The NuPrime DAC-9X is engineered with advanced technologies to deliver exceptional audio performance:

• The Heart of Your System: Features dual ESS Technology 32-bit audio DAC ESS9028Q2M chips, independently decoding left and right channels to enhance channel separation and reduce overall noise. Utilizes Vishay professional film MELF resistors for superior sound quality.
• Advanced Power Circuitry: Employs a low-noise power supply with anti-vibration processing to minimize AC hum. All onboard power circuits are designed for minimal noise interference.
• Native MQA Decoding: Equipped with MQA technology, allowing for the reproduction of the original master recording sound from MQA audio files and streams. Front panel LEDs indicate MQA stream detection:
  • Alawọ ewe: Indicates playback of an MQA Authentic file.
  • Buluu: Indicates playback of an MQA Studio file.
  • Magenta: Indicates playback of an MQA ORFS (Original Sample Oṣuwọn) file, approved by the artist/producer in the studio or verified by the copyright holder.
• Ultra-Low Jitter and Distortion: Incorporates the "NuPrime SRC" DSP chip, co-developed with an IC vendor, which upsamples the input signal to MHz before downconverting to the target sample rate, achieving ultra-low jitter and distortion.
• Asopọmọra Rọ: Includes an expansion port for optional Bluetooth receivers or WiFi audio streamers.
• Iṣakoso pipe: Features full microprocessor control with memory retention for settings.
• Native DSD Playback: Supports native DSD playback via ASIO2.1 and DoP methods.
• Minimal Noise Floor: Utilizes ultra-low noise JFETs in the input stage to achieve the lowest possible noise floor.
• Àtúnṣe Ìwọ̀n Ẹnìkọ̀ọ̀kan: Allows for individual volume adjustment for each input, enabling precise matching of source levels.
• Asynchronous Transfer: Employs an asynchronous transfer method for optimal data integrity.
• Agbara Lilo: Significantly reduced standby power consumption.
• Wireless Receiver Support: A USB Type-A port provides S/PDIF data and 5V power, allowing connection to external wireless audio receivers (e.g., NuPrime Omnia WR-1, BTR-HD, Stream Mini, Stream Mini DAC) using a single standard USB cable.
