I have one as a player not too bad, under powered for full size phones though. I too have the Hi400 and think they sound dull unless i add in a bit of amping.
Problem here is that there is no line out as yet. No dac out or at least not that I can get it to work. Did get it work with win7, win 10 is possible but you need to see hidizs website and follow a crap load of set up stages.
Wi fi and Bluetooth are functional but need work.
Basically I would only buy if you are looking for a nice player not as a dac or streaming device.
SStasWould this be dac in from a phone or from a computor. Just curious because no one on thier forum has mentioned using it as a dac from a phone. Win7 requires downloading seperate drivers from Hidizs web site and it certainly is nothing special and not worth the bother. If you have managed to get working from an Andoid phone kudos to you because i could not.
DanAutoTechAhh, i have not tried from an external DAP or my iPhone yet! Just windows 7 and 10. But it was bad from the PC, so i can’t see there being any benifit for a phone. I use a Caymin c5 Dac/amp for my phone, or a portable amp on the AP200, for A sexond option
