High-end hybrid integrated amplifier with valve pre-stage and Bluetooth® aptX™

The Magnat RV 4 hybrid amplifier combines audiophile sound demands and high performance in a perfect way: The combination of the valve pre-stage and transistor output stage ensures the coveted ´warm´ analogue sound characteristics with high output power at the same time for the best possible dynamics. RV 4 owners have the choice between numerous analogue inputs, including MM and MC, but also have the option of coaxial and optical digital access. The fact that the high-end Burr-Brown converter is also used for the Bluetooth 4.0 input with aptX is a further highlight. This high-end stereo amplifier thus combines feel and ease of use with the highest audiophile demands of both the analogue and the digital world.

What do trade magazines say about this product?

Exceptional hybrid concept

The audiophile heart of the Magnat RV 4 beats loudly and clearly in the pre-amp stage. Two high-quality, specially selected tubes produced in Russia are featured here. In this way, the Magnat engineers guarantee that the RV 4 delivers the warm tube sound so highly regarded among hi-fi fans. The necessary performance, with 150 watts RMS power output, is generated by the power amp with the help of high-quality Japanese transistors manufactured by Sanken.

Nostalgia meets wireless

With its wide variety of digital connection possibilities, the RV 4 delights both the purist vinyl enthusiast and the modern streaming fan. The integrated phono pre-amp has separate inputs for MM and MC systems, offering the possibility to enjoy your beloved record collection in the very best quality. But audiophile streaming fans are also catered for on account of the amplifier featuring a particularly high-quality Bluetooth module, including aptX.

Stylish, distinctive design

The audiophile tubes glow in warm orange, with the heat sink giving the high-end amplifier an individual appearance. The organic LED display provides information about the current volume and source selection status. The overall high-quality impression of the high-end amplifier is rounded off by an all-metal enclosure with an 8 mm front panel and the solid aluminium controls.
