Testimonials (on all Nuprime Integrated Amplifiers)

2016 Product of the Year Award – The Absolute Sound 

The NuPrime IDA-8 is a winner, and a force to be reckoned with in its category (and beyond it). It delivers substance and warmth with speed, resolution, and plenty of gusto—and does so from an astonishingly quiet background… A well-conceived Class A/Class D hybrid that doesn’t want for power or clarity, the IDA-8 ought to find itself on the audition short list of a wide range of hi-fi hobbyists, from newbies to more experienced audiophiles. I’m considering purchasing my review sample. Highly recommended!
 – Julie Mullins, The Absolute Sound

“From the very first listen, the IDA-8 elicits a big ‘wow’. Simply that the Nuprime IDA-8 is easily the best sounding amplifier we’ve ever heard under $2000 by a wide margin.

“I finally set up my bedroom system with the IDA-8 and the KEF LS50s with the new subwoofer. With the Bluetooth dongle the sound is pretty impressive. … It is pretty amazing what that amp can do for that money-that amp is easily the equal of some 2k amps I have heard. … The LS50s really continue to amaze and really benefit from the sub in the system.”
– Jeff K, VT (a happy IDA-8 owner)

Nuprime IDA-16, AFFORDABLE INTEGRATED AMPLIFIER OF THE YEAR (2015) – The Absolute Sound

“The NuPrime IDA-16 DAC/amplifier along with the KEF LS50 speakers made a system that, if you’ll pardon a tired reviewer cliché, punched far above its weight. So to return to the question left open in the first paragraph: Yes, the NuPrime IDA-16 DAC/amplifier can indeed be called a bargain. Highly recommended.”
– Vade Forrester, The Absolute Sound (read the review)

“The NuPrime IDA-16 Integrated Amplifier is an exemplary integrated amp-DAC with rock-solid imaging, transparent sound, and tight control of bass. It doesn’t impose a sonic signature on the sound — I was enthralled with every recording I played through it. There are similarly priced integrated-DACs out there, from Bel Canto and Wyred 4 Sound, among others, but none offers the IDA-16’s power or support of native DSD. I highly recommend that you give the NuPrime IDA-16 a listen if you’re in the market for a modern integrated-DAC.”
– Vince Hanada, soundstagenetwork.com (read the review)

“The NuPrime IDA 16 Integrated Amplifier delivers more sound quality, power and sophistication than any other DAC and amplifier combination, digital or analogue we’ve heard regardless of cost. This isn’t a statement we make without a lot of consideration and listening. NuPrime has delivered a remarkable product at a better-than-fair price that you’ll be thrilled to own, both now and for years to come.”

NuPrime IDA 8 Integrated Amplifier 12

 

Overview

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.

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 audition will convince you that the IDA-8’s performance and sophisticated styling are rarely duplicated at any price point.
