Network Transport

The Network Transport models are dedicated to delivering network audio playback at the highest quality by focusing purely on transport functionality. They can seamlessly integrate with external DACs through digital connectivity. Leveraging Rose’s hallmark wide-angle multi-touch screen and innovative ROSE OS, users can intuitively and conveniently stream not only music but also video content.

Network Streamer

The Network Streamer models are products that combine Transport and DAC into a single device, 

designed based on ROSE’s unique design expertise and platform accumulated over many years. 

ROSE OS, which offers various services along with the hallmark wide-angle multi-touch screen, 

provides an innovative listening experience.

Network All-In-One

The Network All-In-One models are integrated systems that include network transport, DAC, and

amplifier functionalities. With only speakers required, these products allow for the easy setup of a complete audio system with a single device. Utilizing ESS DAC chips and the Class AD amplifier

module, developed in-house and incorporating GaN FET achieves both innovative features and clear

high-quality sound simultaneously.

DAC

The DACs apply advanced technologies independently developed by ROSE to convert

digital signals input from the source with high purity, without degradation or distortion. The DAC lineup, crafted with ROSE's precise design and innovative technology, delivers the original sound information contained in audio sources with clarity and fidelity.

Amplifier

The Amplifier line-up consists of cutting-edge amplifiers that surpass the limitations of conventional amps by incorporating the latest innovative state-of-the-art technologies. Our proprietary Class AD maintains powerful damping power, the efficiency and power amplification characteristics of traditional Class D amplifiers, while delivering pure, natural, and vivid sound reminiscent of analog.

Accessory

Accessories that enhance the versatility of the ROSE product line.

ROSE Connect

ROSE Connect includes a Dedicated Remote Control Application that allows users to conveniently

control and smartly manage ROSE devices. The remote control application works on various

platforms including iPhone, iPad, Android devices, and PC.
