IA-9X
US$ 1,299.00
NuPrime’s IA-9X is an integrated amplifier designed to work well in an analogue audio system. It combines two cutting-edge technologies – NuPrime ODC and Harmonic Generation circuits – to offer adjustable sonic characteristics. This makes it perfect for either studio monitoring or relaxing music listening.
The IA-9X offers the unique ability to customize its sound characteristics to suit your musical preferences.
- NuPrime Only Distortion Cancellation (ODC) circuit for ultra-low distortion for neutral and detailed sound.
- Harmonic generation circuit (utilizing Class A transistors) for slightly warm, end-rhyme, and rich sound similar to that of a vacuum tube amplifier.
A toggle switch that allows you to select only ODC circuit or ODC with natural harmonics. In Ultra- Low Distortion mode, it is typically suitable for studio monitoring or music with many dynamics, such as Rock & Roll. Alternatively, you can increase natural harmonics when relaxing and listening to more vocal or classical music.
The ODC class D PWM module include two NuPrime’s new ultra-low distortion amplifier modules (THD=0.0014%) composed of MUSES8820 op-amp in a new delta sigma circuit. It has excellent ultra-low distortion and high driving force characteristics.
NuPrime IA-9X pre-amp includes a MM phono input. The input and output use a special audio Relay Switch, which has the lowest interference and highly accurate transmission, to switch the source.
The phono input has a variety of settings for input resistors and capacitors to match different MM cartridges. PRA-9X phono amplifier is a 2-stage RIAA amplifier that utilises NJR MUSES8820 audio quality op-amp to provide an accurate RIAA curve and low distortion at high amplification and performance.

NuPrime IA-9X review by HiFi Class
The NuPrime IA-9X is an advanced integrated amplifier designed with Class D technology, featuring the innovative Only Distortion Cancellation (ODC) circuit. This circuit significantly reduces distortion and enhances sound quality, offering both superior microdynamics and bass impact in its “fo” setting, and greater homogeneity and depth in the “2fo” setting. The IA-9X maintains a neutral tonal balance with minimal coloration, making it versatile for various music genres. It excels in bass control, midrange richness, and clear high frequencies, providing a smooth and coherent sound transition. Additionally, its precise imaging and expansive soundstage construction further enhance its appeal, ensuring an engaging and realistic listening experience.
IA-9X review by John Ransley
With almost every other amplifier design, the sonic character you get is effectively set. Maybe you have old fashioned tone adjustment or switching for speaker impedance, but this doesn’t fundamentally change anything and often is a step backwards. The IA-9X has a second circuit which works in tandem with ODC – the Harmonic Generation Circuit utilising Class A transistors for a warmer, richer sound similar to that of a vacuum tube amplifier.
