I have one. I sourced it from the UK; I don't know if it's available in the US yet. The wall wart is universal, so I think we'll get the same unit here in the US when it does arrive.
I got it in anticipation of a Red Wine Audio-based setup, but right now have it feeding an April Aura Note via the Note's AUX input, into Omega single-driver speakers. The Note has its own USB input, and I've also messed around with driving it with a NuForce uDAC and a Centrance DACport. The rDAC is better than any of them. Most noticeable to me is a large, really well-defined soundstage and a really crisp presentation. I'm not noticing any particular coloration, it just sounds really good.
Talking with others who have more experience than I do, it seems that you need to get up to, say, the PS Audio DL 3 level to do better than the DACport, and the rDAC is better, so I think it's in that neigbhorhood anyway.
I got it because it's small and well-specced - good components and asynchronous USB, at a relatively low price. I'm very happy with it.
Hope that helps.
