Commentary
Based on the A-10X which is the final model of NEC's A-10 series pre-main amplifier, this pre-main amplifier was created by reviewing all parts.
Twin mono construction is used to minimize interference between the left and right channels.
A gold-plated twin crossbar contact relay is placed close to the input terminal and is used as an input selector to completely eliminate mutual interference between sections and parts.
A total of 120,000 μ F smoothing capacitor is mounted.
Natural granite is used for the top plate of the amplifier body, and while the appearance is refined, the excellent vibration resistant structure is realized by utilizing the property and weight of granite.
There are 5 kinds of natural granite, 2 kinds of front panel in black and champagne gold, and 2 types of wooden side panels, which can be combined according to preference.
