Just an FYI guys, I bought this to pair with my Shure SE846, after I had already bought the Fiio X3, but couldn't get the X3 to properly recognize ALAC track tags. I just got it a couple of days ago. I loaded up the latest firmware 1.2.8. I have had two instances with the volume spiking and have also had the unit hard lock randomly just by picking it up. I also hear loud hissing in any of the gain settings, although it gets better with higher gain. This thing seemed to have alot of potentital versus the Fiio X3, the UI actually function properly unlike the Fiio, but I am not going to take the chance of damaging my $1000 IEM's with it. My goal is to not use an amp with the SE846 and high res DAP. I may bite the bullet and get the HM-901, as everyone considers it one of the best if not the best.
