I have the Bryston BDA-1 and the W4S DAC2 and agree with Sboots in that if you aren't using the USB input then the Bryston is superior. I find it extremely musical and more analogue-like. And the AES/EBU connections are the way to go, regardless of the DAC/Transport.
I also have found that digital interconnects do make a huge difference. The WyWires are the best for the money IMHO.
