Hello mnyb. Glad to see you guys enjoying Keaton's "kontribution". The man's old but crafty :cool:. Yes, I did test the Onkyo relatively fully back in this post: http://archimago.blogspot.ca/2013/10/measurements-onkyo-tx-nr1009-as-hdmi.html The HDMI jitter actually was fine in comparison to SPDIF coaxial and TosLink! In fact, it was better than coaxial and about equivalent to TosLink using the little CM6631A device for USB-to-SPDIF conversion. This is a bit of a surprise since the asynchronous USB CM6631A is usually quite adequate and relatively low in jitter as in previous measurements. Of course the jitter spectrum isn't as good as with the Transporter or TEAC stereo DAC, but it's quite reasonable and miles better than something like the distortion one sees with NOS DACs when doing the J-Test. Not to mention tube gear which would likely just drown out the signal with noise. I wrote a bit on HDMI and jitter in that post as well...
