I'm slow apparently. What is obvious about why one digital direct connection may sound different from another? If properly functioning and no DSP is being done all should transmit identical information. If it conforms to Redbook standards no timing is different enough to be heard. So what is left to cause sound differences? As the entire purpose of DDC was conforming to standards to ensure bit perfect information it isn't a far step to think the null hypothesis is by far the most likely one. So we've missed what you say is obvious. What is it?The theory of why one DDC may sound different from another seems rather obvious, even though I really struggle to hear any difference. So as a proper scientist I consider neither the hypothesis nor the null hypothesis confirmed. Curious as to why everyone here considers it a dead-ringer that the null hypothesis is scientifically confirmed.

Jitter? Yes, it has to be really extreme. Has there ever been a device with bad enough jitter to be audible? Perhaps, but not many at all.read one post back?

Sinds wanneer woon jij in geenvanbeideland?When a DAC does not have a decent jitter rejection then this is a shortcoming of the DAC.
If you can hear the gear as per #3 wouldn't be a proper blind test, tho....it's blind in more than just plain sight.I'm planning on getting the new TEAC transport when it comes out so I have a dog in the race. (Not that I expect it to sound different from my Audiolab, I just want a transport with good aesthetics and build quality). So I watched the whole video, there are some issues:
1) level matching was done using a microphone
2) Single blind.
3) The players were in the same room as the test subject and DVD/BD players can have very noisy mechanisms. I have a Samsung that sounds like an 18th century threshing machine. I would easily be able to distinguish it blind due to that.
4) no indication of how many passes were performed. To be certain he needs 19/20 or higher. I get the impression he did one pass on each - so could easily be lucky guess
5) He reckons 'soundstage' was the difference at least between the Sony and the Cambridge - alarm bells ring.
6) As an explanation he falls back on the old 'System not resolving enough' and 'Jitter' - more alarm bells - he got the result he expected and wanted, no need to test properly.
Someone needs to do this test properly.
he says he blocked his ears during change-overs but that's open to error, and in the test you can't do that - so any noise from the transport is a dead giveaway.If you can hear the gear as per #3 wouldn't be a proper blind test, tho....it's blind in more than just plain sight.
And then there is the belief that says the digital input of a DAC has to 'work' harder on some transports and they believe that results in analog nasties in the analog output.

But then you can't claim to hear it and can only prove the data output is the same (or not)A better way to test is to find a way to capture the digital out from the three CDTs, and then compare if the digital output was actually bit/byte identical or not…
That would only rule out bitstream errors, not jitter/noise induced over S/PDIF connection.A better way to test is to find a way to capture the digital out from the three CDTs, and then compare if the digital output was actually bit/byte identical or not…

Part-B would be playing back through the single DAC (level matched), as performed in the video, and do a listening test.
