Commentary
PRESTA series pre-main amplifier.
The power supply section uses a toroidal transformer with little leakage flux and excellent performance in vibration prevention.
Low-impedance volume is used to improve the SN ratio at general listening levels.
Equipped with a source direct switch, it is possible to bypass the tone control.
It comes with a remote control so you can control not only the main body but also the CD player, cassette deck and tuner in a centralized manner.
