Sound Quality Vs. Measurements

[johnego]

Next time you go to a cash machine and type in 100 but only 65 comes out see how you feel about accuracy then.

We're engineers. Oh, snake oil peddlers again?

 

[N101N]

Here is an even more tricky question for nontrolls that Newton forgot to explain: how in the hell can forces be attractive?

 

[TNT]

You mean gravity? Please do tell.

[N101N]

The Higgs boson has the extraordinary ability to exert a force on itself. Incredible but true.

 

[TNT]

So you brought the discussion down to Plank length level - now please tie it all back together so it makes sense for everyone! Or are you just showing off your newly acquired physics knowledge.

anatech,
that`s not much of an explanation. Just because you don't know something doesn't mean it's not correct.

Hahaha!
First he bashes Hamilton, then he comes back at you ! He may be a hateful Heisenberg scholar, somehow belonging of an exotic offspring of Schrödinger, or - even better - of exotic Dirac stuff. Neh, I am joking.

No harm done so far (hopefully), so let's give credit to a ... probably 14-21 yo reader.
He will come to more sense some day, of course only when and if he grabs that book seriously.
Till' then, it's amusing to read his innocent impetuosity.


[Of course things and our attitude shall change if he is over 25. Don't you think so?]

 

[N101N]

TNT,
Are you angry with me?
Everything happens in the realm of quantum orthodoxy.
But no, that`s the mathematical explanation of gravity. The physical explanation is much more elaborate, no wonder Newton could not figure it out.

Read my lips: I do not believe that !
Prove it. Or send me to a paper which explains so. Now I am curious.

Not necessary young. A troll of the same magnitude, a striking resemblance, was one KBK character, middle age, physicist by trade, which was peddling here mercury filled cables providing, of course, a more liquid sound.

My friend, I am sure that you confuse badly the physical notions. On the positive side, I am not sure about your orthodoxy teaching. Nothing wrong to mix them, but: " The Lounge - A place to talk about almost anything but politics and religion ". So, please refrain yourself.



We can still talk about physics... when you will learn it better

 

[Evenharmonics]

The best amplifiers in terms of SQ tend to be expensive.

When you say sound quality (SQ), it would mean audible sound. In that sense, what you stated is a lie. Double blind listening test revealed that very expensive amp like Mark Levinson and much cheaper amp (< 10% price) were indiscernible by ears.

Personally, I believe that some people can hear certain details of sound smaller than published 'limits of audibility' might suggest.

Whatever helps your business agenda.

 

[Ionmw]

... how ... can forces be attractive?

Of all your texts, this is probably the only one where I will ask you: what do you mean? Please do clarify better your question and opinion.

Chord says they attenuate audio band noise down to -300dB in the digital domain because listening tests show it makes a difference for some people.

Aaaaand... we have a new audibility frontier, -300dB of audio band noise. One more step and some could claim hearing the gravitational waves, ears only. No, this is not in jest, LIGO is essentially a low noise, ~400dB gain parametric amplifier.

 

[N101N]

Read my lips: I do not believe that !

Why not? Anything is metaphysically possible, logically conceivable and semantically permissible.

I have some troubles to imagine him any older than 25...
But you can be right. Trolls are nasty stuff, in general.

 

[syn08]

When I was 25 I was more interested in chasing girls, rather than trolling a public forum with pataphysics. But then today this must be the new cool, what do I know?

 

[Ionmw]

Why not? Anything is metaphysically possible, logically conceivable and semantically permissible.

I have reasons, of course! Better than yours.
From Gödel we know that any model (=theory=science) can exist only in a finite set. So, what are we talking here?

 

[N101N]

Now you are ignoring the theological infinity element.

A 32-bit word size can matter in a dac. Its how they get the internal volume control to be high performance. ....... Chord says they attenuate audio band noise down to -300dB in the digital domain because listening tests show it makes a difference for some people. Of course, they have no idea why. One can choose to believe their story on not. I personally have never tried that experiment, so I withhold forming a belief about it.

An electronic VHF signal, amplified to 1 KW, put into a large antenna pointed to
the moon, travelling through the atmoshpere and then 380000 Km to the moon,
being scattered into all directions by its dusty surface, travelling back 380000 Km
to earth and being received again by a large antenna is just barely recognizable.
That is a total propagation loss of about 250 dB.

Claiming that some people can hear even 50 dB more of propagation loss is
not funny. It is seriously insulting, like someone selling $$$ tickets for a party
with Elvis, Santa and Ulysses.

Simply disgusting.
