    Connect SBT To Oppo UDP-203 Blu-ray Player

    Firstly, I apologize if this is a silly question, but I have never used an external DAC before, only the SBT's built in one by plugging an optical cable into my Denon AVR.

    I've just bought an Oppo UDP-203 Blu-ray player which features a built in 32-bit DAC from AKM, the AK4458VN, which is an 8-channel DAC with support for formats such as 192 kHz / 32-bit PCM and multi-channel DSD.

    I'm trying to find out if I can run my SBT through the Oppo to take advantage of the AKM DAC. The majority of my music files are either 24/96 or 24/192 flacs from ripping my extensive vinyl collection.

    From the Google searching I've done so far I get the impression I can by connecting a coax cable between the SBT and the Oppo.

    However, that's all I can seem to find at the moment. I'm looking for more detailed instructions.

    Any assistance is greatly appreciated.

    Since when did a blu ray player have an digital INPUT? (Edit - seems that's exactly what it does have.. well there you go.)

    And, you are using the external DAC in your AVR if you use an optical cable from.the SBT to it.. Do the same thing to the optical in on the BDR and you're done.

    Looking at the manual, it's not clear to me that the Oppo can be used in the way you want. There are no S/PDIF inputs and the USB inputs on the front and rear panels are not the typical USB "B" type used for this purpose. Plus, there is no description in the manual of how the device can be used as a USB DAC for an external streamer. You might want to ask your question to Oppo customer service and post their response back here for others to know.

    Owner's Manual:
    This unit supports “USB Mass Storage Class Bulk-Only Transport” devices only. Most USB
    thumbs drives, portable hard disk drives and card readers conform to this device class. Other
    USB devices such as MP3 players, digital cameras, and mobile phones may not be
    compatible.


    There are other options:

    1. Assemble a Squeezelite player from a Raspberry Pi and use it to play from LMS into the Oppo HDMI input. This can cost as low as $50 and will support your 24-bit files; and, you can redeploy your Touch to another room.

    2. Buy a S/PDIF or USB > HDMI converter and link through it from the Touch to the Oppo. I'm not that familiar with these devices, but no reason it should not work.

    3. Use the DLNA capability of the Oppo by installing the "UPnP/DLNA Media Interface" plugin in LMS. The Oppo would need to be networked for this to work. It may not have all the features of Squeezebox, but it's something.

    It would indeed be more normal for a BDR to have digital audio OUTs than ins. I found a reference to the connection on the rear being inputs, but if that isn't what it says in the manual then they are almost certainly outputs.

    Thank you for your replies.

    I will give the optical cable suggestion a try.

    One other question - do I need to also connect a USB cable between the SBT and the Oppo?

    One signal, one cable.

    I don't think that the 203 model has that capability, but the UDP-205 ($1300) does
    https://www.oppodigital.com/blu-ray-...-Features.aspx
    USB DAC and Coaxial/Optical Inputs
    An asynchronous USB DAC input supports sample rates up to 768 kHz PCM and DSD 512. For additional convenience and flexibility, the UDP-205 can convert digital signals from cable and satellite boxes, televisions, video game consoles and other digital transports with coaxial and optical digital outputs to analog. By bypassing the low fidelity, poor quality DAC of traditional computer soundcards, the UDP-205 turns any computer into a high performing multi-media source by utilizing the ES9038PRO DAC.

    I'm pleased to say that installing philippe_44's 3rd party plugin "squeeze2upnp" appears to have solved my problem.

    After "bumbling" my way through the settings instructions for a few hours the Oppo now shows up as a player in both LMS and the SBT. I've used an optical cable between the SBT and the Opp.

    Last night I was able to use my Orange Squeeze smartphone app to play music files through the Oppo's analogue settings thus taking advantage of its AKM DAC. The embedded album art in the files also came up on my TV screen whilst the song was playing.

    Superb sound!
