Mine came from Fosi to my UK home in around a week, with full package tracking available on their site (looks like three days to the UK and then two days to the house!)
I had no idea what to expect, but the packing box is smart, the inner sliding out to reveal the unit, which is quite small and superbly finished and presented I think. Also packed is a very short USB C-C connector and an A-C adaptor which is a great thing to find.
I already had a 3m USB 3 to C cable (a posh looking LDLrui thing from Amazon which cost a massive £13.99) from the PC's USB3 sockets and I also bought a flexible half metre 3.5mm - RCA cable for it (again from Amazon, a 'Primewire' type at £7.99, very high-end
).
The amp offers a 50k input impedance on the line inputs and unlike the US spec Apple dongle, which doesn't have enough level really unless the volume control is whacked right round when used this way (unintended in fairness), this little Fosi unit is exactly the same output as a CD player, give or take, as-is the SU1 which is now destined for better things
All I can say is it 'sounds' great and although audio memory is pathetic, using the existing CD player as crude reference, the Fosi and SU1 'sound' exactly the same, which is exactly how it should be. The volume up and down buttons don't work with unit used this way, but mention is made of that in the instruction book, which seems well written.
So, for fifty quid or so including exit cable and Fosi promotion, I'm a very happy bunny and very impressed with this little box, which tucks away behind the unit the system's sat on. Tiny orange led to say it's receiving power and it IS fully usable as a very simple USB (C) desktop dac which performs incredibly well too.
I love things like this. Small, well put together and which work so well, showing the entire high end audio industry for the foo peddlers they are (Accuphase want a grand or thereabouts for a sodding great component-filled dac board which I doubt performs as well as this Fosi with hardly anything on it and as for Chord and DCs products at hundreds or even thousands the price!!!). Thanks
@amirm for reviewing it and thanks Fosi for being so fair on pricing in my opinion...
