I've deliberately stayed away from the DirectStream discussion because I'm not a big fan of PS Audio. They make the occasional good product - loved their old Digital Link III, enjoyed some of their various amps over the years, and the PWD is pretty good too (but overpriced imho).
But there's been lots of duds in there as well. Between the atrociously poor reliability of the 220v Power Plant Premier, the terribly etched sounding NuWave DAC, and let's not forget the Noise Harvester... I find it hard to trust them.
PS Audio's marketing team is highly skilled, but not always convincing. That applies to the new DirectStream DAC. Oddly labeled block-diagrams show their circuit as being simpler, and therefore better, than some random unnamed ESS Sabre chip... but note how the PS Audio diagram leaves off things like power supplies for the appearance of less clutter. I pointed it out in the comments HERE and designer Ted Smith explained it away as a misunderstanding.
I'm just not convinced their "new technology" is the big deal they make it out to be. Like every major release from them, it is supposedly revolutionary, but I'm not so sure. Will happily eat my words if/when I hear it and it blows me away.
