Micro and macro dynamics...a discussion.

The only difference between dynamics - the difference between loud and soft stuff - and "microdynamics" is magnitude. So why do we need micro or macro when dynamics alone conveys all that's needed? Again, every time I've seen an audiophile type use those terms, they were unable to define what they meant when asked. Such terms only serve to distract us from what really does affect the quality of audio gear. What next, microfrequencies? microdecibels? microbytes?

I think what I posted explained what they mean quite nicely. And the point is you agreed there are differences. So the words dynamic range or just dynamics are general terms to describe the fact that we have differences from the softest of sounds to the loudest of sounds. Because classical music is written to be played at ppp and fff (and all points inbetween), what's wrong with using words that are descriptive of what is going on at those two extremes and between them?
 
a system that is good at rendering volume differences high in magnitude is not necessarily good at rendering volume differences small in magnitude.

Do you have any evidence of that, or even a logical explanation? Not "it makes sense to me," but actual test data or an FFT screen capture? Here's a hint: A full-scale 1 KHz sine wave contains every voltage level between zero and its peak voltage both positive and negative. If there were any condition in the amplifier that caused it to respond differently to large versus small voltages, that would manifest as distortion which is easily measured.

How about the logical explanation that the gear in question has a high enough noise floor that it obscures the dynamics that you would hear at ppp level?
 
-- Anyway, from my perspective no piece of electronic is perfect, no measuring machine is perfect either, we're not even in the expertise of comprehending all regarding acoustics and their various properties, and audio reviewers cannot be perfect when everything ain't perfect and that we are without all the right tools and without full comprehension yet.

So, in audio we can use all the terms (language) we want, including micro & macro dynamics; but they are as good as only what we know so far. ...And there is much more that we simply just don't know. Our researches are limited by our less than perfect tools, plus the tools not yet available. And how it could be when we don't even understand all the ins & outs on sound propagations from various venues, and the acoustics of them venues. ...Plus the music recordings themselves ....
 
I'm confused. Is it that it is nonexistant or "any amp will do it?
 
-- For me it does exist, and some amps are better designed than others at reproducing them (macro and micro dynamics).

But there is much more than just amplification. ...The preamplification, with it's volume control plays an essential role. ...So is the source(s), and not least the loudspeakers, and the wiring, and the room, and the listener, and all their positions within the "sound bubble".
...The encapsulation within a 3D space.

If you don't hear any hiss coming from the speakers when in your seat, then you won't hear any musical information softer than that either. And if you do hear hiss coming from your speakers, something much more important needs to be fixed first!

Ethan, as you always say, a competently designed amplifier....well, the high end is littered with amps not competently designed

I agree that some expensive audio products are incompetent. I don't address those because it's a special category that to me falls outside the realm of "high fidelity."

I 've posted this video before. We can see micro and macro dynamics. It is important to note that stereo equipment does not create these characteristics but thy should b able to handle them. They could be obscured by noise, the cartridges inability to track them,
amplification incapable of handling large voltage swings or to differential small gradations in volume. Driving a difficult speaker load may also be a problem
In the video the problems ar intentional but it serves to illustrate the problem..
 
That's a great video! But it doesn't have anything to do with "micro" or "macro" - just plain old dynamics. Further, a mistracking cartridge, or having inadequate amplifier power, simply adds distortion. No need to invent new terms.

Agreed, although I've always found the ability (or inability) of a system to properly reproduce a myriad of different instrumental impacts (esp at the same time) a very tough test.

Ok it's clear you either don't understand the terms or don't want to. There is no need to mislead others

This kind of statement implies that you are unfamiliar with systems which play both loud and soft but do poorly in between, that is to say with smaller dynamic swings that occur quickly and sometimes frequently. I'm not stating that as well as I would like but I would have to think most people here (except you) know what I'm talking about.

Provide an example, what systems (or components) have you heard that played both loud & soft properly, but couldn't play the stuff in between?

I think it was a combination of source and system. Perhaps you remember the dbx systems that were designed to deal with it. My early solid state systems. It was not until I got into tubes that it was done properly. Now days it is a matter of degree.dbx_3BX_hificanada.jpg

I have a similar DBX box in my garage ... didn't much care for DBX ... or Dolby for that matter.

And as far as tubes and dynamics capability is concerned ... well ... to my ears they are not exclusively mutual, some of the best "dynamic" ("loud & soft and everything in-between") systems I've heard were SS designs, that's coming from someone who thinks tubes are wonderful musical devices.

Perhaps I owned the wrong solid state.:b

It is enough for this discussion that you acknowledge the existence of the phenomenon.

As I said, perhaps I didn't explain myself clearly, but a couple of systems which come immediately to mind were the Peachtree/ZuAudio and the ZuAudio room itself at the last 2 RAMF's.

Once again an attempt to bring things down to the distortion bogey man while ignoring relevant, empirical measurement and listening criteria
