A possible nasty artifact in the so-called hires version of the file, which I also downloaded from the website where Mooly obtained it, is that the initial sample is not zero - the clip was sliced out of the full track, and not ramped up from silence at the beginning - which means that resampling software will add a peculiar artifact at the start, in attempting to process the data. Audacity was doing this to me, and I was really scratching my head until I realised what was going on ...

No difference detectable thru my 2822 driven makeshift system in the backroom. Soon I shall have 'one' of my Infinity Qb rebuilds done, then I'll set it up solo (Mono), "flat" & drive it with the Carver....that's about as best I can do. The PS on the backroom set-up is so **** noisy!!

I started with Z and went b ackwards.

Then after listening to them, I really didn't like any of them.
They all gave me a head ache.

Initially I liked Z best.

Then ended up thinking Y because I didn't get headache with it.

Somewhere someone put a link to compression and it had
Take Five on it.

That sounded best to me.

If you have a good vinyl version on it, during the quiet parts
you can hear the drummer counting time, you really have to
crank it up to hear it.

On all the digital versions (that I've heard, and modern
vinyl that has been deleted).

I love to play that song on the piano too. Just FYI all the
sheet music is different than what is on the record.

I just listened to X, Y, and Z again. My earphones have a slight rise above 8 khz.

The violin has a more edgy quality to the sound for Y than for X. For Z is edgyness is much greater.

I also just checked out the bit rate my USB DAC was running at. Checking the rate from the command line, it is running at 44.1 kHz, the same rate for each file.

My Deadbeef player reports different sampling rates for each file. It appears that Pulseaudio in Ubuntu is resampling the rates. The DAC is getting the same rate all the time.

I have been meaning to try an audiophile linux distibution that claims to give bit perfect playback. Then the results may be different.

Unfortunately I do not have the time to install and try out Ap-linux for the next couple of months. This thread is encouraging me to do so as soon as I can.

There's no answer to that one 😉

I think what could be an interesting exercise for the future might be to provide some files, not as a listening test, but as more of an analysis.

I don't understand all the ins and outs of this. If you have a file of (say) 16/44.1 or 24/48, is it possible to make that file appear like for example a 24/96 or will the original signature of its origins always be revealed ?

Unless we can make files appear the same and to not have characteristic traits that can be picked up then unsupervised listening tests will always be flawed.

"Real" hires files have random ultrasonic noise in them - they're actually "worse" then CD quality in this area, 😀. It is indeed "pure" noise, no matter what's happening in the music there is a constant ultra high frequency hissing going on, 🙂. Only a very, very tiny part of the above 20kHz has meaningful information in it.

To fake a hires file, lop off this hiss from an arbitrary hires file, and just add it to the CD quality file of your choice - no-one will pick it, 😀 ...

Is 24bit worth it? possibly,

Yes, 24/96+ is worth it. We can also by-pass the CD recording equipment/processing and the CD playback equipment. .... all together, lower average distortion.

Then there is the convenience factor of having all your music available anywhere and everywhere you go. Cant do that with physical CD's. For example on a long overseas flight -- no music or portable files? And, even the portable players are getting better --- the PONO I just listened to is a LOT better than the Apple iPODs of various types. I'll load that up with 64G of 24/96+ files and go.

130dB is just a distant goalpost, for some day, 🙂. In real terms I would peak at 100dB, perhaps 110 on a more ambitious setup - but it's the quality of those SPLs that counts ... most systems are straining when at those levels, and it's too disturbing to listen to ...

This one could be interesting. I hope so anyway.

There has been much discussion in other threads on whether true high resolution formats are worthwhile. Opinions seem to be going all ways on this.

Myself, well I'll be honest and say its an area I've never looked into. I use CD and am happy with the results.

So what have we got here ? Well there are three files, all of which are short at around 7 to 8 mb and each plays for around 25 seconds. Although all are of the same piece they start and end and fade in and fade out at slightly differing points. So all will show as a slightly different file size. In other words you 'gotta listen (how many times have I said that before... are those the Cray computers I hear firing up now 😀).

Anyhow, there should be a definite hierarchy to these three files in terms of quality and resolution.

See what you think and, and the question is... try and pick out which you think is the file of highest resolution. As ever, there is a poll with three choices. Just vote for which you think is the highest quality file. No more clues will be given other than to say that none of these files are from CD.

FILE X

FILE Y

FILE Z

Did you shut down the test. I cant open it to play.
