ACMEE MF02S: Digital player on one ES9038Q2M chip

ACMEE MF02S is a new digital player in which the power and amplification circuits have been significantly redesigned compared to the previous MF01 model. The manufacturer states that instead of following the hype path and installing 2 or even 4 DACs, they took the path of maximum optimization of the circuit in order to make the most of one ES9038Q2M chip.

DAC
The DAC chip used in MF02S is a single ES9038Q2M decoder chip. With the support of the above-mentioned power circuit and audio circuit, its performance can be fully unleashed. Regarding our abilities in this field, we are sure that you also feel something in the MF-01.

Volume Control
MF02S volume control uses imported Panasonic 32-point position encoder, which has long service life and good paragraph sense. The volume knob has a fine knurl, and the moment you touch it, you can turn it several more times unconsciously.

Durable Body
The 6063 CNC aluminum precision carving process, sandblasting anodized aluminum is delicate and smooth to the touch, and the stable and durable body is durable.

Simple
Clean and comfortable listening experience, simple and convenient operation, smooth non-touch screen. A good player shouldn't be too complicated.
