No significant results, as anyone with some basic knowledge of digital systems and perceptual testing was expecting.

Follow-up tests with participant #2 did not produce any significant results.

What a fantastic positve and constructive reaction for someone with “some basic knowledge of digital systems”

Update of the pre- and post-echo experiment, see the attachment.
Excellent work, as usual, Marcel.

We wait to be enlightened by such basic knowledge. Exactly, how you would have designed and conducted the experiment?
For the record, I'm fine with Bill drawing different conclusions than I did, in fact I called my own conclusion "somewhat speculative", but his summary in post #1521 is inaccurate as the first test did result in one significant result.

PM number 4 arrived
Just received the fourth PM, so we are getting somewhere.
Two more to go and I will disclose the results.

Nearly There!
We're nearly there, guys
!
Just two more reports sent to Hans, and then we can find out what was, or was not, heard via high-performance 176.4 upsampling

Where are all the self-acclaimed golden ears?
And all the deniers? You can do a blind test easily by yourself. If you can't hear anything that's easy to report as well...

I am not a golden ear, but I have a very revealing reproduction system. Unfortunately my best dac is down at the moment for upgrades, and I'm busy working on other projects currently at a higher priority. Otherwise, I would be happy to listen.
That said, I haven't noticed much difference in sound when I upsample from 44kHz to 192 kHz in hardware. The dac sounds only slightly better with CD upsampled 192kHz.The big improvement with some dacs is from conversion from PCM to DSD256 (or higher). Of course it matters how well the conversion is done.

I am not a golden ear,

"I know I can hear smaller changes than .5dB."
"I am very sensitive to distortion"
but I have a very revealing reproduction system.
Better / improvement in sound reproduction system is the level of audible transparency. Without the reference material to compare side by side, it's not a meaningful evaluation. Just an impression, which is fine for your own consumption but it unfortunately serves no function for others on their side of computer screen.The dac sounds only slightly better with CD upsampled 192kHz.The big improvement with some dacs is from conversion from PCM to DSD256 (or higher).
That's quite contrary to what you've been posting.

And you sound like a broken record….

It's always the same - either there is an excuse like in @Markw4's case - which I think is totally invalid/irrelevant anyways. I managed to produce the single relevant result (and a "half relevant" one in the retest) with very mediocre DAC, amp and speakers in the echo listening test. So you could at least whip out your "second best DAC" and headphones...
And @Evenharmonics: Same on the opposite side. Just babbling, no action.
Not sorry for getting personal. 😱😎

I had to reorganize my dropbox, so all previous links are lost.
That's why I give new links for the resp. files.

You guys sound frustrated that more people are not joining in.
@Hans, There is another old saying: you can catch more flies with honey than with vinegar.
