The trouble with what is shown is that it does not deal with anything but full level signals that are fully filtered. However, if you look at a 1K signal at -90db then you see 3 clear stair steps at 16 bits (Stereophile has been showing this on their measurements for years and years). If you raise the bit level then the stair steps at -90 start to disappear. If you looked at a 16K sign wave at -90 I don't think it would exist. Not enough bits.....this is why 24 bits is necessary....to get the low level signals and especially at higher frequencies.

Even more interesting is that if you use no analog filter and only a 8 times digital filter then you will see stairsteps even at 1K. He is showing a fully digital and analog filtered signal. If you use no digital or analog filter then it really looks horrible.

So...his information is useless except for nerdism. This is why digital has taken us so long to get right....guys like this think it is all ones and zeros........sorry, wrong. Every single thing you do to a digital signal anywhere along its path messes with the SOUND...this is the truth!

There is no myth....there is mystery. And you will only find the magic if you are adventurous. Just now put a piece of constrained layer damping material on the coax digital input jack inside my modified Gustard DAC.....OMG! what a revelation....way more real sound! Let me see you measure that! I can hear it....that is what matters! You can hear it too!
