Thank you for your answers,
I will try to give them another 100 hours and maybe play a bit with cables to see what this will do to the sound. Definitely I do not want to change them so easily.
I work a lot, have family and I do not have some much time to listen. Maybe it was naive from me to expect that they will sound perfect right out of the box. I have time to enjoy my hifi for about 3-4 hours per week, so my Dyns were active about 50-60 hours since I bought them (they were new).
To answer Callas. I have auditioned them in the studio paired with McIntosh MC220/275 and they just sounded perfect. Unfortunately I do not have 8000€ to buy 220/275, so I tried Ayon, and I am trying to find similar sound.
