Well this little blighter landed with me today:
https://www.amazon.co.uk/Optoma-NuFo...ds=nuforce+dac
It's tiny; it looks great and sounds bloody good too! Very impressed with it so far; has a detailed and open soundstage, not too bass-dependent like the NAD D1050 was, but not as taut and punchy as my HRT Streamer; very much somewhere in the middle!
If you're after a very small footprint DAC and headphone amp for you device or desktop system; I'd say go for it
