....you get what you need! I tell my sone this and he just goes:
Well, today was a good day in development. In case some of you are confused about why I am talking about the Sony mods, when this thread is about the Oppo, is that I got so frustrated with the HF noise issue in the Oppo, that I turned to the Sony to see if I could resolve it there first and carry the knowledge back to the Oppo.
Well, today actually bore fruit!
The HF noise is now low enough that it is swamped in the noise floor and I am satisfied with its eradication. A combination of buffering and impedance matching of the clock signal and just the right grounding combination did the trick!
So, I am about 95%-98% pleased with the Sony. I need to tidy up the first article and make sure that all functions work properly and I will be happy!
Now, I will take this knowledge TOMORROW and move onto the Oppo!
Thank you for your support and to all those who are reading this with interest.
