Octave Music Don Grusin High Resolution Music Analysis (Video)
Miska has posted measurements on a few forums over the past many years. Like he said, you need to look around. Even various threads on ASR. Join those threads and ask questions and others with the time can answer. His audience must not have the most basic knowledge of signal...
It is amusing that everyone put the focus on ultrasonic noise without paying attention to stuff below 20kHz. Even Miska's trusted AKM DAC with his trusted modulator and his trusted Prism analyzer showed that DSD256 is about 3dB noisier than 44.1k PCM, so no more excuse about ADC aliasing and such. If the rise of <20kHz noise is really caused by ADC aliasing, then it simply means DSD256 is still noisier than 44.1k PCM, even in a "Miska approved" environment. Archimago got similar results as well:
Do you need linear power supply for DACs?
The tests were done with the same SoX DSD signal with the same modulator settings, so all differences were originated from the DAC. All RMAA tests were done with the ADI-2 ADC, so with this factor being constant, all differences were originated from the DACs under tests. You just don't seem...
Regardless of audibility, the whole DSD upsampling thing is simply a waste of time.
