He knows fair bit about objective video evaluation but sadly, nothing about audio and got taken. He is impressed with SMD rework of components which technicians know how to do. He doesn't so he thinks it is magic. He is unfamiliar with instrumentation being used so gets confused there too. See this evidence of noise reduction:

I have circled the important bit in the spectrum display. The *starting* frequency is 27.55 megahertz. NOT kilohertz but 1000 times higher at megahertz. The ending spectrum is 54.9 megahertz. It is not hard to reduce these high frequency noise levels. Manufacturers only do so much until they pass compliance tests. Of course no way such noise is audible.
The plot thickens when you read the comments and specific point by "cinemike" himself on how the audio tests were done:

Yes, he is using a digital audio and video connection out of the Oppo. So no changes to the DACs or anything. The DAC is actually in the Marantz AV processor which is unchanged in the comparison.
He is simply being biased in listening in more carefully when he is told the modded player is working and as a result he "hears" more detail. That is very common but non-intuitive to a lay person.
It is a totally wasted mod if it does not come with any objective audio measurements.
The HDMI connections are used here for digital picture and audio improvements.
Vincent experienced a more satisfying visual experience.
Oppo doesn't make those players anymore, no replacements either.
So the best way to improve them is to modify them, or buy a new player like the Panasonic DP-UB9000 4K BR player or the Pioneer BDP-LX500 Universal 4K Blu-ray player, and save over $5,000-6,000 US dollars.
Or, stick with them as they are...203 and 205.
Or, Mike is not the only mod guy in the world...there are many more, from all over.
Coris is another one ...
