Use this as my daily dac/amp connected to a chromebook with Tidal and Amazon Music HD, Hidizs AP80 dap. Converted most of my IEMs to balanced cables (2.5 mm) and use a 2.5 -> 4.4mm adapter to connect to my DH80s. On my phone I use usb audio pro.
A great upgrade from my FIIO BTR5. More balance power and cleaner sound. I cycle through my IEM collection since I love all them all and find them all to love this DAC/AMP (f9 pro,hidizs ms4,shozy form 1.1,bqeyz summer, and a few others). MQA works great on my phone with usb audio pro.
Single ended HiFiMan 4XX lacked the bass slap a higher powered desktop amp provides but a headphone with a normal driver it sounds fine.
Fantastic value.
