Heya Chebby , see you have one too ,,, at the moment i'm finding the sound a little fatiguing to my ears , the upper mid/lower treble is a touch harsh.
Before this i was completely skeptical about burn in, but this box's sound is definitely changing over time.
Clocked up about 60hrs so far
My one spent a lot of time doing DVD and TV sound and Freeview radio duties (optically connected to the Panasonic in my sig) the first week I had it - due to not having much daytime spare-time that week. So if there was any 'run-in' it was all over before I got the chance to sit down quietly and listen critically to lossless material without other people around.
No fatigue here with my one. Far from it.
