Pleasurably better, not measurably better

Even if the Cornwall's do other things better, the more neutral 15s allow you to hear the differences between recordings better. 

I've not heard Pure Audio speakers in a very long time, and certainly not these models.  I am however always skeptical when someone says they switched speakers to hear more.  It's usually hearing something DIFFERENT than they did before.  Not saying he's wrong, but this is a claim I've seen a hundred times from a dozen reviewers and IMHO neutrality was not the reason.

holmz but if one is listening to music, ears are NEVER removed from the equation. Hence the real real-world artificiality is when one depends solely on laboratory measurements that have cut the ears off.

this (below) mostly covers it:

One can have the same exact music playing on the same system, and every time it can have subtle difference in what we perceive and focus on.

It is like a magic trick at a dealer’s shop, when they say listen to the “shimmer of the cymbals,” that is pretty much all we hear.
We are so busy focusing on one hand, that the other hand can literally pull a rabbit out of the hat or thin air.

So it is not so much that we all hear differently, it is more like we all focus differently, and the same person can change they’re focussing on.

At least with measurements we might get to the point where we find that all of the ones with certain squiggles we either like or don’t like.

And we are not likely to be fooling anyone, as the majority of people seem to find a set of gear either sounds good or doesn’t… and they quickly can acclimate to the sound. And that some measurements correlate with good sound.

To say that the ears are all different would be like saying that the feel of a block of ice or a hot stove is different because all people “feel” differently. I sort of doubt it.
Maybe it is possible…
But I would like to know the temperature, of say a bath, before I get in it… then over time I might find I like 95F water better than 50F or 130F.

Lastly; I do not mind know knowing that my gear is technically inferior, and that I still like it.
I am not going to be listening to graph paper… even though I know some people can read sheet music and hear the sound in their head. For them the ears are not even involved… much like Beethoven and other composers can be partially or totally deaf.

When we see high noise values we can pretty much expect to start with a system that will be hissing.
And when we see a spray of harmonics, like the 4th through 10th trailing out to the right, we know it is not count to be smooth and warm, and we know it before the Beethoven even starts playing.

Arguing about the relative level of 2nd and 3rd harmonics is like comparing the bath water preference of 90, 95 and 100F. Or why we have salt and pepper shakers on the table.

Everyone’s tongues are not that different, some people just do not care for too much spice.

@erik_squires ​​​​@cd318 , +1 on ceiling absorbers. I have absorption panels on the ceiling in the front 1/3 of my room (you can see them a bit in the photo in my profile) and I use Auralex Geofusors back filled with absorption (polyfil) so they double as a bass traps over the MLP and on the ceiling in the back of the room near the corners. They work really well.

I do both measurably and pleasurably better. First I made the room measurably better. Then I added immersive audio capabilities for pleasurably better. Depending on the source and the recording I can "increase" the pleasure of the music by changing sound modes ( Stereo, DTS-Neo-X, Audyssey DSX, Auro 3D, Atmos, etc)

I haven't tested my system for it's distortion, although I suggest it is low (the speakers have very low distortion (under .4% at 35 Hz).  However, I am astonished at the differences in sonic texture of different recordings with close miked jazz maintaining the least differentiation in sound (especially Rudy Van Gelder recordings).   The range of sound is as wide as the colors in the rainbow (that's very wide).
