Leaf-audio CMD12 Dual DSD1792 Audio Decoder Fully Balanced Headphone Amplifier Hard Decoding DSD Support for APTX/APTX-LL

Leaf-audio CMD12 Dual DSD1792 Audio Decoder Fully Balanced Headphone Amplifier Hard Decoding DSD Support for APTX/APTX-LL

Features:
- Native hard decoding DSD
- Fully balanced 7 dual operational amplifiers design, with balanced XLR output and RCA single ended output. The headphone amplifier part uses 4 single operational amplifiers for current amplification.
- Dual DSD1792 design, with each chip connected in parallel as one channel, software controlled in MONO mode to improve dynamic and signal-to-noise ratio.
- Paired with an sub card for XMOS, it can be unplugged and plugged in. PCM and DSD are automatically recognized and decoded using the sub card.
- The coaxial, fiber optic, and Bluetooth receiving chips adopt low jitter AK4118.
- Adopting two sets of analog power supplies - for Marantz CD-7 voltage stabilizing circuit, field-effect transistors as constant current and for Darlington transistors as adjustment tubes with stable voltage, strong load capacity, and high output current.
- Assemble with enthusiasts grade parts to ensure good reliability and sound quality.
- Built in fully balanced headphone amplifier, the headphone amplifier is powered by a separate transformer with good dynamics and high driven capability.
- Built in APTX Bluetooth module, supporting lossless playback for APTX and APTX-LL, decoding Bluetooth as coaxial input to AK4118.
- Standard size all aluminum chassis, beautiful and easy to match with other equipment.

Note:
- When there is no signal input from coaxial, fiber optic, or Bluetooth, it will automatically switch to USB decoding.
- Using a USB sound card, pressing next, pause, or fast-forwarding during DSD playback will cause an impact sound. Thanks for your understanding! (PCM playback will not have this problem)
