Quite ridiculous. All these measurements are irrelevant to how the gear sounds? You are embarrassing yourself now and don't know it.I don’t have the equipment. But Amirm does ! If he dares to make the right measurements… that the most difficult part. Changing his mind to make the right thing.
Frequency response, sinad, jitter, linearity, channel matching etc… all these measurements are perfect to get an idea of the engineering of a gear. And they’re all irrelevant to how this gear sound.
He already shows the filter responses, distortion, I'm guessing you don't get how the time domain works or you would not say this.For the sound itself, Amirm should focus on the harmonic distorsion (and understanding them), interpolate filter, analog time domain etc…
Yes, Amir has done tests of DAC that use the harmonic compensation and some that don't showing us the results of it both ways. I'd say it impacts the preciseness of the reproduction, but I'm not sure without it the sound you can hear is impacted.For example, the ESS9038 (and others chips of ESS) has an option called « harmonic compensation ». If it is active, it reduce the harmonic distorsion drastically. Some gear (like project) let the user activate it or not. (Many Chinese gear always use this option on, solely to get better results in measurements). And this option impact the sound. I don’t know if it a good or bad thing and I don’t care.
And we are trying to tell you that first, you don't seem to understand his measurements, and what effects the sound is the signal coming out of the device while in use. The measurements provide the performance envelope of DACs well enough there is little left to wonder about that can effect sound. You are going by sighted listening where yes many things effect the sound, time of day, knowledge of what you are listening to, how you feel that day, whether you've imbibed a little or not and on and on and on. None of that is actually due to the device itself or the resulting sound in nearly all cases.The fact is there is many things that can affect the sound, and cannot be see with a frequency response or the average noise floor etc…
Try this little listening test. I have posted it several times in this thread alone.
Serious Question: How can DAC's have a SOUND SIGNATURE if they measure as transparent? Are that many confused?
...that is the best take on the subject I have seen so far... ...it is clear to any thinking person that there are asspects involved we have no way to measure... ...it was just stated there are only three asspects measured at the current state of the art...

8th generation copies versus original file. If DAC sound different, I'd think going thru a DAC 8 times and then going thru an ADC 8 times (ADCs would sound different too) would magnify the difference by 8 times. Should be a piece of cake. Do the tests honestly without peaking at results and see if they sound obviously different to you.
