Best way to output hi res files to DAC?

Come to think of it, USB out would work also as long as there aren't any resolution limitations.

What are the options for high res music servers with USB out?

So no media servers capable of DSD with a digital out? That's surprising given the popularity of DAC's these days.

Jon2020 - Do you know if it's possible to pass digital out before the DAC on the Marantz. And what kind of digital out does it have? The problem is my Wadia integrated also does an automatic uprez with it's DAC tho not to a full DSD. I'm not sure what effect two different DAC stages might have.

Very interesting. Unfortunately one quirk of the Wadia is that all the inputs (analog or digital) are up sampled through the DAC. Fortunately the DAC is very natural and organic sounding. Typically though the digital input sounds better than analog to me.

It doesn't uprez to DSD but does accept DSD and DSDX2 (or whatever it is) natively. Have you done much more with it than just play hi rez files through a flash card? Have you tried loading music on the internal hard drive? Any quirks so far?

No idea why Wadia also runs the analog through the internal DAC. But it sounds quite good and natural in any case. They jammed lots of good technology into a small unit - and it works very well.

The Aurender X-100s does look like what I'm looking for. But without a DAC the $3K price tag seems pricey at least in sub 12K systems like mine.
