HiByMusic small-sized Amp DAC domestic genuine product.

Purchased in June 2024, this is a compact amplifier DAC.
It features dual ESS ES9038Q2M DAC chips.

Despite its compact size, it boasts high-performance specifications.
It adopts an all-metal body made of aluminum alloy and is powered by bus power, eliminating the need for charging.

I used it a few times with the Hifiman Sundara.
I felt the sound was similar to the Onkyo DP-X1A. The treble is very clear.

It can be used in various environments including Android/iOS/Windows/Mac.
The side of the unit features a 30-step hardware volume adjustment button.
(Physical buttons: Play / pause (twice → next song), volume +/-)
All accessories are included.
