I'm looking for something reasonably priced (under $1k) to measure both USB DACs and headphone amps. After some readings, QA401 seems only useful...
Sorry, not really sure with the question. You mean quality control? Since I start with measurement, I saw many IEMs has inconsistent tonality...
I see. Thanks!
As mentioned earlier, I tested 2 units of AK T8iE Mk2, both have audible tonality differences. The demo unit is much better, more linear with good...
I'm interested to get this QA401 as well. Any QA401 user here? I wonder if it can be used as regular audio interface for playback and recording.
My measurement of Shozy Zero using MiniDSP UMIK-1 measurement microphone and DIY acoustic coupler, before and after burn-in. All channel measured...
Totally different family of tonality. DITA Truth is brighter with a treble peak that annoys me a bit. While T8iE Mk2, the demo unit I mentioned,...
After using the demo sample of T8iE Mk2 for a few weeks, and finally bought one for myself, I have a mixed feeling about it. The demo unit sounds...
I love to watch RMAF seminar video archives on YouTube, but I found sometime the audio quality of the video was really poor. They discussed...
Cycling the input selection sometime works to fix the issue, sometime doesn't. The issue happened on both USB and Coaxial SPDIF I tried. Noted...
Yesterday I borrowed a Bifrost MB from a friend. When testing it, I heard abnormal glaring treble distortion when playing high resolution flac...
Right, if just zooming on the transition the frequency makes no difference. Will try later when I have time, with lower frequency square waves.
May I know what's the reason to use low frequency like 10 Hz? Isn't it easier to observe the transition edge on oscilloscope using higher...
Recently I checked the Geek Out 450 output on DSO to check the square wave output from the 2 digital filters. I have 2 GO 450, the Black one...
