Three words that best describe the RI-101 Mk.II and a hint at the feelings this integrated amplifier will engender in the listener. This amp, the first product designed for our Reference Series and the entry point to the world of Vitus Audio, quite simply sets a new standard for sound reproduction at this price point.

Three words that best describe the RI-101 Mk.II and a hint at the feelings this integrated amplifier will engender in the listener. This amp, the first product designed for our Reference Series and the entry point to the world of Vitus Audio, quite simply sets a new standard for sound reproduction at this price point.
Our engineering team have created a component that raises the bar of solid state integrated amplifiers. With Vitus Audio’s signature minimal styling and the possibility of expansion with other components from the Reference Series, the RI-101 Mk.II will happily sit at the heart of your system for a lifetime.
The RI-101 Mk.II has three XLR (balanced), two RCA (unbalanced) inputs and can be specified with an optional DAC board offering a streamer (Ethernet) input, an S/PDIF (RCA) input and an AES (XLR) input. This is the workhorse at the heart of your system giving 300 W per channel to 8Ω speakers and 600 W at 4Ω.
In this iteration, experience enhanced resolution and blackness thanks to the updated input stage and pre-amplifier section. The noise floor is significantly lowered and the incorporation of the higher resolution volume control from our SL-103 and MP-L201 models offers you even greater control.
As Edgar Kramer, Editor-in-Chief at SoundStage Australia put it: “The Vitus Audio RI-101 is a stupendous sonic performer, excelling at the vividness and life of music… tight, punchy and detailed bass jumps from the mix while the RI-101 amplifier simply thinks, ‘Is this all you’ve got?’”
Connectivity with the optional DAC/Streaming module (2023 version)
The RI-101 Mk.II supports Mconnect, UPNP/DLNA, Tidal Connect, Spotify connect, V-tuner, Qobuz amongst others.
The RI-101 Mk.II is now also certified as a Roon Ready endpoint. Find out more on the Roon partner page.
Streaming with the Roon software
It’s important to note that while the RI-101 MK.II with the DAC/Streamer module is Roon Ready, it requires a separate Roon Core to function. The Roon Core acts as the central server that manages your music collection and streams audio to the RI-101 MK.II. This setup ensures a robust and high-quality audio experience, leveraging Roon’s advanced features and the RI-101 MK.II’s exceptional sound performance.
