Instrument separation, staging, and microdetails. The overall signature of Hadenys and Noire X seem complimentary to me, I think Hadenys is closer to Noire x than E3 is to Noire X (my memory may be faulty). Overall airy, not really fatiguing, neutral bright.
The Hadenys don’t have a bit of that metallic sheen?
