Pioneer A-UK3II
¥ 45,000 (released in 1997)
Commentary
This is a pre-main amplifier that inherits the design philosophy of A-UK3 with simple and straight design and further refines the sound quality.
It omits all the attached functions and does not include tone control, balance control, or headphone jacks.
This simplifies result, the signal path and circuit layout are simplified and higher purity sound is sought.
Equipped with a wide-range linear circuit, it acquires stable driving power over a wide range.
Speaker terminal compatible with banana plug is adopted.
An inlet type power cord is used, and a 3-core cable with ground is used.
