NuPrime Audio IDA-8 Integrated Amplifier

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 in a milieu of un-measurable noise. The IDA-8’s spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to be believed. 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 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. The listener’s initial reaction might very well be “I can’t believe my ears!”

The IDA-8’s low noise floor is further complemented by an innovative volume control based on a thin-film resistor design that positions a single resistor in the signal path for each volume setting. The “switched resistor” design is implemented with FPGA chip. 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. Most class-D amps switch at 300kHz or lower. 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 (patent pending) absorbs and cancels vibrations that degrade audio performance. The overall result is unprecedented transient speed and an almost shocking level of dynamic impact.

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%. The IDA-8’s frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights. The IDA-8’s features and specifications have few equals. Just one audition will convince you that the IDA-8’s performance and sophisticated styling are rarely duplicated at any price point.

Features:

Ultra-Linear Class A Module (ULCAM) achieves audiophile-quality sound 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 (co-developed with IC vendor) provides DSP processing where Input signals are up-sampled to mega hertz before down converted to the targeted sampling rate with ultra-low jitter and distortion.
