The new class-A stereo power amplifier, A-48 is the replacement of A-47, and Accuphase has developed this new power amp for the first time in 4 years.
A-48 improves the low-noise characteristics with applying the discrete amps in signal input section equivalent to A-75. Also A-48 achieves the high output and constant voltage operation characteristic with the power amplifier configuration equivalent to A-75.
Super high damping factor is another important feature, this enables A-48 to easily drive any loud-speakers all over the world.
