Does my Oppo downsample DSD to PCM ?

[Ned Kelly]

Hi All,

 

Upgraded my BDP-105D to the latest firmware (April 2014, from memory) and it will now play the .dsf file I downloaded from Blue Coast, but it appears as 'Track Type: DSD to PCM'. My settings are as follows:

 

Playback -> SACD Priority = Stereo

AudioFormat Setup

- Secondary Audio = Off

- HDMI Audio = Auto

- Coaxial/Optical output = Bitstream

- SACD output = Auto

- HDCD Decoding = Off

 

Audio Processing

- stereo signal = downmixed stereo

 

The Oppo is connected to an Auralic Taurus headphone amp via XLR interconnects - dont see why that would make any difference. I dont know much about DSD - clearly - but my Chord Hugo doesnt give me any feedback except for some colored lights, so I'd appreciate any feedback you can give me on this, even if it's 'RTFM !'

 

Thanks,

 

Ned

Doh - it was indeed an RTFM issue - my apologies:

DSD to Analog Output:

 

The internal DAC (Digital-to-Analog Converter) inside the OPPO player supports native DSD. You can connect the analog audio output of the OPPO player to your A/V receiver, audio processor or amplifer to get native DSD audio.

 

Please note that in DSD mode, the BDP-103 and BDP-103D do not offer volume control or variable output level. In this case you must provide a preamp/processor or A/V receiver to control volume before sending the signal to an amplifier. Only the BDP-105 can adjust the volume of native DSD signal. The following settings in the player's setup menu should be used:

 

Playback Setup - SACD Priority: set to Multi-Channel or Stereo based on your preference

Audio Format Setup - HDMI Audio: set to Off (This ensures that any connected HDMI device will not cause the player to convert DSD to PCM.)

Audio Format Setup - SACD Output: set to DSD
