My english is not top tier, so with google translator, sorry;
First impressions of Noire X; the first thing to say is that Sash Tres SE serves here as a comparison point, which is an open planar. Which has been listened to quite a lot now. So my ears are still in ”Sash mode”.
After all, the soundstage in Noire x is really good; airy, open and reasonably dimensional. That's what i was looking for, a cramped soundstage doesn't please me, it has to have air, lightness and dimensionality.
I was afraid that i would get too much bass again (as happened with the Fiio FT1) based on the measured response, but again it was seen that the measurement tells quite a bit about reality. The bass comes from these the same/less than the Sash.
The measured response in terms of bass is pretty close to Fiio, but the reality is quite different.
A little juiciness runs out from the middle area, more like a dry one. Even thin sometimes. The same way I would describe the upper end; the support is a little tiring.
The reproduction is cleaner across the board, the small disturbing graininess of the Fiio wears out.
I would like more of that general juiciness though.
And that DCAs are praised for their low distortion? If so, it would be interesting to see Sashi's distortion values.
But yeah, i have to give them some time now and maybe the "burn in" will play a part, even if I don't really believe that.
But if i now compare my own first impressions and the online hype Noire got with Sash, then Sash is indeed a top-class headphone.
Noire is a very positive surprise in terms of soundstage.
5 times the price of the Fiio FT1 is looking for some justification, but there is quite a lot of difference in sound from Fiio. Whether it is worth the financial investment is up to each person.
But the sound of these is such that it doesn't hurt in those moments when you "have" to use closed backs. However, there are quite a lot of those moments in our household. And the search was specifically for a headphone with an airy, reasonably large soundstage and good isolation from the sounds of the environment. Both of which are confusingly good in Noire.
However, Noire gives you the opportunity to enjoy high-quality sound without disturbing the surrounding noise. Or that I would disturb others with my earphones.
And you have to remember that the exhaustion of the Wau effect in the first meters is usually a good sign.
Edit: if Noire X was put on blindly, I'd say it's open. The sound image is better than many open ones. Also in terms of accuracy and 3D.
Edit: correcting my statement, NX needs more volume. When it wakes up we are talking!

To be continued as listening proceeds...
