“X-rays have much shorter wavelengths than visible light, which makes it possible to probe structures much smaller than can be seen using a normal microscope. This property is used in X-ray microscopy to acquire high resolution images, and also in X-ray crystallography to determine the positions of atoms in crystals.

X-rays interact with matter in three main ways, through photoabsorption, Compton scattering, and Rayleigh scattering. The strength of these interactions depends on the energy of the X-rays and the elemental composition of the material, but not much on chemical properties, since the X-ray photon energy is much higher than chemical binding energies. Photoabsorption or photoelectric absorption is the dominant interaction mechanism in the soft X-ray regime and for the lower hard X-ray energies. At higher energies, Compton scattering dominates.

The probability of a photoelectric absorption per unit mass is approximately proportional to Z3/E3, where Z is the atomic number and E is the energy of the incident photon.[64] This rule is not valid close to inner shell electron binding energies where there are abrupt changes in interaction probability, so called absorption edges. However, the general trend of high absorption coefficients and thus short penetration depths for low photon energies and high atomic numbers is very strong. For soft tissue, photoabsorption dominates up to about 26 keV photon energy where Compton scattering takes over. For higher atomic number substances this limit is higher. The high amount of calcium (Z=20) in bones together with their high density is what makes them show up so clearly on medical radiographs.”

I.e., portable CD player/headphone system, you can reduce mass a lot more AND eliminate even more things that produce distortion and noise -

"Interconnects, speaker cables, digital cable, big power supplies."

if you really want to get into discussions of how electronic waves propagate in circuits, you need to look into the work of Dr. Ivan Ndip at Fraunhofer IZM in Berlin. fascinating stuff. those waves don’t confine themselves to the wires or circuit traces on a board or wiring harness.

You guys would serve yourselves well by seeing what listeners are actually "doing".

LOL, Hemi you’ll be OK. Again thank you members who are Tunees and thank you Agon for this forum.

Hi Geoff, maybe the members who keep in contact with me are wrong, but I don’t think so, I see the same thing they do.

Here’s the good news folks, the industry and hobby are getting their act together by selling off their massive systems and going Low Mass. If that’s trolling man am I guilty as charged and loving it. You guys would serve yourselves well by seeing what listeners are actually "doing". In the meantime I hope you don’t mind folks enjoying the heck out of their systems after being stuck in the box for so many years.

PS: I believe this is still about listening to music :)

it’s very simple

"everything affects everything else" and the only way you are going to find out is "do". All the rest is really want-a-bee talk or internet trolling.

This year I have seen many HEA audiophiles dump their gear and go low mass and tunable (thanks). Some of these folks are members here who have told me "never going back". So to these members some of you guys look pretty silly :)

Hi Tunees, thanks for your emails and PMs! Is the activity here shrinking by big numbers or have I missed something? Stereophile died because of trolling, is the same happening here?

From a musical point of view, it is still interesting to describe what the EVO does in 432 fashion.In fact, you are transposing, because you play the music in a different key.The A on the keyboard is not quite a Gis, but something in between.The music is thus not fully transposed to the scale of Gis.That sounds (in the ears of the undersigned) light alienating and sometimes here and there dissonant, especially if you have the voices of artists in your head.So a piece of music gets a different atmosphere.A curious sensation is listening to piano or guitar in 432 mode.It experiences as listening to an instrument that is not properly tuned.

“This frequency of 440 Hz is called the standard "Concert Pitch" and has been the practice everywhere since about 1939. It was officially adopted by the global ISO Standard in about 1956. Just about all the music you hear is adjusted to this specific pitch. But this was not always the case.

The story told on the web claims that most ancient instruments in human history were tuned to a different pitch. The one most preferred was 432 Hz. It is claimed that even the oldest flutes, dating back to the Neanderthals (45,000 BCE) were tuned to 432, as were the lyres in ancient Greece and the wind instruments discovered in Egyptian tombs.

An interesting story claims that the lyres of the temples of Greece were an integral part of the ceremonies worshiping Isis and other so-called mystery schools. Cult members were aroused to states of ecstasy by the sounds of this 432 Hz tuned music which, in the case of the Eleusinian Mysteries, made them filled with compassion and altruism. For this reason, according to the story, the war-like state of Sparta had all the lyres re-tuned to a higher frequency, thus nulling the anti-war sentiments.

Obviously, the ancient people did not have tuning forks or digital meters and so it is presumed that this frequency of 432 is intuitive, meaning that it somehow sounded right to the human ear. This kind of intuition is supported by the surprise that even the most ancient flutes all have what is called a heptatonic scale of eight notes ("Do, Re, Me, Fa...") such that, if you picked one up back then you could conceivably play Yankee Doodleon it. In fact, in Werner Herzog's film documentary, Cave Of Forgotten Dreams, archaeologist Wulf Hein plays The Star Spangles Banner on a Paleolithic flute made from the radius bone of a vulture.”

"Well, how does one bring it into tune??"

you tune it

"everything affects everything else" mg

you guys should try doing stuff once in a while :)

For those who have already converted to Low Mass Tunable systems, you’re so far ahead of the curve it does make these threads a little odd if not hilarious.

• Virtually no visible light in the IR laser in a CD player.
  
• The detector is a focused assembly. That means that "scattered" light predominantly does not reach the detector as it is off-angle and outside the field of view.
• The interior of the optical receptor is non-reflective to prevent "scattered" light from reaching the photo receptor.
• The receptor has an IR pass filter so that visible light is greatly attenuated.
• The optical assembly is simple and optimized for 780nm, so visible will be less focused.
• The error rates for CD are well known and there is a specific standard for production. The first level errors except for a significantly damaged disk are easily fixed with error correction codes, essentially redundant data.  Unfixable C2 errors on a production CD are typically 0. That means that when you open up that CD, you are going to get perfect data.
• There are many tools available that are very inexpensive that can show C1, C2 and unfixable C2 errors. That means you could easily prove your product has any audible benefit by showing it reduces unfixable C2 errors.
• Jitter measurement is easy. If your product works, you could show how it reduces jitter.
• We have 50X and higher CD readers that manage to work. The 1X of audio .... is exceedingly simple.
• High quality players will reclock the data to eliminate jitter and anything your claimed products will do.
