Nuprime IA-9X black

Stereo Amplifier: NuPrime IA-9X

The NuPrime IA-9X is an integrated amplifier that showcases the power of modern audio technology. It stands out for its ultra-low distortion characteristics and strong driving capability, making it a top choice for audiophiles seeking a high-fidelity sound experience.

Sound Quality

The IA-9X is equipped with NuPrime’s unique Oscillation Distortion Cancellation (ODC) circuit, which ensures ultra-low distortion for neutral and detailed sound. This makes it ideal for studio monitoring or enjoying music with lots of dynamics, like Rock & Roll.

In addition to the ODC circuit, the IA-9X also features a harmonic generation circuit that uses Class A transistors. This circuit generates a slightly warm, rich sound with a harmonious decay, similar to that of a vacuum tube amplifier. This unique combination of circuits allows the IA-9X to offer a customizable sound experience tailored to the listener’s preferences.

Power and Precision

The IA-9X is a powerhouse, with an output of 90W RMS at 8Ω and 145W RMS at 4 Ohms. It can also deliver a peak power of 100W at 8Ω and 160W at 4 Ohms. This high output power, combined with the amplifier’s ultra-low distortion characteristics and strong driving force, ensures that the IA-9X can drive your speakers with precision and control.

Versatile Connectivity

The IA-9X offers a range of input options, including an MM phono input, two analog stereo RCA inputs, and an analog stereo XLR input. The phono input is particularly noteworthy, as it includes a variety of settings for input resistances and capacitors to match different MM cartridges. This makes the IA-9X an excellent choice for vinyl enthusiasts.

The amplifier also includes output options such as analog stereo RCA and XLR outputs, and a trigger input for controlling power on/off of multiple devices. This wide range of connectivity options makes the IA-9X a versatile addition to any audio setup.

Design Elements

The IA-9X is designed with an emphasis on superior audio performance. It includes specifically customized audio-grade capacitors and high-current bridge rectifiers, providing fast and dynamic driving force for speakers. The input and output use a special audio relay switch, which ensures low interference and highly accurate transmission.
