RE: Chord up-samples?

From the article, stated by Chord engineer John Franks.....

It uses very advanced digital sampling and whereas a typical industry DAC chip would have maybe a 125 or so sampling filters, in the Dave we have 166000 digital sampling filters, it's many orders of magnitude, more complicated.

I don't know how Franks came up with the "quantity" of digital filters in a DAC..... Unless he's referring to the number of calculations performed by a digital filter, over a set period of time.

The ultimate idea of the DAC is to reproduce the original waveform in all its complexity and perfection. The idea of the DAC is not to reproduce digital samples, which is that waveform. And if you can do that by taking as many samples as possible, faithfully reproducing all of the timing information which is locked in that signal, the strange thing about our brain is that it seems to be able to resolve information that technically our ears can't even hear.

I thought almost all DACs process "as many samples as possible".... At least for CD playback..... A DAC cannot process "more samples" than what's on the digital media itself.

People often say how wide is the soundstage but it has no depth because their DAC isn't measuring enough samples to give enough timing information to the brain.

This implies that a lot of DACs "omit" some of the data samples on the media..... This would be a damning indictment of the digital audio processing industry if this is actually the case. But I don't think this is actually the case.
