Have not heard the Bryston DAC ( have the BDP-1, which is a terrific product with fantastic support) but have the PWD MkII (now superseded by a new PS Audio DSD - capable DAC). It is an excellent product. I have had a number of CDP's and DAC's over the years and this is by far the finest, most versatile and dependable sounding DAC (meaning it does nothing wrong) I have had. Used price now will be dropping, making it even more of a bargain. Plus, it is beautiful to look at.
