The Vitus Audio RI-101 Mk.II is an integrated amplifier that sets a new standard in sound reproduction for its price range, embodying three key qualities: power, precision, and emotion. Designed as the first product in the Reference Series, it represents the ideal entry point into the world of Vitus Audio, featuring a minimal and refined design that easily integrates into any audio system, with the possibility to expand with other components from the same series, thus becoming the beating heart of the setup for many years.

The amplifier offers three balanced XLR inputs and two unbalanced RCA inputs, with the option of an additional DAC board that includes streaming capabilities via Ethernet input, an S/PDIF RCA input, and an AES XLR input. This versatility combines with a power output of 300 watts per channel at 8 ohms and 600 watts at 4 ohms, ensuring the ability to drive even demanding speakers.

In this updated version, the RI-101 Mk.II further enhances resolution and sound depth thanks to a new input and preamplifier section, which drastically lowers the noise floor. The volume control benefits from high-precision technology derived from the SL-103 and MP-L201 models, offering even more accurate and smooth control.

Regarding connectivity, the optional DAC/Streaming module supports major services such as Mconnect, UPNP/DLNA, Tidal Connect, Spotify Connect, V-tuner, Qobuz, and is certified as a Roon Ready endpoint, providing full integration with the Roon software for advanced management and top-quality playback. It is important to note that to function with Roon, the RI-101 Mk.II requires an external Roon Core, which acts as the central server for music management and streaming.
