Nakamichi TA-20
85,000yen(around the 1989 time)

The receiver which omitted the visual functionality while sharing TA-30 and a basic stream composition.

The STASIS power amplifier based on the concession from a threshold level company is adopted.
Moreover, the isolated rate grand scheme which separates the multi-regurated power supply and the delicate preamplifier part which intercept the cross interferencee between stages from other stages, and always keeps grand potential constant is adopted.

The system remote control by two sets of remote control, the variable loudness which can perform a natural auditory sensation weighting, etc. are carried.
