Product Description

NuPrime’s new Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology. 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 in a small, handsomely designed home stereo component.

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. This is further complemented by an innovative volume control design that positions a single resistor in the signal path for each volume setting. The “switched resistor” design is implemented with FPGA chip so volume changes occur in 99 precise 0.5dB increments for each input’s individually adjustable volume level. Precise level matching is a breeze, as is the user’s ability to make comparisons of music sources.

By utilizing discrete components in NuPrime’s ULCAM circuit, the signal can be 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, well beyond the compact disc’s 44.1kHz sampling rate. In addition, NuPrime’s SRC IC chip provides FPGA processing for ultra-low jitter and distortion rates.

Completing the ensemble is NuPrime’s new linear power supply with its high-efficiency toroidal transformer for reduced high-frequency noise and strengthened low-frequency performance. The damping effect of the NuPrime isolation feet absorbs and cancels vibrations that degrade audio performance. The overall result is unprecedented transient speed and an almost shocking level of dynamic impact.
