have you tried tube rolling? Different tubes tend to give you a different sound. Maybe some EL34s for that warm lush sound, although you might lose some power at the low-end. Perhaps you could add a stereo amp to give the speakers more power then what that Ayon is giving as well as a tube change?
I heard the 380s with Audio Research gear and it sounded fantastic. One thing tho, and Im sure you know, is that Dyns typically try not to impart much of their own sound on the music. Sure they have a little warmth, but pretty neutral overall. If all you components are neutral then it could sound boring.
