Having the same issues with my new Rega Brio R. 4 days old now and about 50 hours on it. I am really hoping the bright and hard upper midrange and lower treble become more round and warm soon. I will give it 200 hours. If it does not change I will return it. Everyone hears different. Some hear better than others in this area. Maybe my ears are just sensitive. Great amp otherwise! So don't don't let my posts deter you from trying one out.
