Reference 6 break-in

[RLF]

Although my new Ref 6 sounded great right out of the box, I found it to be a little bright and edgy on some of my recordings that didn't sound that way when I had my Ref 5SE in my system. I did have my dealer's Ref 6 on home audition for a week and didn't remember it sounding bright or edgy. Therefore I've started running my new Ref 6 for about 12 hours a day to accumulate more hours on it. I'm now at 137 hours and find it much more relaxed sounding and more like I remember my dealer's Ref 6 sounding which had about 250 hours accumulated on it when I auditioned it. Of course ARC recommends 600 hours for full break-in, but I am curious what other Ref 6 owners have experienced with break-in. Thanks.
