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.
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.
