To be honest I didn't like UD 110 too much, midrange is not enough wide for my taste.
Good bass, decent treble but voices are not enjoyable
But I can tell you I tried with:
Mac imac it was, perfectly working
NAS Synology 213 working perfectly with an USB extension, without some EMC glitch
Samsung S3 doesn't worked
iPad worked with 1 USB adaptor and 1eur USB hub .. Funny
