Engineered as an all-in-one digital audio centerpiece, the DM15 functions seamlessly as a standalone CD player, high-power desktop amplifier pushing up to 1100mW per channel into 32 Ohms, an asynchronous 32-bit/384kHz USB-C DAC, and an aptX Lossless Bluetooth transmitter. At the heart of its analog conversion stage lies a dual AKM AK4493S chipset with Velvet Sound architecture, delivering smooth musical warmth, expansive acoustic staging, and remarkably transparent low-level detail. Featuring dedicated 4.4mm balanced and 3.5mm single-ended headphone jacks alongside coaxial, optical, and line outputs, it allows direct CD-to-USB ripping in uncompressed WAV format. Encased in a precision-milled aluminum chassis with a transparent tempered glass lid to watch your discs spin, the DM15 incorporates patented Desktop Mode power isolation and a high-voltage 4700mAh battery for up to 6 hours of continuous CD playback.
