You fail the audio resolution test quiz. If we compare PCM and sigma-delta coding, the sampling rate is not a desicive factor. In PCM the value difference between samples can be 2 to the power of bits. In 16 bit sampling that is something like 65000 units. In DSD the sample value is one bit. If the sampling rate is 64 times higher, DSD can put ... more

What this actually says is that you do not know or understand anything about digital sampling, and the basic difference between PCM and sigma-delta sampling used in DSD. Sigma-delta does not work at all without extremely high sampling rate, it is not a sign of quality. DSD sampling rate is so low (yes, much too low for decent sigma-delta) that ... more

I find it funny that 44.1 kHz PCM recordings get the highest marks for sound quality, again and again. Can you not hear the difference? The recording is great, by the way. At least when listened with smooth headphones like Sennheiser HD800. ... more

Unbelievable. you have not colored all the pages of your preschool audio coloring book, or you would know already that there are no steps in the signal put out by the DAC, be it sourced PCM or DSD. Also 24 bit PCM gives 144 dB dynamic range (theoretically, usually limited by converters), DSD "only" 120 (also theoretical, worse in practice), plus ... more
