If the hubs are powerd then it's sure work , but the hubs above is unpowerd but also work ? so what's the hub do to make the ud110 work ?

thanks , is the function of the usb hub is to convert usb 1.x -> 2.0 so it can be used with the ud100 ? If so then all the usb 2.0 converter will work right ?

I can't make it work with my Lenovo K900 , Anyone know If I use the UD110 through a USB Isolator it will work ? thanks

go to stoner acoustic blogspot . the dac chip is pcm5102A

Can wear MA900 for 6 hours , I had to stop for diner otherwise I think I can wear it forever the most comfortable headphone ever

Do you have both of them ? I'm lost here . I want to find a pair which have a same sound signature of my MA900 . Any suggestion ?

I have TDK IE800 which I like them very much but I still feel that they a little thin (empty) for my taste . Is the BA200 fuller than the IE800 ?

That looks great can you post some more detail pictures how you recable it ? I see the cable is run under the earcup how you manage to recable it ? thanks

  Can you also confirm that is it compatible with Android ? thanks

Can anyone please confirm the UD110 compatible with android ? I saw once someone said that the HifimeDIY U2 which uses the same SE9023 receiver work with his Xperia . Arhhh so sick of laptop built in DAC
