In days of yore (circa 2008) - there were massive discussions about Audio Jitter and HDMI
Paul Miller measured Jitter on a bunch of AVR's and this list tells an interesting story:
Denon AVR-3803A
---------------
SPDIF: 560psec
HDMI: 3700psec
Onkyo TX-NR906
---------------
SPDIF: 470psec
HDMI: 3860psec
Pioneer SC-LX81
---------------
SPDIF: 37psec
HDMI: 50psec
Yamaha RX-V3900
---------------
SPDIF: 183psec
HDMI: 7660psec
This was the state of play in 2008/9
Where are we at today?
First thing I notice, is that there are few if any mentions of Jitter measured in ps...
There is an article which states that the J-Test method of determining Jitter is non viable for HDMI
If this is the case - how were the Paul Miller measurements achieved?
And - of more practical import - where are we at today?
Of note: Pioneer's SC-LX81 even then was showing what is possible... all the others had 10x or more Jitter on HDMI compared to SPDIF
Key jitter symptom (often not measured separately): raised noise floor.... aka SINAD
