It performs well for jazz and vocal but for classical pieces, some felt that they're not neutral enough. Besides this, B&W speakers are also generally famous to be used in a HT setup too whereby they can be driven hard without fear of damaging its voice coil.

I own a pair of DM600S3. I   have done comparisons with my current speakers. However, my amp can only play one pair of speakers and switching the speaker cables is troublesome. So, I am thinking of selling it off. 

I can send you the price which I am looking for. Hardly used the speakers. And I am also working outstation.  Only at home during weekends. So, no point keeping it.
