NuPrime IDA-8


Ultra Low Noise Class A+D Integrated Amplifier with DAC and Wireless Port

The NuPrime IDA-8 consists of an ultra-low-noise integrated amplifier and digital-to-analog converter that decodes USB PCM 384 and DSD 256. The features, power and performance available within such a compact, well-built and designed unit is a real bargain for the price. The IDA-8’s spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to be believed.

SKU: NP-IDA-8 Category:


The NuPrime IDA-8 consists of an ultra-low-noise integrated amplifier and digital-to-analog converter that decodes USB PCM 384 and DSD 256 with the convenience of wireless audio in a small, handsomely designed home stereo component. With NuPrime’s Class A+D hybrid amplification technologies, the IDA-8 thus delivers the substance and warmth of Class A and the efficiency and speed of Class D amplification.

With all stages in one chassis, the IDA-8 avails itself of the shortest possible signal paths in order to facilitate vanishingly low levels of noise and distortion for a black-velvet background to music. By utilizing discrete components in NuPrime’s ULCAM (Class A) circuit, the IDA-8 has been fine tuned to reduce noise and provide maximum power. The NuPrime amp circuit improves on traditional Class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 600kHz, while most competing class-D amps switch at 400kHz or lower.

Featuring many innovative designs such as the FPGA processing, high efficiency linear power supply and FPGA based switched-resistor ladder volume control, the IDA-8 achieves Total Harmonic Distortion + Noise (THD+N) levels of less than 0.005% while achieving a system efficiency of up to 93%. A frequency response extending to 50 kHz elevates vocals into emotional experiences and similarly, instrumental upper registers mimic a live performance’s shimmering heights.


    • Ultra-Linear Class A Module (ULCAM) achieves audiophile-quality sound, coupled with Class-D’s dynamics, speed and efficiency.  Extraordinary result of THD+N lower than 0.0015% and S/N ratio of -130dB for the preamp stage.
    • NuPrime SRC IC chip provides FPGA processing with ultra-low jitter and distortion
    • NuPrime vibration-free isolation feet (patent pending*) absorbs and cancels vibrations, hence further lifting audio performance.
    • State-of-the-art DAC supporting USB PCM 384 and DSD256, that is also capable of decoding DoP formats via coaxial and optical inputs
    • Analog line-out that can be also used as a Subwoofer output
    • Extension port for Bluetooth dongle (included) and WiFi audio streaming (optional)

    • Ultra-low-noise JFETs used in the input stage for achieving the lowest possible noise floor
    • Volume adjustment in 99 precise, 0.5dB increments, which also memorizes the setting for each input for precise level matching of all sources
    • Advanced, thin-film switched-resistor ladder network for controlling volume, with a single resistor in the signal path at any volume setting
    • USB Asynchronous transfer mode with driver software provided for Windows (driver not required for Mac OS and Linux)
    • Very low power consumption on Standby Mode
    • Includes remote control
