The general idea is to put some stuff about the Audio-hardware of the Dune BD Prime here:
Overview
The audio section of the BD Prime is relatively simple. 4 parallel stereo DACs make up the audio from signals passed from the main board.
Hardware
Signals to DAC-board
And the Audio DAC-board itself
To my best guess its the Cirrus Logic CS4344C DAC and AZ4580 operational amplifier on this picture

AZ4580 Monolithic dual low noise operational amplifier(pdf)
Performance
RMAA, other audio measurements?
All found so far is a review done by stereo.ru Jan 2010. Page 3/3 in the pdf indicates some graphs of performance. A copy can be downloaded from dune-hd.com.

Hardware Modifications
Can the current hardware be modified to improve performance
Can a replacement be fitted to create a real high end solution? There is a possibility that the Buffalo II will be able to slot right in without any problems.
