HDMI isilencer

When Oppo sold the 205 4k universal player, they advertised that its HDMI output was lower jitter (than other players with HDMI out on the market). I betcha didn't know that?

This is with their HDMI (audio only) output and they stated on their Website (Still may be there. I haven’t looked), one may or may not hear a difference. I never did when comparing the two outputs into my AVR.

The data rate on HDMI is way beyond the sample rate of the DACs etc. in the receiving equipment. So the serial data on the HDMI link will be read into parallel memory and processed in a DSP at a different clock rate (no jitter will affect this processing). Consequently, the clock rate seen by the output DAC is different to that on HDMI data.

Jitter issues are another of the fallacies peddled by a lot of 'audiophile' companies to make money, all it does at sample rate is add a bit of noise way down in level so out of hearing range or so low it is masked by the audio signal.

Yeah, see that's what I was thinking with my original comment above.
I think you and JediJoker need to hash this out!

Of course. Whether one hears any difference may depend upon their system, electronics, room, room treatments, and their own ears and brain/perception. And any placebo effect whether pro or con! But Oppo engineers felt that they objectively designed a cleaner HDMI output that might translate into better audio at least for some!
