Nuprime IA-9X integrated amplifier with MM phono preamplifier

Nuprime IA-9X integrated amplifier with MM phono preamplifier

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.
