The RA180 is a state-of-the-art integrated amplifier using the latest innovative technologies.
Power damping and dead times were reduced to 1/10 or less. Linearity was dramatically
improved to create a near-perfect sound that transcends the boundaries between digital and analog.
Enjoy the pure sound of nature provided by the RA180.
New Concept Class AD Amplifier
The amplifier has developed from Class A to AB to Class D. Class AB was developed to
improve the high heat generation and low efficiency of A.
Class D has higher efficiency and higher output than AB, and also significantly improved
S/N and THD characteristics compared to A and AB.
However, the sound quality has been evaluated as inferior to A/AB due to the limitations of the digital circuit,
The GaN class AD amplifier developed b HiFi ROSE has dramaticallv improved the problems
of the existing Class D by applying innovative new materials.
