Small tweaks to popular design

M6 Pro adapts the signature look of prior Shanling players. Minimalistic style with curved glass panels and robust aluminium frame, combined with round edges and pronounced cutouts for even better comfort in hand.

CPAF Technology

In order to solve the group delay problem of a traditional low-pass filtering, our engineers designed a new audio circuit, based on an advanced mathematical models, utilizing the CPAF technology - Constant Phase in All Frequencies. This design was inspired by the amplifier from original Shanling M3, our very first portable player.


Four units of Texas Instrument's high-speed buffer are positioned at a driver stage of the amplifier, significantly improving output currents.


Low pass filter of the amplifier was upgraded to the Texas Instrument's OPA2211, for a better matching with the pair of ESS DACs.
