Midrange/treble harshness at volume


I have a Hegel 160 amp. Cambridge CXN v2 streamer and Bryston Middle T speakers.
When I listen at volumes up to about 75 db I love the sound, when I turn it up 80-90 db I find that the midrange and treble become quite harsh and un enjoyable.
I have a small room 12 x 13, could it be room issues?
Thoughts?

Order a pair of free standing GIK 244 panels for first reflection absorption.  I had the same problem and the 244 panels fixed it instantly.
