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 had a pair of 703 that I "broke in" for 4 months, still harsh, even with tube gear. I ended up selling them.
i go with 1st impressions,if i hate a peice of gear as soon as i get it its outta here,i had the same experience with b&w speakers,i dont think your sound will change enough if your unhappy right from the start.
Thanks Bojack, Gretsch6120 and Tvad. I'll give them a chance to surprise me...If the sound continues to be harsh after 1o days, I'll do an upgrade to audience 52 or something else. In the $1000-1200 range, which loudspeaker do you think really stands out?
Yes, give them time. If B&W is still using Kevlar drivers, it is pretty stiff out of the box. They also use a rubber material for the surrounds instead of foam, which needs to loosen up.

I own 5 pairs of B&W speakers (out of many more pairs). None of them sound bright and harsh...

B&W speakers also tend to be pretty neutral. So while some say change the speakers again and don't mess with the system (maybe); you could be spending the rest of your life looking for the right speakers to fit what may be a harsh sounding system to start with. What prompted the change in the first place?

It could even be many things in combination, including the sources, cables, even crappy electric power. Your favorite CD for demos may even be poorly recorded, and the old speakers masked it.
