struggle to get significantly lower distortion than your current speakers.
*Edit*
There you go!

If that really is at 110db, it's VERY clean....unbeatable?
1)Can the revel meet that? At that SPL? Ask amir, but I would guess not.
2) What could? Perhaps the new celestion AX radial compression driver? Or a JBL 2450SL. You will need a huge horn for these though, and I assume we're stuck with a small boutique design or DIY build for these.
All things considered, unless your SPL requirements are that high, The safest blind purchase would be a Revel IMO. The 3 way Focals are worth checking out though.
Having bought and sold everything from SCM35's to Quad ESL63's, R600's, L100 century+others, Trangle, Tannoy, B+W, paradigm, monitor audio, Dynaudio, and Maggies, I settled on some focal Electra Be's. They also measure well in term of distortion (and dispersion) , and had the SPL abilities that I needed (as it turned out I needed more SPL than most)
The only ones I could live with out of all that and many many others are the ATCs or the Focals.....I went DIY in the end though myself. Note, the ATCs needed EQ as they had 'enhanced' false detail (peak) in the non active ones if I remember right.
