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.
