Awful sound from B&W's: Break In needed?


I've bought a new pair of B&W 602 S3 and they are sounding awful with my COnsonance CD120 and Arcam A80. I think they need a lot of breaking in, or otherwise something is wrong with my system. The sound is harsh, and the midrange is shut in. Have you guys experienced something similar? Can I expect to get a really better sound from my speakers after the break in period?

I agree with Sugarbrie. I have had 3 sets of B&W speakers and none sounded bright or harsh.

A friend brought over his Signature 805's one time and I liked them so much I sold my speakers and purchased a set. For the first 4 days they weren't even close to his and if I would not have heard his first I would of thought I made a mistake. I let them play 24 hours a day and if nobody was home, I'd play them loud.
Do make sure they are wired correctly; I had this problem with a pair of tannoys. Very harsh treble and brittle sound that made them sound like crap. The midrange was very strange and basically I hated the speaker. Found out my amp was sending out a reversed polarity signal.... Reversed all the speaker wires and wow, my speakers were alive for the first time.

I don't have the amp anymore, but it was a NAD.
I was just going to post that you should check the polarity or phase of your system as Rtilbury writes. If the speakers are out of phase, the sound will be harsher than normal.

Check every component. Many preamps are out of phase.
What did you have before that wasn't harsh though was lacking in some way?I never thought that B&W was garsh or strident (the wayu I an many others foun much Thile stuff is too brite).You may need break in but if the impression is this strong it's more I thin that it's system matching (you liked them in the store you bought them)But maybe it's your gear,your room ,or simply you were wrong about fisrt impression you had at store.Ask store about problem fi you ca reurn with re-stock fee or a trade fro soemthing else you think ,again,sounds good in the store.But you get it home and more bnad sound occurs you 1)have a problem with your electronics 2)have problem with room 30 are anal (overly) about what you should be getting for your investment 3) You are simplay psychotic.Nut the dealer should be there to solve problems and make you happy so talk
Hi Chazzbo,

I bought the entire system recently, so I am just supposing that the harshness is not caused by the A80 or the CD120...do you think it is possible that the problem is in the amp? I am sure that I am not psychotic about the bad sound. I had a good system in Brazil, before I came to the US, and the sound was more open, warm, and pleasant to my ears. I had a rotel 965 CD, a Pioneer A400 amp and B&W 804 speakers.
