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.

I think you are describing the ‘tilt’ in speaker sound that many manufacturers are leaning towards. 
The Brystons won’t be helping. Try an ARC power amp - much smoother and more natural in mid / high frequencies.

They sound beautiful with Dynaudio, although the bass will be a touch softer, but in a very pleasant way.
My ARC preamp made a big step up in soundstage from Bryston BD26.  I imagine nice ARC amps would round out this system, but so many tubes....and a big price tag to get the effortless power of solid state.  I wonder if there are SS amps that would adjust in the right direction...Halo JC1?  The search for the next tweak goes on......
@mathiasmingus  I tried a respectable tube amp on the speakers and though it sounded very sweet, it just didn't deliver the "slam" that I want.  Of course, amps are all very different from one another so I can't speak for what an ARC amp would do or any number of other great tube amps.  The Contour 60i do demand some current to make them come alive and deliver what they are capable of.  I settled on a SS amp that has a softer sonic signature than most.  I bought a Balanced Audio Technology (BAT) VK-255SE.  I also use the very well paired BAT VK-33SE preamp (lovely tube preamp).  It's a wonderful matchup for the Contour 60i.
So the bottom line is, if you are finding the Contour 60i speakers are delivering what you had wanted then at some point make a change in your electronics that will better suit them.  You have the preamp, just get the right amp to address the sonic signature that you desire.  And yes, a very good power cable and signal cables are very important in delivering what any electronics have to offer.
Enjoy the fun ride!
