Nakamichi TA-20
¥ 85,000 (around 1989)
Commentary
A receiver that shares the basic configuration with the TA-30 and omits the visual function.
Uses a STASIS power amplifier based on a license from Threshold.
In addition, a multi-regulated power supply that blocks inter-stage interference and an isolated ground system that separates the delicate preamp section from other stages and keeps the ground potential constant at all times are adopted.
It is equipped with system remote control by two remote controls and variable loudness for natural listening compensation.
Two types of remote controls are included.
