Osmium in fact, unfortunately fakes were around in audio even back then. Someone took these to a mass spectroscopy lab and there was no osmium.
If a company sells something as Osmium when there is not such in their product, they deserve a prosecution.
it is not specific to audio.
This do not question the fact that osmium is a stronger allow than steel ?
It gives me the idea that the diamond being the hardest material, one could make needles in this material and make a lot of money, what do you think?

Also, I don't understand the obvious hostility towards mr. RNM or Mark from a handful of contributors to this thread. They reports personal experiences -.


If anyone pays someone to take a dump in a DAC which is sold as an upgrade then does a listening test where the ouput of that DAC is put into the ADC on a pro audio power amp and claims the shat in DAC is 'better' with no attempt at measurement or control of bias yes we will point that out.



Better is a word thrown around a lot. 'I prefer' would be more appropriate.



Extraordinary claims require extraordinary evidence after all...
 
IMHO it is scientifically sound to speak about the 14%.

Aural hallucinations mostly consist of hearing voices. A much smaller number or people hear explosions (Exploding Head Syndrome). There are few other known aural hallucination experiences too. None of the foregoing are observed to come and go reliably as a function of A/B listening experiments. Nor for ABX (its problem is false positives).

In some sense all human perception could be considered hallucination since the reality perceived in conscious awareness is a construction of the brain. It is not reality itself, despite it being an overwhelmingly convincing experience.

A lot of made up crap again to support your behaviour and jumping to conclusions I never made....... as told we heard a difference. We both agreed on that. i would not say it is better nor preferred. It might have measured better just due to the extra shielding added to controls etc. To which the modifier did his Full treatment/modifications at NO cost to me. Because I am a nice guy. In FACT, we had a second unmodified unit to do A/B comparison with.

No the crap was in your DAC. And you might want to re-read what you wrote at the time...


Ah no research isn't your forte. You pay a disposable Engineer for that...

I have no idea what the PCB conformal coating is. I am always game to try something new. I had no intention nor did I say I did to do "research' on it.

I believe it was coated with a polymer conformal coating and then an EMI coating over it. Plus other more traditional shielding methods.

In which way could that be an explanation (or even justification?) for any hostility?

Often "better" includes "I prefer" , at least it is my impression, but it must not; but anyway, why don't you think that readers are not able to get the subjective side of such descriptions?
Does it really happen that some new members (totally naive) trip in this thread, and believe anything that is written herein?

It is often not expressed, but for a claim to be regarded as "extraordinary" there should be a lot of contradictionary experimental evidence exist, it is not sufficient that somebody (or even a group) believes it shouldn't be possible.
 
I don't think so, except when dozing off, that level of realism/delusion was only during altered states of consciousness, the point I was trying to make was I have never heard voices, only music.

Something like what you describe is probably possible for lots of people under the conditions given. Perhaps unwise to induce chemically. Thankfully not unassisted/involuntary hallucination in a fully waking state.

This was an 11kv buried cable. Two cheapskate owners who had put steel shoes on had their horses die. BBC Sport - Horse Racing - Newbury horse racing deaths blamed on electrocution

One horse, an accident, and the folks responsible for installing an unprotected cable should be in very great trouble.

The second and subsequent horses should see someone else also in trouble! There were apparently lots of folks around without, pardon the very bad pun, horse-sense.

That's what I'm thinking. But aren't they both due to chemical imbalances in the brain most of the time?

From memory:

In schizophrenia the hallucinations have been largely associated with the high levels or high sensitivity to the neurotransmitter dopamine.

Many people have heard of dopamine as mentioned in connection with little bursts of pleasure associated with reinforcement learning.

Too much of it and or too active a response to it is not necessarily a good thing.

Antipsychotic drugs are believed to work by inhibiting dopamine in the brain.

Normal people who experience a rare episode of aural and or visual hallucination often have it occur during a bout of some non-mental illness.

Rapid onset, short duration, and very rare occurrence are all encouraging signs for it being a not-a-very-worrisome symptom.

The above does not necessarily apply to lucid dream states, or in association with hallucinogenic drug experiences.
