HiFi Rose Silver Integrated Amplifier

Linearity dramatically improved to create a near-perfect sound

Power damping and dead times reduced to 1/10 or less

Transcends the boundaries between digital and analog

This amplifier has developed from Class A to Class 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 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 provides a perfect linear output at 0% distortion and 100% power efficiency. In order to achieve this, the switching action requires high speed and accuracy. However, previous products were weak compared to Class A/AB in the linearity aspect due to the limitations of silicon FET, which couldn't produce a smooth and natural sound. In the RA180, a new material, GaN FET, was used instead of Silicon FET to solve this problem. The dead time was dramatically improved to 1/10 or less, and a nearly perfect linear output was realized with a switching speed close to zero. This linearity goes beyond the Class D limits and produces a smooth and natural sound, like an analog amplifier.

The RA180 consists of two modules: one AMP module specialized for stable mid-bass and balance, and another specialized for smooth, high-pitched and and super tweeter areas. Each AMP modules supports 200 W (8 ohms) and can output up to 400 W per channel. When two independent modules are connected to a speaker's high and low frequencies separately, the driving force can be greatly improved without being affected by a counter electro-motive force. BTL mode combines two independent modules for rich, balanced sound.

Designed to Play Up to the Super Twitter Realm

The human hearing range has an upper limit of 15-20 kHz. So, is there no need for higher frequencies? Temporarily high trebles extend well beyond 20 kHz, even in harmonious sound. For example, trumpets have a frequency response that extends to 100 kHz, and 88.2 kHz to 192 kHz sources have a 40 kHz to 96 kHz frequency response. The RA180 is designed with a wide frequency response range so that even high resolution sound sources with an output range of 20 Hz to 50 kHz, 100 kHz at -3 dB, 200 kHz at -6 dB. Although this playability may be outside a person's hearing range, it faithfully reproduces a frequency range, which contributes to expressing a deep and wide sound field with the original sound.

The power supply that has been exclusively developed for the RA180 applies 4th generation SiC FET technology to provide high output with less heat. In addition, by using a self-developed PFC (Power Factor Circuit), it is designed not to be affected by sudden load fluctuations. The power supply device was developed to support a powerful damping factor of at least 200, and the high output of 1000 W is designed to produced powerful bass and soft treble.

The purpose of the PHONO amplifier provided by the RA180 is for the recording producer to accurately reproduce the original intention. It also reproduces the original sound as it is, which is the principle of HiFi Rose. It is designed to respond to a variety of vinyl records with low-mid bass turnover and high frequency roll off adjustment functions. Moving magnet and moving coil stages are provided with a simple switch selection and EQ values corresponding to curves from various record manufacturers are provided using parts with a 0.1% tolerance.

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, while linearity was dramatically improved to create a near-perfect sound that transcends the boundaries between digital and analog. Enjoy the sound of nature.
