| The general idea is to put some stuff about the Audio-hardware of the Dune BD Prime here:
| | Welcome to discuss whatever you feel is missing or should be clarified on the audio section of the Dune HD and BD players. |
|
| |
|
| ==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==
| | I wonder if I could take it out of Dune and attach to C200 Sigma board. Hardware aside, there would also need to be software components... |
| 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

| | |
| ==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.

| |
| Buffalo II is a semi-DIY kit. It is quite expensive but should deliver insane performance.
