The RS520 just might be the highest value product in the HiFi Rose 2023 line-up. It is an all-in-one product featuring a built-in network player / streamer, DAC, and a powerful, 250 watt per channel integrated amplifier. It is equipped with the ES9038PRO DAC, the flagship DAC chip of ESS technology. The audio quality when streaming services like Qobuz has to be heard to be believed. The Class AD amplifier module is a newly developed GaN-FET design, and is significantly more musical than previous Class D designs. The Gan-FET topology is faster, more efficient, and even cooler-running than prior Class D designs. RS520 is a complete audio solution, an advanced all-in-one amplifier / network streamer that will satisfy even the most demanding music listeners.
Unchangeable Value
The design of the RS520 focused on values that did not change over time. A refined design that will not change over time and a bold ventilation hole for hear dissipation represent a gentleman with both functionality and enterprising appearance.
Integral Aluminum Housing
The housing of the RS520, which is made with generous use of high-durability 6000 class aluminum material. It is manufactured by an all-in-one process in which four sides are produced as one part. The all-in-one manufacturing process is the most ideal method to fundamentally block vibrations that may occur between separated parts. Significantly reducing noise waves that can affect sound quality.
12.6-Inch Wide LCD Touchscreen
Visible audio is emphasized using HiFi ROSE's spacious, wide-viewing-angle multi-touch LCD screen. With a size of 309*82.9 (mm) and a 1920*515 resolution LCD panel. You can enjoy a smooth and clear screen.
