Wyred4Sound uDac-HD

Read a few reviews of this DAC/Amp and it seems very interesting especially if you are looking for one that can be eithervAC powers with a Class A amp or USB powered.

Does anyone have any experience with it?

Oh and would this be an upgrade to DFR?

I second the question. I really like my Wyred4Sound integrated amp, and would probably buy more of their stuff.
What’s holding me back is support for Roon/Tidal/MQS formats that I’m not sure I care about anyway.
