Revision as of 16:24, 5 February 2010
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 NJM4580M or AZ4580 operational amplifier on this picture

The logotype seems to match this one:

AZ4580 Monolithic dual low noise operational amplifier(pdf)
But the numbering matches this one as well
NJM4580 Dual 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.
Review of Dune BD Prime 3.0 by stereo.ru Jan 2010 (pdf)
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.
http://www.twistedpearaudio.com/digital/buffalo.aspx Buffalo II is a semi-DIY kit. It is quite expensive but should deliver insane performance.
