Hi Coris

I have a OPPO BDP-103 which I have upgrade a little.

1) I have change the IEC power inlet to a Furutech NCF IEC power inlet, plus 230V power the cables is also changes to Cobber/Silver cables.
This has improved the sound a little, there is more power on the colors
2) I just ordered a linear power supply, which I expect a lot from.

I did "only" buy a BDP-103 because I use an external Hi-fi DAC, so sound quality out of the analog side does not interest me.
I use the optical output into my DAC.

I was wondering if I could improve the picture quality further by replacing some of the clocks to reference clocks in the BDP-103.

Which clock would you recommend to upgrade if I chase /go after picture quality?
1) The 27MHz for the main processor.
2) The 20MHz for the HDMI Marvel chip.
3) Both.

If you say 3) both could you give a short example on what to expect for each clock upgrade ?

I have added a link to the clock which I already have and intend to use.

NewClassD Neutron Star

Thanks in advance :-)

Anyone interested here in an unmodified, stock OPPO BDP-105? Mine is surplus, make me an offer, you'll have a machine you can mod to your own delight!

Hi Jacob

Both clocks should be replaced. The original ones are only resonators, driving a PLL inside the chips. The overall result of replacing these clocks is an improved picture quality (more fine details, less noise, improved colours and contrast, richer tonal range). Also the linear power supply for main board is a important factor for improvements.
Also for the best picture improvement is investing in the new model 203 (+ new clocks, and linear PSU)...

Hi Coris


Thank you for feedback!


I don't need the analog stage, so I got the idea to disconnect its power and the flat cable to the main board.
This way do I minimize power consumption, heat and unneeded noise in the OPPO.


I could also use the +15V for powering the clocks, they run best at +15V


Do I destroy / disable any of the other function by disconnection the analog stage ?

Hi Coris


I am not going to upgrade my OPPO BDP-103, because I had a accident
I was trying to dismount the plastic clips for the "radiator" on the main processor and then my screwdriver slipped and did cut a lot of copper lanes to the HDMI connectors


Is your LPM for the OPPO BDP-203 commercial or have you only made for your self ?
If the LPM are commercial could you give me a hint where I could buy one in Denmark?


As upset as I am do I like to see the good things is life, so now do I have the opportunity to get an OPPO BDP-203 even I don't have a 4K TV jet I dont want another BDP-103 even I liked the machine a lot
