Considering that the Perfect Wave DAC can be purchased new for as little as $2,100 from some e-tailers (hunt around and you will find one), this should be a no-brainer. It is a great DAC that sounds wonderful using the coaxial digital input and is absolutely stunning using the I2S input. The latter can be accessed with the PW Transport or (when it is released) through the network Bridge. I owned the Ayon CD2 in a second system (now dismantled). The PW DAC + Transport sounded far superior to the Ayon. And many here on Audiogon carry a torch for the Ayon CD-2. If the PW DAC + Transport is far superior to the Ayon CD-2, I doubt the Bryston or W4S DAC-2 are better than the Perfect Wave DAC.
