I think a DAC like the Bryston BDA-1 might help. I experienced some harshness in my system with B&W 803d speakers (those diamond tweeters can be very revealing, both good and bad), particularly with female vocals, when I had a CA 840 CD player. When I added the BDA-1, playing native 44/16 from the CA, a lot of the harshness went away. I suspect the op-amp analog output stages of the CA were to blame, as the Bryston has a discrete Class A analog output stage. So I am suspect when folks say its program material, because the same CDs now played on a PS Audio PWT via the BDA-1 have never sounded smoother, all harshness is gone.
