Agreed, if you use a AES RGB cable, you’ll probably be able to see a difference with the upgraded RGB. In Modzilla’s vid, he does a comparison between the CBOX output and the OMVS, the video is washed out and the audio is not attenuated.I haven't done it, but replacing the AV should be really easy. The Jamma harness connects to a PCB that routes the signals to the back and it runs through a couple of smaller soldered in PCBs that handle the outputs. I haven't looked at it in depth but I believe one of the PCBs is probably the buffer for the RGB signal and the other is a RGB to component/composite transcoder.
I just ordered some MVS RGB PCBs from OSHpark for another project, if I'm not too lazy I may try to swap the RGB board out with one of the spares. I doubt I'll see much difference in video quality though since the deficiencies in the unit stem from the component transcoder and not the RGB signal.
