All Linear Power -- Possible?

marce, your use of expertise and electronics knowledge is anti-audiophool

Switching power is the enemy of audio.

 

 

yes, and that is why it is never used for sensitive laboratory research equipment, or for important medical equipment.

 

 

oh wait.... !!!

Did you know that hearing is our fastest sensory input?

 

No.  And I still don't

A better phrase could be that it's our most adaptable sensory input, capable of discerning variations in a massive dynamic range - with built-in, brilliantly engineered AGC, it can withstand staggeringly intense input for tiny periods of time, yet detect below our technical ability to create noise-free environments with ease. Which is part of the reason why it's hard to "trick it",

 

Most playback will fail at one or the other end, or both - not do quiet properly, not do loud properly. Part of the task is to get the setup to do the "extremes" right - this is very achievable; but won't, unless the efforts are made.

 

are you talking about vision?  or smell?

[Ralf11]

why do you think it is used in critical medical equipment?

 

why do you think it is used in highly sensitive research equipment?

 

why are you confused about high grade SMPS and low buck crap?

 

 

[Ralf11]

it might be frutifull to pull apart the very high-end DACs that have 3 different PSs in them - and see which PS is the highest quality one

 

I'd expect that the PS that serves very low level analog signals just after the D>A conversion would be most critical as the signal is smallest there

 

Likewise, I expect the PS in my Audio Research pre-amp is a pretty good one (it was $5k new, and they are known for hand testing and selection of caps, resistors, etc.)

Hey man - audio is special!!

[Ralf11]

oh yes!  remember, science does not apply !!

[Ralf11]

maybe the problem is in the USB cables?

[Ralf11]

I find it hard to believe you are a scientist, as you don't act like one.

You've averaged well over 10 posts a day for nearly 3 years. This can't be healthy.

 

Perhaps give it a break (if not for your sake, for the sake of others)?

 

you'd like to suppress comments - but is that why you couldn't hack it?

[Ralf11]

An audiophile could certainly use the high quality SPMS from a mass spec.  And since we already know of at least one person who has a mass spec. yo would merely need to find the location of their lab, and...

others write the books & papers that describe how the world works

Would you require books to be able to love somebody? Do you need papers to be happy? Do you know you are pure bliss without anything written or even spoken? Sorry for possible OT.

 

 

we were discussing "describe how the world works"

 

that is the role of scientific publications

 

 

[Ralf11]

Sorry.  But I don't see that as an attack at all.  Nor is it personal, as every human on this planet uses life support equipment.
