How can DAC's have a SOUND SIGNATURE if they measure as transparent?

[sonitus mirus]

Some falsely claim a duck's quack won't echo, which would be a quacking great feature for any DAC!

It's a forum, people have opinions!

Some people use nonsense as a way to relieve stress. I have no way of knowing for sure , but I would guess that there are members here with quite a bit of stress in their lives. For them, silliness can be ... well, therapeutic.

It is a nonsensical or, hopefully, sarcastic topic name to some serous people.

If the major difference between one DAC and another is mostly the strength of the signal, how can I know if a DAC I choice will give a good signal power to my setup?

Is there some numerical criteria depending on the amp or the input impedance? I’m confused about this point.

This is difficult to do without knowing exactly the output impedance of the DAC. However, you can make a good guess depending on trustworthy the maker is and depending on what kind of output (TRS or RCA?) it uses.

I have active monitors, XLR input. I was considering Topping D50 iii because I want spdif input for the TV and has balanced outputs also. More or less is some price than others from the brand and was measured by Amir.

Should I trust the power output match well my Genelecs?

Post edit: I was considered two in one Wiim Ultra streamer and DAC but this has RCA outputs

This may help you:
Why is transient analysis important?


The main purpose of transient analysis in Physics is to understand how a system responds to sudden changes or fluctuations over time. Its applications are widely seen in electrical engineering, particularly in studying circuits and systems during the switch-on phase.

You seem to believe that the sort of testing @amirm performs here doesn't sufficiently (or at all) characterize dynamic performance, that it is limited to static conditions. As a chemical engineer I'm entirely familiar with the difference between thermodynamics, which deals with equilibrium conditions, and kinetics, which deals with how quickly a system arrives at equilibrium. But I'm pretty clueless about electrical and electronic theory, probably as a result of the complicated mathematical operations involving imaginary numbers. It never made sense to me.

I'd love to see an explanation from one of the many experts here as to why the measurements we see here are in fact sufficient to describe amplifier and DAC dynamic behavior, as apposed to static behavior.

Just for the fun of it, check out what the waveform of a multitone looks like. It’s is really a dynamic and highly variable signal. If there were issues, it would immediately show up in the resulting spectrum.

First, define exactly what you mean by "dynamic" and "static" in this context. Definition, not analogy.

Dynamic refers to time-domain behavior evaluation, whereas static behavior is time-domain-independent.

 

[SIY]

Dynamic refers to time-domain behavior evaluation, whereas static behavior is time-domain-independent.

Then that's every measurement which is presented. They do not involve DC.

 

[Blumlein 88]

So is a Dirac pulse repeated every second static while one repeated at irregular intervals dynamic?

Absolutely incorrect. A constant 8-Hz tone is time-independent: in other words, it does not vary over the time domain. But it's not DC.

That's an interesting question that I don't have an immediate answer for. I guess I'd have to say if the pulse is identical over time, it could be regarded as static. But we're getting into semantics here.

Measuring output in the time domain of a component to a pulse input certainly is a dynamic measurement.

 

[voodooless]

That doesn’t work like that. Time and frequency domain are just two sides of the same coin.

Somehow people think that DAC have issue with all kinds of strange signals. That’s just nonsense. There is no reasonable reason to think so.

It is a possible real thing so not semantic. What it shows is I think your idea of static and dynamic is semantic in the way your are describing it. Do you consider multitones static or dynamic?

A sine wave varies in every moment in time.

Life works like that: we operate in multiple dimensions. Chemical equilibrium is constant over the time domain so long as pressure and temperature are also kept constant. None of my questions arise out of a belief that "DACs have issues with strange signals." That's not relevant to my inquiry.

It is? I sorta thought it was proportional to sine(16pi x t)?
