Quite a nice review. I concur with most of it, except the technicalities part. I cannot entirely comprehend what you said regarding the layering, but to my ears, the layering did sound quite well done. Can you perhaps explain with an example?

I also completely disagree with you regarding the comparison with Autumn. Although I do not have it now, when I did, I remember I was nowhere near as impressed with it as I have been with OD200 on the technical front. OD200 is considerably above Autumn in my ears. But then, we might hear differently.

@Ace Bee , if you listen to orchestra, ska and jazz tracks, you will notice it, as I mention I noticed that that I perceived that there are 2 layers instead of 3 or more which in which should have. Try to listen to Dvorak: Symphony 9 or Felix Ayo's Vivaldi album. Of course we should remember that DDs will not always give the best layering performance compare to hybrid drivers in my opinion.

Autumn has larger sound stage, better resolution but its weakness is its layering aspect which I already pointing it out in my both review on this one and the BQEYZ Autumn Some reviewers will agree on my findings. I still consider the Autumn as one of the best single DD besides Tanchjim Oxygen and Moondrop Kanas Pro and probably has still an edge of some of it technical performance like soundstage and stereo imaging.

But at least, despite of its not so refined layering aspect, OD200 is able to manage and capable enough to play a complex multi-instrumental tracks.
