Official OPPO BDP-105 Owner's Thread

^ It's just not feasible and extremely difficult to carry out DSP operations in a 1-bit bitstream. I don't even think recording studios (most of them) are doing it. Typically, audio is recorded in PCM, then DSP operations are applied, then convert to DSD for SACD mastering. I believe "Blue Coast Music" is recording direct to DSD, however.

Playing multi-channel DSD files
As an experiment, I have downloaded some sample .dsf files that are claimed to be multi-channel DSD recordings (something confirmed when I check the metadata settings). However, all my attempts to play these files on my Oppo DSD-105 have only generated a stereo signal. I have no such problem when playing multi-channel SACDs.

Does the Oppo not support multi-channel DSD files?

David


EDIT: I note that the input specs for the 105D on Oppo's UK website mention "up to 2ch/2.8224MHz/5.6448MHz DSD", so that seems to confirm that my 105 can't do multi-channel DSD. Is that likely to be added via a future firmware upgrade?

^ Read more carefully. That's the spec for feeding DSD into to Asynchronous USB DAC Input, which IS limited to stereo.

Playing media files from an attached or networked hard drive DOES support multi-channel, normal rate DSD.

While on this DLNA and DSD topic again.....

I'm using Foobar with the UPNP and DSD plugins. Using a NAS drive with Twonkey. Having problems streaming DSD to Oppo 105. The Foobar UPNP controller shows it's streaming PCM when playing DSD files. Oppo receives and plays fine. Not sure how to tell Foobar to stream DSD instead of PCM. I've messed around with the settings in Preferences, but nothing seems to work as it still shows PCM.

Are there any instructions on how to configure Foobar to output DSD over network??? I'm stomped!

^ Can't you just tell it to NOT transcode the DSD stream? In the JRiver DLNA server section of the app, one can set an option to push audio files to a renderer "as is"; no transcoding.

If it's there, I don't see it. I'm very confused by the menu system and terminology. I think my NAS is "the server", My Oppo is "the Renderer", and my Foobar is "the Controller" - am I right???

Most of my SACD's are ripped to ISO files. Foobar can open and play the contents fine. Historically, I've used HDMI to connect my PC to my Oppo, so DSD wasn't possible. Foobar converted to PCM and sent to Oppo. But now I want to try UPNP so I can have Oppo receive and play DSD without conversions to PCM.

When I play a file in the ISO, the Foobar controller shows PCM going to Oppo. Then I downloaded two DSD files (one dff and one dsf) and these don't play at all. No error message either. When I hit play in Foobar, it just says "Play Stopped". So somehow it's converting the individiual files in the ISO to PCM and sending them to Oppo, but not the dsf and dff.

Thanks for the help!

^ Twonky is your DLNA Server running embedded on your NAS's microprocessor. I wish I could give you some effective solutions for your equipment, but I have never used Twonky or Foobar software. I've heard that minimserver running embedded on a NAS supports DSD. All I can tell you, as it relates to your Oppo player with regards to DSD is that the 105 can't parse DSD .iso files. It needs to see either .dsf or .dff container formats for dsd audio via your home network or attached usb storage. I don't recall whether it was you or some other user who mentioned using the hdmi input on their 105 to playback audio, but the hdmi input can't receive dsd audio, only LPCM formats.

On rechecking that Oppo specifications page, I now see that I was indeed reading the second line of the 'USB Audio:' description. However, that DSD spec was in bold text and looked like a standalone entry, so I never read the line above! It was also late at night here in the UK and my brain had already commenced its shutdown process...

That same late night syndrome may also explain why my initial attempts to use multi-channel DSD files always played in stereo. This morning, my multi-channel DSD files play in surround sound! I'm not aware of having done anything different from what I did last night, so it is rather puzzling.

BTW, where does Oppo document the BDP-105's DSD capabilities via local USB or network connections?

I can personally confirm that I'm able to play multi-channel DSD64 (.dff and .dsf) streams via directly connected USB storage devices. And via UPnP and SMB network connections... The multi-channel DSD bit-stream is passed from my Oppo via HDMI to my Onkyo amplifier
