Okay, How Important Is Speaker Break In? (Dynaudio Contour 60i)

@mathiasmingus  Glad to hear that you are now a Dynaudio convert.  I have long enjoyed the Dynaudio signature sound.  My new Contour 60i just keep sounding better and better (as you have found).  Just yesterday I went back to my new copy of Jennifer Warnes, 'Famous Blue Raincoat'.  That is an album that will really show how the human voice can sound with a good speaker.  When I first got my new Dynaudios I played that album to establish a reference sound for the speakers when new.  They sounded good, but somewhat strained and narrow on her voice.  Last night I revisited the album and WOW, what a difference.  The slow development of the speaker break-in process is typically difficult to notice, on a day to day basis.  But doing what I did with that album - playing it early on, waiting for a respectable amount of speaker break-in to be accomplished, and then playing the same album again - was a revelation of proof for the total process.  The sound quality last night was breathtaking, absolutely fabulous.  Jennifer sounded as if she were singing directly in front of me, live!  At the present stage you are with the speakers you can still do that.  Give it a try, using your best sounding album with human voice and also try for some wind/brass instruments. 
Enjoy the speakers.  They are wonderful.

so apparently speakers don't need to be sent back immediately if they don't sound perfect straight out of the box?  Shocker!  Someone better let Einstein in on this audio secret.

Yea,don't listen to millercarbon..hes a schill for Tekton and its now really obvious he hasnt a clue..maybe Tekton sound the same from start to finsh( could be the fact they use guitar amp speakers ie,eminence )but any quality speaker ive ever purchased sounded totally different after a correct breakin period.

In my opinion, you're just used to the way your B&W's sounded to you, for 15 years of use.  You're ears and brain may adjust over some time to accept the new speakers. 

I've tested identical speakers, one set new out of the boxes and the other with 2+ years of use on them and found no difference in sound signature. 

Overall, if you're not happy with the sound of the new speakers, you may never be.  At least you're in a good position with them so you wouldn't take a beating if you were to re-home them. 

Maybe a newer set of B&W's would benefit you.  (??)

I had an interesting experience with a pair of Klipsch RF-25s. I plugged them in and I thought, these really could be refence loudspeakers. Two days later they had lost their edge and now sounded like a very average speaker. So in this case the break-in made them sound worse. I was a dramatic change, never experienced anything like it before or after.
