Or maybe you listen directly to your DAC? I have to put it through my speakers and room first!?????????![]()

Which has nothing to do with it. What goes in determines what comes out. It would be fine to measure what comes out, but you can measure more precisely what goes in. You can do it either way. You are wasting your time if you do. But rather than conjecture do it. I've done it. You can do if it that is the only way you will believe it.Or maybe you listen directly to your DAC?

I don't want to do it. That's why I was asking. If I wanted to do it I would simply do it (I do have the equipment and software and have measured my room before to create Convolution filters in Roon to improve my room response).Which has nothing to do with it.

So to answer your initial post, isn't the obvious pair of answers "no" and "no"?I don't want to do it. That's why I was asking.

When I see something that doesn't deserve my time and attention I just move on. Thanks for your valuable contribution though.So to answer your initial post, isn't the obvious pair of answers "no" and "no"?

If it was worth your time and attention to ponder and post, and within your abilities to investigate, why aren't you doing it?When I see something that doesn't deserve my time and attention I just move on. Thanks for your valuable contribution though.

Thanks for your interest in my personal life. I am away from home for a long period. I normally only have one single DAC at home (not counting with my TV and so on). I have other DACs with me right now but don't have the microphone.

I'm sure you have at least 2 devices with DACs in that you can test.

Yes. The question was if it was meaningful to do it after speakers. If we get a equal FR from two different DACs from a room measurement I guess it proves that no DAC has stronger bass or pronounced mids than other. I think it would be valuable to show it, not only theoretically explain it.Perhaps the gist of my post was not evident.
If you measure a low-level electronic signal, the level of discrimination makes characteristics obvious, like the apple in the oats bin. But after both the oats and the apple have gone through the horse (the speaker), the desired level of discrimination no longer exists. Therefore, as others have said, if you wish to achieve meaningful results, measure before the horse (the speaker), not after it, or your results will be meaningless.
I would like to point out that your original post was about measuring differences in DACs, not speakers.

You have more DACs on your travels than at home? Now I actually am interested in your personal life!Thanks for your interest in my personal life. I am away from home for a long period.

Would measurements of a couple or three DACs convince you or are you requiring it be done with speakers?Yes. The question was if it was meaningful to do it after speakers.

If you measure it on the DAC some people will say: but did you listen to it? If you measure room frequency response you are measuring what you are hearing. No one listen to DACs. I do understand the logic that if the FR of all DACs is the same it can't have an influence of a room frequency response but not all will have the same opinion. Now I think it's impossible to anyone deny that two different DACs that have the same exact measured room frequency response can have different audible bass/mid/treble response.Would measurements of a couple or three DACs convince you or are you requiring it be done with speakers?
Man, you have to go out some more! Try to spend 11 months away from home per year and see where you'll need more your DACs..You have more DACs on your travels than at home? Now I actually am interested in your personal life!
“Thread closed?“
Please do.

That I can tell you that doesn't have a significant effect. You do a room measurement in about 15 seconds. I've done several consecutive measurements before and got exactly the same response. Very rarely I had some variations but in the lowest frequencies. I think the most difficult thing to do with different DACs is to perfectly level match them.The answer has already been given: no. A microphone is entirely the wrong tool for the job even before one considers things like comb filtering, ambient noise, variations in the speaker output as the tweeter heats up, etc.

You set the level in REW. We're talking sine sweeps right?think the most difficult thing to do with different DACs is to perfectly level match them.
No. I was just thinking that are several reviewers that say that one DAC has stronger bass and other more pronounced mids and that a room measurement should be the objective way to desmistify that (or to confirm it! )
Right, but it's difficult to set the level exactly the same. Normally I do it playing Pink Noise in order to get something around 75 to 76 dB. If one DAC is at 75 and other at 75.5 dB I guess that it's already a somewhat visible difference (altough it would be across all the frequencies).You set the level in REW.
