ayon integrateds--USB input... for what?

I see some of their integrateds listed as having USB inputs--but am unable to find anything more about it in reviews or the company's website.

The obvious answer would be that they have an internal DAC that you can simply hook up your computer to...but that seems kinda kludgy for such high end equipment. Don't get me wrong...I like the utility of it, a lot, especially if it could eliminate the need for an expensive DAC...but...never seen such a thing on any other (high end) pre or integrated.

Anybody know about this...Anybody have experience with its use/quality, etc.
