Introduction
NuPrime's IA-9X is an integrated amplifier designed to work well in an analogue audio
system. It combines two innovative designs to give it adjustable sonic characteristics.
•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.
The IA-9X offers the unique ability to customize its sound characteristics to suit your
musical preferences. 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.
