    - Is anyone else waiting for OppoMod's firmware update for the HDMI board to correct the L/R channels output? I'm using the HDMI output into an LKS DAC.


    - Received the silver power cables from China and had some issues trying to insert the short cable (way harder than it should have been). Upon closer inspection, I noticed some of the wires at the connection point had not been properly trimmed. I removed and trimmed the ends of about 5 of the connections. Some photos to help out anyone doing this in the future.


    Inspect from the top down and look for wire ends that block the pin insertion. In this photo, two of the six have excess wire leads.





    Here is a photo of the excess wire end that needs to be trimmed off. I used electronic cutters.

    I installed my I2S HDMI card back in November 2018. The output for both PCM and DSD had the L and R channels swapped for what my LKS DAC was expecting. I contacted OppoMod and was told that they were working on a firmware update to correct the L/R channel output. However, the firmware update cannot be user installed and will require a new I2S HDMI board. I'm still waiting for updates from OppoMod. Some people have had L/R channel issues and some have not. I was hoping that I would get a later revision board without the channel swapping being an issue for my DAC. I'm running with my left and right DAC output cables swapped to correct the channels.

    Ah right...
    Channels sound ok into my Directstream dac, so maybe have a later board...or I’ve swapped the interconnects around without realising!

    I know with some 3rd party i2s output boards, despite sticking with PS Audio specs the channels can be reversed when playing DSD.
    I’d heard Jaehong had addressed this, but hadn’t known he’d looked at a firmware fix over hardware.

    With the silver power cable, suspect you’ve just been unlucky...which is never a nice thing.
    No problems here, but thanks for passing on what you’ve worked out.

    All the stuff has had time to burn in now, and big improvement over how it was initially.
    Wow.

    Roon endpoint, CD player, SACD/DVD audio player, 1080p upscaler, 4K Netflix Dolby Digital/ YouTube/ native 4K disc player...WOW.
    Mods cost more than the player (just!) but took it to a completely different level.

    Put in the research, time and spondoolies to never worry about a disc player again?
    It does all that...and (along with an Nvidia Shield via the Oppo’s HDMI input) everything else network streaming related better than than anything you could possibly need, or I’ve seen in my system.
    Example: Well recorded YouTube live music via the Oppo/Nvidia can be as good quality than my vinyl setup.
    (hint: my record player isn’t an HMV usb record spinner, it’s actually pretty good)

    Marvellous piece of kit, sadly no longer made by Oppo.
    R.I.P.

    Hi Gazjam,

    Thanks for this, and interesting journey.

    I use an Oppo 105D and use it for background when I am working and it is very good, as long as I use Kazoo and NOT the Oppo app. That said it is not as good as my Linn Klimax/EAR868, but them look at the cost disparity. Your mods are tempting!

    The mods have taken the stock Oppo 203 to a different level, and it was no slouch to begin with!
    Lifes too short...go for it!
