IDA-16 – Digital Integrated Amplifier

IDA-16 – Digital Integrated Amplifier


Following a long tradition of world-renown audio excellence, the NuPrime IDA-16 combines leading-edge audio technology with unprecedented innovation, style, and value. As the world’s first fully integrated digital amplifier offering 384K & DSD decoding (2.8MHz, 5.6MHz, 11.2MHz), from its digital or analogue inputs to its 200-W per channel speaker outputs it delivers the purest, most natural sound that modern audio technology can provide, whilst also providing the widest support for the latest High-Resolution music formats.

Starting with complete integration of all necessary stages within one chassis, the IDA-16 design inherently ensures the shortest possible signal path thereby resulting in vanishing levels of noise and distortion to create a jet-black backdrop upon which your recordings literally unfold before your ears.

The deafening silence behind the IDA-16 is further augmented by the innovative volume control; a feature based upon advanced, thin-film switched-resistor technology that places only a single resistor in the signal path at any volume setting. Volume adjustment is conveniently achieved in 99 precise, 0.5dB increments and is further complimented by providing individually adjustable volume settings for each input. As such, precise level matching of the various sources within a personal home audio system becomes a breeze and makes comparison between them equally so.

The NuPrime amplifier circuit takes Class-D technology to the next level by utilising a “self-oscillating circuit to generate pulse width modulation”. The amplifier switches on and off at a frequency of 600kHz, well beyond the 44.1kHz sampling rate of redbook CD. Most Class-D amplifiers switch at 300kHz or lower. Completing the ensemble is NuPrime’s proprietary variable frequency Switch-Mode Power Supply (SMPS) technology. The IDA-16’s innovative supply and its Cross-Matrix Array (CMA) capacitor bank are capable – upon demand – of supplying extremely high current to the amplifier’s output stages which allow the IDA-16 to deliver thundering, authoritative bass. The result is unprecedented transient speed and an almost shocking level of dynamic impact that renders percussive instruments as though they were suddenly attacking outward from beyond the blackest depths of a phantom stage.

Such highly responsive behaviour achieves extremely low Total Harmonic Distortion + Noise (THD+N) levels of less than 0.004% while attaining a maximum system efficiency of up to 93%. Adding the IDA-16’s stratospheric frequency response up to 80 kHz, and now mere vocals are transformed nigh unto emotional experiences while the upper registers of instruments become the shimmering highlights of a live performance. In all, its crystalline transparency, holographic imaging and fatigue-free sound will allow you to relax and experience the music as it was meant to be… forgetting the IDA-16 is even there.

When the music stops and the lights rise, the IDA-16’s beautiful contemporary design aesthetic ensures the product will always be proudly displayed in any personal home audio system. The IDA-16 can be in a place of prominence within your room thanks to its sleek, low profile chassis and understated elegance.

“…when you consider the NuPrime IDA-16 has an advanced DAC built in, which will play virtually any digital recording available today, it’ s an even better value. Of course, if it didn’ t sound good, it wouldn’ t be a good value, no matter how low the price was, but it sounds excellent…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 in full here)
“…This quietness was a particular advantage when I listened at low volume levels, something I usually find uninvolving. Not through the IDA-16 — my music was just as captivating as at high volumes. Against the NuPrime’ s jet-black backgrounds, all of the dynamics of my recordings were present at all volume levels, making the IDA-16 one of the few amps I have enjoyed for late-night listening… IDA-16 is an exemplary integrated amp-DAC with rock-solid imaging, transparent sound, and tight control of bass…”, – Vince Hanada, SoundStage Network (read in full here)
