Here are some first impressions on my Nerva X posted on FB.
Hello folks, I thought I'd share some initial impression on the beautiful Nerva X from HYLA.

I just listened for a couple of hours at this stage, so this is really an initial feeling.
Obviosuly, they are a marvel to look at, and very comfortable, not too large. Another good thing is that the sound is NOT very tip dependent for some reason, which is less of a hassle. I settled on the JVC Spiral Dots at this stage.
The general philosophy here seems to be musical and refined. Visceral, well-grounded and control bass, smooth and clear mids, non-aggressive yet detailed highs. Staging seems excellent, not excessively large but reasonably so with excellent imaging. They overall tonality is on the warm side, with a lot of realism.
The thing that strikes me the most is the smoothness of sound and transition between frequencies. The people at Hyla sure know how to tune 10 drivers in a coherent manner.
It might benefit from a brighter / airier source (which I don't really have), but with the WM1Z, I am going all in smooth musical full bodied and it is nice.
