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


I have been running 25+ year old B&W Matrix 803 S2 speakers in my 2-channel system for about 15 years, and I finally treated myself to new speakers.  Mock me for buying based on research alone, but I got a really good deal and just unpacked my beautiful Dynaudio Contour 60i's.  The Dyn's are not broken in, just starting to play around with different songs, but I am expecting an improvement out of the box, and not getting it.  They are no more revealing, and slightly harder and more jangley in the mids and highs.  The bass is of course much better with the big Dyns, but the B&Ws with the Dyn Sub6 subwoofer I was running were better.  I have very good equipment so it is not a matter of driving bigger speakers (ARC Ref preamp and Bryston 7bSST2 monoblocks).  Unless speakers get A LOT better with break in, I thinking these Dyns may be converted back into cash.   Thoughts? Thanks.

some speakers really demand strong solid state amps to sound their best, tube amps cannot handle them

other speakers thrive on tube amps, presenting more friendly loads and efficiency, but to be as efficient and amp friendly, they sacrifice some performance parameters (while excelling at others)

when one starts out in this hobby it is most important to find the right speaker for your room, your listening, your music - then treat the speaker as the given -- and mate the amp to handle the speaker and deliver the best possible sound from said speaker

as you move along in this hobby and hear what different speakers and amps (as combinations) can do, you start to become more open to changing to different speakers that can in turn be driven by sweeter, more palpable sounding amps (be they tube amps, or lower wattage simpler ss amps)  to deliver a nature of sound you like better

it is an experiential, iterative process
I just bought a pair of dyns and they were awful and lifeless out of the box. Played them two days straight in a closed room. Entered the room after the two days and shocked at the difference in sound. The dyns became much more open but a bit harsh. Played them a 3rd day for 8hrs and their was not a hint of harness. 
For glissando, no the B&Ws have not been serviced - thanks for the call out.  I had no issue with the B&Ws, just wanted the indulgence of newer, better speakers.  If I keep them, I may get them checked out.  
For jjss49, thanks.  Based on my somewhat limited understanding of electronics, the Dyns are power hogs, so big SS amps are desired and what I have.  Now, I have read some so-so reviews of this model (7bSST2), so that will be on my mind...though the system sounds pretty good now.  To your point, I have a sense that with age I will move to quieter, more refined components, but for now, we are going with big and brash!
For dwest, yeah brother, harsh was the word, but world of change now, and I still have a lot of breaking in to do.  I am a Dyn convert.  Enjoy yours!

Speakers must be "broken in" just like car motors and new shoes. They are electro-MECHANICAL devices and need "experience" to limber up. Even wires need a bit of break in. I did not used to believe it, but experience has taught me. Thank God I'm still teachable. Put on a good FM station and go visit friends for a few days. Keep smiling!
@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.
