Description
The XDP-300R supports all your current audio from MP3's to streaming music from your favorite internet apps. With playback support for up to 11.2MHz DSD, 384kHz/24 bit PCM, FLAC, ALAC, WAV, AIFF, and MQA it is possible to enjoy many existing Hi-Res audio formats. Equipped with both 2.5 mm balanced output and 3.5 mm headphone output; audio can also be output via Micro USB-B/OTG digital output, and wireless output to connect the XDP-300R offers a wide selection of headphones and peripherals. Compatible Formats: DSD(DSF/DSDIFF)/FLAC/ALAC/WAV/AIFF/MQA/OggVorbis/MP3/AAC.Incorporating twin unit ESS Technology DAC "ES9018K2M" and AMP "SABRE 9601K" each allows for extreme high resolution audio and component audio design philosophy while still maintaining a realistic power envelop for a portable device.
Complete separation between the audio circuit board (DAC & AMP) and CPU board to allow for internally separated construction. Within the DAC & AMP board, the audio circuitry and switching power are distanced as far as physically possible to limit the effects of noise. The DAC & AMP have their own capacitors to provide a clean audio signal with its closed loop design. Attention was made to circuit design to keep digital noise from getting in between you and your music.
Balanced output via the 2.5mm 4 pole supports the standard "BTL" drive as well as "ACG (Active Control GND)" drive. ACG drive is a different form of balanced drive where the amp's COLD side actively drives to create an ideally stable GND. Power gains and increased sound separation associated with balanced output are repurposed to create increased stability for a clean signal and a greater sound clarity, especially compared to unbalanced drive.
