There's kind of an interesting "exchange of ideas" between Soundhound and Willscary concerning "break-in" in this post http://ubb.outlawaudio.com/ubb/Forum15/HTML/001216.html

Willscary refers to receiving his 950 and he thinking it was "brighter than his NAD". But after awhile it seemed to change during a "break-in" period it and how it got got "smoother and sweeter".

As a prospective buyer in the near future I'm very interested to see how it turns out for your brother.

Keep us posted.
