I haven't read the whole thread, so this may have been asked already, but can anyone answer this:
What IS multibit? What does it mean, technically? How does it differ from delta-sigma? And what does delta-sigma mean too, while we're at it?
Nothing in the Schiit FAQ really covers my question, and I've tried searching on Google too, but to no avail—I haven't found any "layman's explanations" that offer any insight on what multibit and delta-sigma technically mean, just a bunch of ranting about how multibit is better than delta-sigma, but no one says how either of them work, at least in terms that an average reader can understand.
I'm just trying to understand the conceptual difference between delta-sigma and multibit, and why I should bother with a multibit DAC in the first place. I know Schiit doesn't do "hard sells" but this is one thing I'd really like to hear from Jason on, if possible—essentially, why should anyone buy a multibit DAC? What's so great about the technology, and how exactly is it an improvement? And I'm not interested in "it just sounds better" answers, I'd like an explanation that's at least semi-technical or semi-mathematical, since nearly anything in digital audio can be expressed in terms of numbers.... (and fully-technical or -mathematical explanations would be even better, even if I don't understand them)
I recently bought a Bifrost 4490 btw, which sounds really good, so now I'm curious about the whole multibit craze.
