Optical Digital Reference Amplifier
Digital high performance.
Using Class AB amplification, the RS-A7 is huge on power and high-quality sound.
The amplifier can be digitally connected to the RS-A9 digital integrated amplifier using its optical digital inputs, to ensure that you maintain the utmost quality of the audio signal from the RS-D7RII tuner.
With no conversion to analogue necessary, you don’t lose any of the digital signal from the original music source, so the real expression of the music can be reproduced precisely.
Its high-performance circuit allows for a stable power supply. It has an enormous capacity for a sub or low channel output. This amplifier is the perfect answer to pure listening pleasure.
