Know before you buy
The Harmonic Generation circuit introduces subtle, tube-like characteristics to the signal, adding warmth and richness to vocals and classical recordings. You can toggle this feature off to return to the amplifier's native, ultra-low distortion ODC mode for a more neutral and transparent sound.
Yes, the IA-9X features a highly flexible MM phono stage. You can manually adjust the input capacitance (100pF, 220pF, or 320pF) and input resistance (32K, 47K, or 100K ohms) to ensure optimal performance with your specific cartridge.
No, the NuPrime IA-9X is a purely analog integrated amplifier and does not include an internal digital-to-analog converter. You will need to use an external DAC if you intend to connect digital sources like streamers or CD players.
With 90W RMS into 8 ohms and 145W into 4 ohms, the IA-9X provides ample power for most bookshelf and medium-sized floor-standing speakers. Its high-current design ensures stability even when driving speakers with lower impedance loads.
No, the NuPrime IA-9X does not include a remote control. All volume adjustments and source switching are performed directly on the unit via its precise digital control interface.
The IA-9X is designed as an integrated amplifier. While it features various analog inputs and outputs, it is not bridgeable and is intended to function as the primary hub for your stereo system rather than as a dedicated power amplifier.
