Who this is for: You listen on IEMs or headphones that cost more than your phone's DAC deserves. You want balanced output without carrying a brick. You've compared dongle DACs on Head-Fi and know that dual-chip marketing gimmick when the implementation is right.
The real difference: Most sub-$80 dongles share one chip across both outputs or only offer 3.5mm. This unit gives you dedicated decoding per channel through dual chips, with a true 4.4mm balanced stage the same topology that $200+ desktop units use, in a form factor that fits between your phone and your case.
