I had a high end Sherwood receiver (if that's not a contradiction of terms). Sounded like crap the day I got it. Sounded like crap the day I got rid of it. Funny, that one didn't get any better after I ran it for quite a while. I guess I just didn't psychoacoustically adjust to that particular unit.
I had a Cambridge D500SE. Sounded like crap out of the box. Let it run by itself for about 10 days. Still sounded like crap.
Got an Ah! Njoe Tjoeb 4000 CD Player. Sounded a bit thin out of the box. Let it run just like the Cambridge, by itself for about a week. Listened to it and smiled bigly. That one got much better!!!
My M3Tis, M22s and M50s all improved after breaking in.
Some components improve after breaking in. Some don't. Go figure.
