DScopeIII is also widely used both for lower price and much easier user interface compared to all AP System 1 and System 2 models (in the APX models they finally fixed this). But since AP is the industry standard it seems obvious that companies whish to have one, for generating industry standard plots and last not least, as a status symbol. Sometimes they are there to show off only and not used to really do some work with them (same thing I'v seen with expensive Klippel speaker test systems gathering dust).Wow, I haven't seen those. For what I know most companies like those just got dscopes. What about the software part of that thing? Similar to original?
The US-$ 25k one? I doubt it. But I may be wrong. The Khadas folks do, that was the 1st time I thought this site shouldn't just double check their measurements on the same machine.
Both Khadas and Sabaj sent the items in, it was not someone "discovering" them. It is not the right "ethic". Edit: But it would be ethical if they paid (significantly) for maintenance the site if they want to doublecheck their measurements.
I still don't see the added value for them and for us to double-check their AP measurements at ASR other than seeking publicity and higher sales. Amir said he is fine with that so that's ok then.Understand your doubts, but the other manufacturer like Topping and Okto also have sent the product to measurement. Your question should not be directed only to this product.
I hope more manufacturers send products for review and measurement, more data will give us more comparisons. This allows us to "notice" it. And thanks for what Amir have done.
If you want to check the emissions of your brand new Q7 and you use the same test equipment than Audi uses in it's factory you are just repeating the measurement and the results can't be other than identical. I don't see where this is excellence.
No, they were not independent until they used different equipment than the mfr. That's the point. When the U.S. started measuring under different circumstances they started getting the clue.
Exactly, the U.S. used different methodology. They didn't rely on the tales provided by Bosch.
European authorities were supposed to be independent and measured wrong during many years until the US told them how to measure well.
Then why other companies like sony or schiit, they have AP, but did not design a DAC with thd+n 119dB?If ASR uses the same equipment and the same methodology to "test" whatever product has been sent in by let's say Sabaj or whoever, the only thing ASR is certifying is that Sabaj, 1) yes, they read the AP manual and, 2) yes, they can handle the AP.
The good or bad results the gear obtained is nothing new, that was already done by them. There is nothing "Excellent' with that (other than merely double-checking).
If this is the mission of ASR, that's ok, and I was wrong.
Do you know what measurements are done here? Is there imd graph in the spec? Is there distortion of different loads for headphones output? Is there distortion vs frequency? Is there distortion vs power? Is there j-test graph? Tested by same equipment doesn't mean we get the same set of measurements. Have you ever measured anything, do you even know what these measurements mean? Did you even read the measurements?If ASR uses the same equipment and the same methodology to "test" whatever product has been sent in by let's say Sabaj or whoever, the only thing ASR is certifying is that Sabaj, 1) yes, they read the AP manual and, 2) they can handle the AP.

Plus there are companies like audio-gd who has published ap graphs which shows superb performance but turn out to be worse than apple dongle.If ASR uses the same equipment and the same methodology to "test" whatever product has been sent in by let's say Sabaj or whoever, the only thing ASR is certifying is that Sabaj, 1) yes, they read the AP manual and, 2) yes, they can handle the AP.

Never heard audio-gd measured on AP and published AP figures. In these cases ASR is using different equipment.Plus there are companies like audio-gd who has published ap graphs which shows superb performance but turn out to be worse than apple dongle.
If one Mfr is cheating and publishing wrong AP results, .....I mean, such a behaviour will happen only once if it wasn't a (big) mistake. After a 2nd "mistake" this Mfr is done, similar to what happens now to Shiit.Did it ever occur to you there is a 3rd option ASR is also testing?
3) yes, they published correct results
You don't seem to understand that one fo the purposes of independent testing is to verify the figures published by manufacturer.
