The FiiO DM15 is a portable CD player with a built-in DAC and headphone amplifier. It is the AKM version of FiiO's DM15 R2R CD player and uses two AKM AK4493S DAC chips. Its five-core design combines a CD servo, a USB bridge, a Bluetooth module, a dual DAC module and an independent MCU.
It plays CDs and can rip them in uncompressed WAV format to a FAT32-formatted USB flash drive while you listen. It also works as a USB DAC for a PC, laptop, phone or tablet, and as a Bluetooth receiver or transmitter. The custom CD mechanism uses a self-rebounding steel ball design for smooth disc handling and stable reading, and an ESP switch helps keep playback stable on the move.
Desktop Mode, switched on at the rear, isolates the battery and powers the player directly from the USB-C port. The body is an aluminum alloy chassis with a tempered glass top window and front lens.
