You sell yourself short. Thanks for taking the time to write this up.

I've heard this as well but I only have it in a lossy format (PM from you know who).

Right.

 

So why is it so difficult for some people here to accept that such D/A inaccuracies are audible? Without such an acceptance, we'll never get to the point where audible D/A inaccuracies can be understood and overcome.

 

Mani.

 

This would be a great response if we were discussing D/A conversion but we aren't.  

 

We're taking about Alex's theory that noise can somehow be embedded in a digital file.

Sure. It seems to me that it's the most likely mechanism responsible for audible differences at the point of D-to-A conversion too.

 

 

I think many people would agree with you on that.

I strongly believe that the rules of hearsay evidence should apply to this thread.

You keep saying this like it's a bad thing...

 

What Is the Difference Between Skepticism and Denial?

People sometimes confuse skepticism with denial. Skepticism allows scientists to reach logical conclusions supported by evidence that has been examined and confirmed by others in the same field, even when that evidence does not confirm absolute certainty. By contrast, denial is the act of clinging to an idea or belief despite the presence of overwhelming evidence to the contrary.

 

In order to remain objective, scientists must remain skeptical. In order for scientific knowledge to be advanced, that knowledge must be open to revision. Science works to determine the statistical probability (mathematical likelihood) of a claim's accuracy, not its certainty. Similarly, in a court of law, juries are asked to accept a level of proof that is beyond a reasonable doubt — not absolute certainty — when deciding to convict a defendant.

I have also said that you can REGENERATE the files to very close to that of the original.

 I use an Uptone USB Regen powered by a very low noise battery derived PSU to do this.

 

Alex, 

So here is my understanding of your claims.

 

1. Ripped data from a CD drive connected to a good PSU sounds better different than ripped data connected to a crappy power supply, even if the files are bit identical.

 

2. Sending a file over the Internet causes a decrease in sound quality, even if the files at both ends are bit identical.

 

3. Zipping the files into an archive without compression before sending over the Internet allows files to be protected from this degradation.

 

4. Compressing and then uncompressing files causes a decrease in sound quality.

 

5. Files can be restored to "very close" to their original quality using a low noise power supply. 

 

Have I missed anything?

How can he attack someone's credentials when he doesn't even know what they are?

 Several prominent members have confirmed this recently too, one using the videos side by side on his 4K monitor for comparison.

 

 

My recent experience with your "testing" revealed serious issues with your methodology including the fact that your file names make it clear what the "answer" is.

 Garbage.

 Only one of the ADDITIONAL 2 files ,(there were 4 different versions of the same original file)  in this case

 

DELETED LINK

 

  gave any clue as to which file was which, and was given as a reference point ONLY .

 

 

You might want to delete that Dropbox link from your post.

The primary problem with your testing methodology is related to what Eloise told you almost four years ago:

As I see it; the main problem with Martin Collums so called "blind" testing was that it started out with a false assumption ("the files are different") and then tried to ascertain which was the best. He isn't testing IF they are different.

It’s bit suspicious to keep using as proof  someone else’s results that you can’t name, using testing methodology that’s not published, with test samples that you don’t want to share with anyone but those who agree with you before doing the test.

Well I used a Macbook Pro with Retina display.  A gaming laptop with a better than average display, a video projector (and you did send pictures of someone's projector you said showed the effect), and a Dell calibrated UltraSharp desktop monitor (my best quality display).  The eye candy was nice, yes.  None of which matters to others in the end.  

 

As far as I can tell, Alex only accepts positive results.

 

This cherry picking of results is, of course, another serious flaw in his testing methodology.

 It is accepted by many members that even the Mac Mini is capable of markedly improved performance, but based on theoretical grounds you refuse to accept the numerous reports about this in the Uptone forum, and keep insisting  that what you are currently using is more than adequate, even rejecting the validity of using an ISO Regen etc. to further improve USB audio.

 I would expect that a Maci Mini using a John Swenson designed LPS and USB Regens etc. would result in a marked audible and visible improvement over what you are currently using.

This is an Audiophile forum , NOT a sub branch of Hydrogen Audio, .although several of you appear to be trying to make it one.

 

In your vision of what this forum should be, the fine work to uncover the truth about MQA would never have taken place.
