The Black Hole......

[Hans Polak]

96 is OK. Are you going to do listening test at an even higher sampling rate? How do files compare at 192KHz ?
Thats the rate I suggest is best (or higher).... the point of diminishing returns.

No problem at all.
Suggest a nice track from an album, and I’ll be your man.

I wasn't sure if the 24/96 gets through without being downsampled, I guess it does.

It should do. But often hard to check.. There are often some points of concern, esp if a windows machine is in the way. In your case with Chromecast double jeapardy! I just fitted some new Comply tips to my headphones to listen at work to the samples and realised I can't confirm bit exact without ASIO4All and having tried that before it stops other things I need working. Phooey.

Where does 40KHz come from? That which JC and I and others have used as a min for decades ---->from listening tests....the linear phase deviation has to be less than 5 degrees. from 20 to 20KHz which means the freq response must be from no less than just under 1Hz to 35 KHz. (6db/oct). So we just say 40Khz, -3dB.

Thanks Bill, the chain seems capable, I can't check it though with my chromebook. The alternative would be the headphone output and I think it's safe to assume that would be compromised.

I cant't really hear any big differencies, but in my opinion:

A = 1
B = 2
C = 3

Why do you feel this should be important. Your speakers have orders of magnitude more phase shift.

Edit: where in the Handbook did you find this? Will look it up.

Yeah, why is it important to have amps with better than 0.1% distortion while speakers have orders of magnitude more? 😀

Geeez what crazy questions. Detecting a change is what we do when we compare A to B.

Speaking of which, can you detect a change between Hans' A,B and C sound files?

 

[mountainman bob]

Dont worry, I only have some funky in ear things and an All-in-One desk top computer. Hardly my best quality system. Maybe medium rez? We both agree on A being worse.
I might say C and then B.

See above

 

[scottjoplin]

Thanks, he was number 2 or 3 then, I missed that, which answers his previous question about whether I read all his posts.....
I don't get why the difference if everything is "medium res"?

 

[indra1]

Geeez what crazy questions...

I think it is a good idea to have an amp trading slightly higher distortion for reduced speaker distortion like your 0.22r in series with the speaker trick. Why did you categorize my question as crazy?

Ah Review and Measurements of Chromecast Audio Digital Output | Audio Science Review (ASR) Forum suggests chromecast is non ideal, but better if you have roon

Thanks Bill. That isn't what I have, apparently it's been discontinued. I have the one with HDMI output running through one of these Audio De-Embedder with 3D Support the coax output feeding a DCX2496

Matt, try concentrating on the leading edge of the piano strikes, cymbal decay, and bass accuracy.

It is the detectable change... delta ... which does not matter if freq response is flat or distortion is not zero. To a degree.

yes, a slight reduction of high OL neg fb voltage amp will barely be noticed compared to a 50% drop or more in speaker distortion.

Handbook for Analog Sound Engineers. Nowadays, we can do filters that start at 22kHz and has almost 0 phase deviation at that frequency.

But, obviously, the analog will output *something at 34Khz whereas the digital will be more or less silent at that frequency.

"From the data acquired, it is safe to claim that this experiment will stand
as a foundation for future experiments further investigating the effects of the data that exists above
20 kHz."

10 years in the future we are still waiting?

Well, from what i have measured, there is considerable HF after the filter still. Needs more effort .
