Dgarretson,
The Sonore board was designed with the Buffalo DAC in mind. It accepts both PCM and native DSD, completely isolates the USB side from the clean side, has its own oversampling filter (optional to use) which they claim is superior to that on the ES9018 chip (I'm still evaluating that), and can be run synchronously with the Buffalo board if so desired.
Here's a link:

It requires ~300mA to run and can be used with either a 5V supply fed into its own on-board regulator, or with a 3.6V supply bypassing its on-board regulator. I'm using a Salas Reflektor-D regulator set at 3.6V for mine. Sound is very, very nice...I especially like DSD so far.
