Bill, we have all heard systems and audio devices that sound bad/irritating and with any program or at any SPL.
I'm saying this is not entirely due to the standard measured distortions and I reasonably suspect that this can at least partly due to PIM generated by LF excess noise in passive and active circuit components.
My filters change the nature of this system intrinsic excess noise, as do ferrite filters.
Part of the mechanism may be due to 'simple' HF filtering/exclusion as per ferrite filters and consequent audible secondary effects.
This however does not explain the change in the nature of low level underlying static and dynamic noise signature.
Ferrite signature...relatively loud/nasty/annoying.....Bybee signature...very quiet/slightly nasty/boring, Mad Scientist Black Discus signature...nicely quiet/pleasant/Muzak boring, my filters....very quiet/exactly neutral/fun and exciting.
Like I said I am waiting on getting hold of particular ingredients that are confirmed to cause loud/nasty/disturbing signature and make real time listening sound signature 'drive you out of the room' bad.
This signature should also transfer to digital files based on present and prior experience.
When I am ready I will present at least three files for comparisons.

The sound of a system is determined by the electrical waveform passed to the transducers. The electrical waveform is determined by the source, in this case a DAC. For a given DAC the waveform is determined by the sequence of numbers encoded in a digital stream. When playing a music file the sequence of numbers in the stream is determined by the sequence of bits in the file. Therefore, if you have two files which are bit-for-bit identical, and they produce different sound, then either:
1. The two files are not identical
or
2. The two files do not sound different
or
3. The two files are not being played back correctly.
All of your hand-waving about energy and noise is just... excess noise. I do not believe that you have any such files, though I believe that you may believe that you do. There is also a very good chance that you know very well that you do not, but enjoy the game. You have been making this claim for a very long time but have never provided any evidence, and I feel like if you really believed this stuff you would have put up by now.
Now if you claimed that you passed an analogue signal through your filters and got output that differed from the input, then I would believe you, though that would not be a very remarkable claim. But this notion that you passed a digital stream through your filer and produced an output stream that did not differ numerically from the input but sounded different is just malarkey. It's like saying you copied a word processor file via your modified cable, all the letters and words were the same but the text, when read, had a nicer "feel".

Yes. Things aren't looking too good for Dan right now. Making commitments then delivering distractions, excuses, diversions, and or delays is very hard on perceived credibility.

Hi Soongsc.
Yes, if a few here were to speak to me directly they would likely gain a very different understanding to that which I can only briefly put into words here.
Their attitude would likely change from one of derision, to one of true wonderment....and the realisation that what I am discussing has been right under their noses all their lives.
'Education' can also be a form of 'hypnosis' by means of propagation of mistruths by 'authorities' on the subject at hand.
For example, I believed my lecturer when I asked in lectures if cables/wires are/can be directional.
His answer was an assertive no, no doubt merely relaying what he had been told.
I have since found this assertion to be untrue, and find that wires/cables can indeed have direction dependent characteristic behaviours....and so it goes.
Dan.
He was right, you and other believers in cable directivity are WRONG, it would have been noticed in main stream electronics by now. If you have proof show or stop spreading untruths...
You mean he still had credibility with you after all these years?? Man, you guys are sooo gullible!

Dear All,
Snake oïl audio belongs to the realm of psycho-acoustics.
That is, you hear what you want to hear.
Especially when you have spent big $$$$$
You convince yourself that your system now sounds better, or that the new additions (cables, wooden lenses, files...) make an audible difference...
We need a new breed of psychiatrists to heal those who hear things. 😀

Your lecturer was right. It is unfortunate that he didn't teach you enough physics so you would know why he was right. You may be confusing education with training; the whole point of education is that you go beyond your teachers - but first you have to catch up with your teachers. Lagging behind is not a more sophisticated form of being ahead.
