Nakamichi IA-2

Commentary

Pre-main amplifier of the selected component series developed as a Limited Edition limited to 300 units.

The preamplifier section and power amplifier section use Nakamichi's original harmonic time alignment amplifier circuit.
This circuit focuses on the phase shift between a music signal and its harmonic distortion, which is a harmful effect of NFB, which is widely used to improve amplifier characteristics. It uses a wide bandwidth, low gain, and open-loop design to keep the amount of NFB in the audio band constant, and to minimize the amount of NFB itself. This circuit combines techniques correctly adjust the phase of the fundamental sound and distortion components.

Multi-regulated power supply and isolated ground system are adopted to prevent power source interference and noise contamination to signal system.

A fully discrete configuration is used for the line amplifier section.

Equipped with a phono equalizer amplifier.

Wireless remote control is included.
This remote control can control the whole system when connected to Nakamichi's CD player or deck.
