Hifi Rose RA180 Integrated Amplifier

The Hifi Rose RA180 Integrated Amplifier is a state-of-the-art integrated amplifier using the latest innovative technologies. Power damping and dead times were reduced to 1/10th or less. Linearity was dramatically improved to create a near-perfect sound that transcends there 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 by HiFi ROSE has dramatically improved the problems of the existing Class D by applying innovative new materials.Class D amplifiers have a topology that theoretically p
