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

Signals fed from the Main Board

And the Audio DAC-board itself

General layout

To my best guess its the Cirrus Logic CS4344C DAC and a NJM4580M operational amplifier on this picture

CS4344C and NJM4580M

Performance

RMAA, other audio measurements?

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.
