Have the W4S DAC-2 paired with PWT and Bryston BDP-1. PWT coonected by I2s and the Bryston transport by AES/EBU. I am very happy with the performance of the digital sources. My understanding from what I read is the W4S DAC is pretty close to the first version of the PWD, but the MK-2 is a big step up. With the Bryston, I don't really need the bridge. Guess I'll need to audition the new PSAudio DAC.
