HiFi Rose RS 250 / RS250A Streamer

RS250A with built-in ESS flagship DAC (ES9028PRO) provides low-noise, low-distortion ultra-high-resolution sound and rich analog density through proprietary processing that supports PCM 32bit/768KHz and Native DSD512 (22.5792Mhz).

The wide LCD and multi-touch provide a new experience as an audio device and add perfection to those seeking simplicity. The harmonious design of the high-quality aluminum body emphasizing the same edge as the previous product and the cool wide viewing angle touchscreen placed on the front side makes your music space stand out even more. The rotary-type power and volume switches in consideration of visual effect and practicality pursue ROSE's own delicacy.

Acoustic engineers and audio craftsmen with 30 years of experience tune the device to deliver the original impression and intention of high-quality sound. It clearly expresses the entire range, from the magnificent and rich bass to the delicate and elegant highs.

The linear power supply provides a clean and reliable power supply to the CPU
and audio outout circuits Fully linear power supply and shielding are applied, and noise that may be transmitted to sensitive DAC is blocked for the best possible sound reproduction.

Aluminum is processed as an integral unit to maximize thermal efficiency, and by minimizing the assembly area, vibration that can affect sound quality is greatly
reduced, creating a profound and ideal sense of space.

MQA is the only technology capable of seamlessly streaming the original master
sound in low capacity. The device supports the top-level MQA Full Decoder feature, so you can play studio mastering quality sound.
