Ultra Low Noise Class A+D Integrated Amplifier with DAC and Wireless Port
The latest advanced digital audio component from NuPrime combines leading edge digital to analog conversion with a statement grade preamplifier and a new hybrid Class A preamplifier with a Class D power amplifier. It is a new type of hybrid integrated amplifier that sounds far superior to anything that came before it. The purity and naturalness of Class A with the efficiency, authority and clarity of Class D. With the NuPrime IDA-8, your music has never sounded better.
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. 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. It's an investment that will provide years of musical enjoyment.
Simple. Minimal. Effective Design.
Inspired by the the expression 'less is more', the IDA-8 from NuPrime is a truly modern audio component. A beautiful chassis finished in either silver or black with only two control knobs and a discrete information display makes it look more sculptural than traditional stereo components of the past. It's discrete and elegant. Refined and sophisticated, while being straightforward and intuitive.
Advanced Connectivity
Connect your laptop or computer to the provided USB port and the built-in DAC is ready to accept digital music files stored locally or through the streaming music service of your choice. Tidal, Spotify, Songza, Deezer and others put you in touch with millions of songs. For a high fidelity experience, high resolution downloads from ProStudioMasters, HD Tracks or Pono will recreate the music that the artist created in the studio or at the live event.
Connect a NAS drive to the IDA-8 and your own unique digital library is now at your fingertips. Studio quality master recordings and the convenience of digital playback. Your music has never been more accessible.
For wireless convenience, you can connect an optional bluetooth module and connect your iPhone or iPad music to the IDA-8. For more traditional sources the IDA-8 can accept RCA jacks from your CD, DVD or Blu-ray player.
Connect a pair of speakers with the option of a dedicated subwoofer and the IDA-8 is capable of recreating everything from the deepest bass notes to soaring highs with authority and crystalline purity.
The Sound
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 complimented 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. 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 listen will convince you that the IDA-8’s performance and sophisticated styling are rarely duplicated at any price point.
The end result is that your music is perfectly reproduced and you will hear the music the way your favorite artists recorded it. The NuPrime IDA-8 faithfully recreates the music. It brings you closer to the live event than you have ever experienced before.
