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

Thanks again for all the input.   I have some tinnitus in my ears, and it is triggered by harsh sounds or a poor recording, and is muted when listening to nice hifi audio.  The 60i's are maybe 8 or 10 hours into break in now and the tinnitus fires strong as soon as I enter the room.  They are definitely more harsh in the mids than the Bowers.  My wife noticed it too; when she first came into the room in which they were playing, she commented on distortion (she is not an audiophile, but noticed a degradation from the old speakers).  Unfortunately, the advice from this group seems pretty mixed - plenty of indication that I will see real improvement over time, plenty of indications that first reactions are probably not going to change that much.  Oh well, on with the journey...continue to break in, make a decision at some point.  

To gosta, the 803's are an mid 90's speaker...not sure what they cost new, one post said $3000.  I would expect $10K 2020 model from Dyn to be better, but that question is open.....

Thanks again - appreciate this community

Given the general stagnation of speaker design (there are exceptions) you could only really expect the Dyns to be different, not necessarily better.  A high percentage of modern speaker designs incorporate a (somewhat) tilted up mid-high end, perhaps because modern taste favors the kind of "detail" that this can give the impression of, perhaps because it makes them more impressive in brief showroom demos (think: how big box stores adjust the settings on TVs on demo).  What you're hearing may ameliorate a little, but it won't go away, it's built in to the speaker.

Harsh mids may come from unwanted reflections. Placement of the speakers and yourself is most important.

Yeah, I sort of ignored the fact that a lot of people have been talking about room...and there could be something there.  Some of the sound issue I would call ringing, which (to my untrained thinking) seems consistent with a room issue.  Not sure what to do with that; this is not a dedicated audio room, so I can't move them much or start adding foam to the walls.  And the fact that the B&Ws were running in the same place without this issue seems important; whether or not my room is optimal, the old speakers did not ring.  I may finally be getting "what type of music you listen to" with speakers.   I EXPECT exquisite refinement on vocals and strings when I want it, but most of my listening is rock/metal.  With a high quality heavy recording (e.g., Metallica black album) the Dyns sound incredibly good.  WIth more delicate fare, they seems a little ragged and ringy in the mids.
