HiFi ROSE

Каталожен №:

The RS520 is an advanced, high-performance integrated amplifier and network streamer combo packing the main functions of existing all-in-one streamers into a single component with a powerful output of 200 watts per channel. 

The DAC and amplifier module incorporates the ES9038PRO DAC used in the HiFi ROSE flagship RS150B and Class AD amplifier module developed using the new GaN FET material and already featured in the exceptionally innovative high-end RA180 integrated amplifier used.

Integral aluminum housing

The product combines the key features of existing all-in-one streamers into one device, based on the design know-how and features that HiFi-ROSE has accumulated over many years. Manufactured with liberal use of high-strength 6000-class aluminum, the RS520's body is manufactured using an all-in-one process, with four sides produced as one piece. This manufacturing process is the ideal way to fundamentally block vibrations that can occur between individual parts, significantly reducing microphonic effects that can degrade sound quality.

12.6 inch wide LCD touch screen

The high standard of HiFi ROSE is also emphasized by the generous multi-touch LCD screen with a wide viewing angle. With a size of 309 x 82.9 mm and an LCD panel with a resolution of 1920*515, the operation of the RS520 is smooth and child's play.

ES9038PRO DAC

The RS520 features the ES9038PRO, ESS Technology's flagship DAC chip. This converter chip has an extremely low total harmonic distortion (THD+N) of -122dB and a dynamic range (DNR) of 140dB, making it arguably the best DAC chip in the industry today. The maximum sampling frequency and bit rate is PCM 768kHz/32bit, and DSD is supported up to DSD512. The ES9038PRO significantly reduces software implementation time compared to previous generations of converters, and is also equipped with ESS technology's exclusive jitter canceller, which ensures exceptional clock stability.

GaN based class AD amplifier

In order to design a perfect Class D amplifier, switching speed and accuracy must be guaranteed. However, due to the limitations of silicon FETs, linearity is weak compared to Class-A or Class-AB, limiting the ability to produce natural sounds. The RS520's Class AD amplifier uses a new GaN (gallium nitride) material FET to reduce "dead time" by 1/3 and maximize linearity. The result is a powerful 250W per channel of power with HiFi-ROSE's Class AD amplifier, which maximizes operating speed and accuracy to achieve the ideal Class D amplifier structure.

Discrete OPAMP

The discrete operational amplifier developed by HiFi ROSE is used in the current/voltage conversion, which is essential for current DACs. HiFi-ROSE focused on high open-loop gain and aimed for low open-loop distortion, low noise, low drift and low offset. Also, this op amp has a wide bandwidth and power supply range, necessary for high-quality analog audio amplification and adding depth to the sound. It reproduces the vividness of the deep bass and treble as in a live performance and makes the resonance of the inter-band connection very pleasant.

Field Effect Transistors are used in the input stage and the Class AB amplification method ensures consistent audio quality and minimizes heat build-up. Another pair of matched output transistors is combined with an emitter follower stage. This arrangement ensures high drive current and low output impedance, reducing the load on the voltage booster stage and strengthening the speaker's driving power.
