Significant upgrade from Moondrop Dawn Pro 2.

The amp stage is noticeable. Even in eco mode it presents a bigger more 3d stage, better bass definition and cleaner background than the Moondrop Dawn Pro 2. Better transparency, focus and natural liquidity.

Punches well above it's weight class

Powerful enough to drive my Hifiman Sundaras (30 Ohm) for a really high quality listening experience whilst around the house through my phone.
Sounds incredibly clean and I love the details coming through that a cheap dongle or motherboard audio just can't get.
