Gawdbless,
What day did you listen to the signature diamonds. On friday they S&*%$d. They air fraighted in a brand new pair of speakers for the show. I listened to them on friday first thing. They only had 12 hours on them. They were shrill with bloated bass and flat mids. This was not a smart move on B&W's part. I listened again on sunday and they were a much better sounding speaker. I would like to listen again after they have about 500 hours on them.
