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.

An EASY 5 star performance

I live in the Great White North, far far away from ANYONE who makes the NuPrime IDA-8 amplifier so this is scout’s honour a bone fide 12 on 10 (if there could be such a revue score) on this monster of a little amp - no exaggeration, I didn’t think it would be THIS good - but THIS good it IS. If you’re sittin’ on the fence about trying one out . . . do so no longer. You’ll love it and won’t believe that so much could come out of such a modest sized enclosure. Happy listening!

Brilliant amplifier, don't let the size of the package fool you.

This is a long overdue review as I purchased this in Mar 2018. Easily drives my 6 ohm KEF Q50 floor standers and also sounds great with my Definitive Technology Pro Monitors paired with a Von Schweikert Audio VS-1 sub-woofer. Minimalist look but big sound , loads of dynamics, smooth highs and neutral sounding just the way I like it. Bluetooth streaming through the included dongle is surprisingly high quality. Purchased after discussing with Aamir and would definitely recommend doing business with him. I have not experienced any of the glitches mentioned by another reviewer, this thing is quiet, no sound turning on or off or while switching inputs. Great bang for the buck and i highly doubt i will find anything comparable sounding in the price could have done with another output or two but other than that its just perfect.

Brilliant integrated amplifier

I am using this amplifier with Klipsch RP600M speakers. As you may know Klipsch speakers are voiced on the forward/bright side of neutral, I was afraid the combination would sound bright and harsh, but I was wrong. The match is perfect. Loads of dynamics, live sound, very transparent amplifier. Does not have any competition at this price point and I think you have to spend a LOT more to get better. The DAC inside is very good as well, I am using it with an Allo USBridge as a Roon endpoint and it works flawlessly. I will upgrade soon to Klipsch Forte 3 and I plan to keep this amp, it's that good.

Incredible package in a single compact and stylish box

After spending many hours researching and trying a few integrated amps in the lower price range I realized that I needed something more powerful to drive my KEF-350 bookshelf speakers. Unfortunately powerful meant either a lot more expensive or lesser quality sound at higher volume. I was also hoping for smaller footprint, preferably minimalistic and stylish look and good quality DAC inside. After discussing my situation with Amir at Summit Hi-Fi, he recommended IDA-8. A couple of hours of research later I decided to give it a try. This little beast looks gorgeous and sounds incredible no matter how much you crank up the volume. It instantly made me feel that my setup was now complete and after a few weeks of using it I can't imagine switching to any of the cheaper amps I tried before it. There is only one thing I would've preferred if IDA-8 had and that's automatic reconnection to bluetooth on start. However the bluetooth module is external and I can replace it over time without having to change the amp. Since my music source is my computer I imagine there is also a software solution that can resolve this problem. In any case this issue was too small to affect my overall impression of the amp. Buying it from Summit Hi-Fi was also a flawless experience since Amir was always ready to answer any question or concern I had.
