The first mile: What power stations are best for audio?

[goldsdad]

Also, let's not forget that sometimes these identical claims can sound different, depending upon the font size.

 

And depending on the power supply of the poster's computer.

So now you are disputing the reports from many members who have retro fitted UpTone JS2 PSUs to their Mac Minis too ?

Aahhh ... you are missing Bill's joke -- If one is blinded then can't read the claim on the website forum ... unless your computer does text to voice in which case font might affect sound -- we aren't requiring you to be Tommy

[wgscott]

Just, for the love of god (who is dead), don't post with Comic Sans!

I see very little that is funny, in any posts by the Ill Tempered Audiophool, as I don't pay too much attention to his ranting.

In fact, quite a few members would take offence to a comment about God in a recent post by him.

The same ones who are offended by Latin?

No, I was poking fun at your claim that bit-identical rips of a CD sound different as a result of changes to the power supply of the optical drive that has been used to rip the CD.

Poke fun all you like, but I am able to prove what I say via both the MC Blind tests, the other related HFC forum threads, and direct demonstration, as I also did for a highly sceptical Sydney EE through his own system.

Perhaps some Mac Mini owners who have retrofitted a JS2 PSU could try comparing earlier ripped .aiff files with newly ripped ones after the JS2 was fitted ?

Did you read what Alfe has to say in the Tutorial thread he posted ?

 

BTW,

The files used by M.C. in the 6 Blind tests were ripped by 2 different Optical devices. The LG BR writer was powered via a JLH PSU add-on , and the other was a cheap portable USB powered DVD Rom.

You should get in touch with James Randi and collect your million dollar award.

The Randi people have been shown in the past: (a) to avoid paying with flimsy excuses when shown to be wrong; b) to not know how to properly set up a DBT to test claims they want to debunk.

 

They are at least as much of a joke as the audiophiles they make fun of.

[4est]

+1 I cannot believe anyone would think them credible.

You can't believe anyone would be sceptical of paranormal phenomena? Wow.

No, obviously that's fine. The problem is that they are a bunch of pseudo scientists who can't even implement the standards they claim to believe in. Not knowing how to setup a proper DBT makes them not credible, if you want an example.

 

Again, in the guise of objectivity, you let your own biases influence your opinions. Just because the organization purports to be about debunking paranormal phenomena, that doesn't make it any more serious or reputable than many of the people or organizations they are sceptical of.

Reputable or not, they are offering a million-dollar reward, and hearing differences between identical files would certainly be a qualifying feat.

They are a sham, it is a publicity stunt and they will never pay out regardless of outcome.

I don't remember reading a tutorial thread by Alfe, so I guess not.

I think that Alex is referring to this thread:

 

http://www.computeraudiophile.com/f7-disk-storage-music-library-storage/optical-drive-25421/

 

It presents a lot of good information explaining why CDs may sound different when played back but doesn't provide any answers to explain what Alex is hearing (two bit-identical rips sounding different).

 

In fact, I asked the author (Alfe) if the phenomena he discussed would explain bit-identical rips sounding different and received the following response:

 

Tom,

 

Just for clarification I never said and will never say that identical bits sound different, I just tried to find out why Alex and others can hear a difference.

I could see only two possibilities the data are spread on different packets that may affect the bit rate(BER) or it make the jitter higher during the reading process or the non uniformity of the checksum is the culprit.

I had to start first with the behaviour of the optical drive to try to explain what happening first and if the two possibilities can be covered.

So please let's forget about the bits are bits war, and let's continue to try to find what is behind the mathematical assumptions.

And anyhow if at the end you are not convinced by my demonstration I'm sure that in any case you are learning stuff about the optical drive:)

You keep insisting that they are just my perceptions. There are now quite a few C.A. members who have also heard them, some going back as far as >5 years ago in a thread where even the designer of the very highly regarded Phasure NOS DAC, and XXHE software also reported hearing the differences from my uploaded .wav files.

[jabbr]

Who else has independently replicated your results over the past 5+ years?

What do you mean "keep insisting"? I have never even suggested that you are alone in perceiving the differences you hear.

[sandyk]

The only one that I am aware of who has done this independently would be Silverlight (Geoff) from NYC.

Geoff even claimed to hear the differences between different OS's and even posted a report about tracks created using Demagnetising, Ion treatment of CDs and CD cleaning. He uploaded the tracks and Jeff from Brisbane Au. and myself were also involved. We all chose the track created by simply washing the CD as sounding better. I have been unable to locate these posts again.

Few members would have the time available to get involved in this area. As I am retired I have plenty of time to indulge in this and DIYing audio gear. The incentive for me is to keep enjoying music for longer as age causes further hearing degradation.

[jabbr]

See for me and on my system, the OS, computer, brand of drive and power supply hasn't had an audible effect on CDs that are ripped, stored to my NAS and played back.

 

This effect might be something unique to your specific system and way of doing things but does not appear to generalize to my system nor way of doing things.

[jabbr]

To clarify the above statement, that is for the ripping phase. The playback phase is another story and I do believe in minimizing noise in every reasonable way.

No, it isn't unique to my particular system, and has been duplicated by quite a few other DIY members of another forum.
