RS250 is a model for audiophile with high-performance DAC and linear power in the RS201A, which was popular with its new design. 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 output 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.
