This little thing is growing on me more and more...
Tried it as a transport with mojo2/ lcdx ...
Worked flawlessly, and transports do make a difference to audio, I don't know why but there is a difference with different usb source's, hidisz ap80pro did not sound good with mojo2 as an example...
This sounds clean and really tight and maybe ( maybe new placebo)
Cleaner and tighter than my Sony Xperia phone which up until now has been my favourite transport .

I also tried this with some meze 99 classics straight out of 3.5 mm (sorry don't have a balanced cable yet for the meze, it's on its way)
And again it sounded very good!

It's actually starting to surprise me which is obviously a good thing...
I do think out of the box treble is a bit edgy but it settles and the whole thing becomes more cohesive..
So to sum up it's a definite keeper and doing everything I want with ease, it sounds good and amazingly good for its diminutive size , as I posted before you will get better audio from say an ru6 dongle but do not let that take away how good this is and actually sounds , it's more convenient and not draining your phones or powering source battery ..
I was going to try the m1s too and may still do but after using and it settling for a couple of days I honestly may not bother.....it's ticking all the boxes.
Only some small gripes..
As I said before I would like to see album art in the companion app ...
And also that the folder line when highlighted to select actually pans left and right to be able to see and select more easily.....this one is a niggle but for such a small device an essential one IMO
