Just compared dan’s test tracks (subjectively)
Listened to track one....took notes....compared track two......noted differences.
Track 1. / Track2.
Compressed / Open
Smeared. / Focused, better separation
Shallow stage. /. Deeper stage
No dynamics. /. Dynamic
Unnatural effects. /. Natural effects
Lack of detail. /. Much more detail
Lack of leading edge transients /. Good leading edge, sharper detail with better decay

Don’t know if anyone cares but track two was a much better version to listen to.....how does this equate to the measurements Scott w took?

Hi Bob and Johnego (and everybody else), here are the CD quality Test Dept files - 00 - Two Flames Burn - ORIG.wav 01 - Two Flames Burn - GC.wav You should find the same kinds of changes, only better.

Cheers, Dan.

Dan.

Ok......just did the second set of the cd quality files, notes as follows

Track 00. /. Track 01
Dynamic. /. Less dynamic, flat
Engaging. /. Not engaging
More depth, 3D /. Less depth,2d
Realistic. /. Dull,hazy,veiled
Raw. /. More refined, perhaps a little more focused
General assessment. Track 00 is much better

Track 01 (second track) is more like the first (track 1) unadulterated you tube track.
Track 00 is more like the second (track 2)of the you tube but better all around.
 
For me music is the passion, DIY audio is the hobby*. I was being serious though. I have never listened to any system that made we want to 'toe tap' more than any other. Maybe I am just sensitive to different aspects of reproduction, which is not a contentious point.

*I would sell the main system if it meant I could keep the music to play on whatever was around.

Just as I read this post this song came on from my playlist and my foot stared tapping uncontrollably! 😀

24-bit file vs. 16-bit undithered file. Can't you make it technically correct???
Pavel (or anybody), I am starting with 16 bit file that needs to be converted to 24bit, I asked and I got the answers as above, but no detail on what to do and how to do it, and then Mark4 stated that I am converting correctly..

Are you saying that I need to add dithering/noise/information to the 16bit file when upscaling to 24bit ?.
If so please advise me on how to do so in order to ensure correct experiment.

Thanks, Dan.

I think, I've mentioned the quite large intersubject differences literally numerous times in the past, which are important in case of the lossy reproduction we are talking about (usually; and lossy in comparison to the real thing), so of course, but albeit that, it would be much easier to explain (and maybe agree) such a term when sharing listening impressions.


*I would sell the main system if it meant I could keep the music to play on whatever was around.

If that means, it is better to have any kind of music reproduction instead of having none, I strongly agree.
But, a real good reproduction conveys surely a lot better of that what the composer/interpreter wanted to express.

People are different, but for me its a lot of work to not let destroy all the joy of listening to Pärt's Alina when reproduced about internal speakers of laptops or mobile phones and actually it is better to listen to my memorized incarnation then to that kind of reproduction.
 
With respect to Uncle Bunt, it was not my initial intent but I realized that it was a mono file. This was easy to verify with the downloaded file L-R was identically zero. There appears to be a 0.01% gain imbalance in the recorder so each successive copy had a slightly worse null and of course some added noise from the A/D and DAC.

I was able to null all 3 to better than -90dB residual so all these files essentially remain mono. There is no depth or width information here at all.

I heard nothing of note on any of them, if someone can perceive the slight growth in noise floor this far below the noise floor of the recording good for you.

Again sighted listening with an easy cheat for those that "can't" be wrong.

You can continue these tests but as promised I will try not to feed it.

Agreed

I'd never sell my Etymotic ER4s! They do a good enough job for the music when total immersion is the only option (like Alina of which I have numerous versions).

Have you done something to prevent any impact from your certainly present bias?
 
It has a scientific meaning, that's fine, but it's also two words, that everyone understands, put together in a context that people can also understand, is that really so wrong?

No, as long as everyone knows what meaning you are using, if the formal definition varies from the other.... Hence better to stick to well defined agreed meaning terms... if possible!

Hey, Dan - how about some photos of the setups - and showing us what gooped stuff looks like? That would be interesting!

You are no doubt correct, but.....I wonder how many people were in any doubt before Mark came along and accused me of....erm.....FUD 😉

New interpretations that involve soul,funk,blues,jazz fusion get the blood moving for me.
Not new, but check out Ornette Coleman's Of Human Feelings
 
hmm, to me 'toe tapping' is a function of the music.

Yes, I have danced all my life. Finger snapping, hands a clapping, toe tapping, bobbing and weaving, hips a swaying, arms waving, it’s all dancing to me. No matter how good the playback is, it’s the music and only the music, that counts when out on the dance floor.

I don’t believe in PRAT, it’s marketing speak for those who cannot dance, but would like to. Rhythm is all about timing. Just listen to James Brown, he would drill his backing band in rehearsal until they played funk like robots, and then when out playing on stage he could get an audience up on their dancing feet within seconds.

You fellers asked what music I enjoy,

I can imagine. Sorry if my response above was a bit harsh; in hindsight, it doesn't sound as jokingly as intended.....

Did somebody say Robots?

In the vernacular it means apprentice and the one calling you that is the master.
Thanks for explaining that. I suspected it meant something like 'he who still has lots to learn'. In Dan's world that is true; however, in my world (also occupied by most other people on here, and every item of audio equipment ever made by anybody) the tables are turned and it is Dan who is the grasshopper.

What if someone said, from now on I am going to use the term resistance when I mean harmonic distortion, because the first term is only one simple word?

I think we can probably all agree that would be a bad idea. So, don't know why it should be okay when it is some other technical term that is misused.
