Vitus Audio RI-101 MK2 Integrated Amplifier

Expression, Emotion, Finesse.

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.

Everything connected

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.

Finishing

The RI-101 Mk.II comes in Pure White, Jet Black and Warm Silver as standard. Titanium Orange, Dark Champagne and Titanium Grey are our most popular unique finishes.

The evolution of an icon

The story of our Reference Series RI-101 MkII integrated amplifier is
one of advancing technology driving an ever-more refined and versatile
performance.

After nine years of scintillating service, leaving in its wake a host
of industry awards, the RI-100 was succeeded by the RI-101. Apart from
identical power and output stages, the new amplifier enjoyed major
upgrades to the input stage resulting in a markedly lower noise level
with enhanced resolution.

While the changes brought the Reference model closer to its
Signature and Masterpiece equivalents, it was deemed by reviewers
to be “still its own beast”, creating for the listener an unique musical
experience.
“…a stupendous sonic performer, excelling at the
vividness and life of music while sustaining its tonal
beauty, midrange purity and exerting tight-fisted
control over its prodigious output.” Soundstage Australia

Externally, the most recent iteration of the concept, the Mk II,
retains the unmistakeable design stamp of our brand – cool, clean lines
and a minute attention to the fine details of finish.
However, the ‘inside story’ is another matter, and is even more
significant than the initial evolution from RI-100 to RI-101.

The amplifier is rated at 300w into 8ohms and is capable of driving
even the most demanding of loads with effortless ease and control.
With three balanced XLR inputs, two RCA inputs and a pair of
balanced outputs (the preamplifier section is fully balanced), there is
more than enough flexibility for future expansion. The binding posts
on the rear panel are extremely robust and will work well with any
speaker cables.

We offer an optional Streaming DAC Module, incorporating an
Ethernet socket that allows streaming from Tidal or Qobuz, as well as
Internet Radio. You can also stream music stored locally over a network
via UPnP.
“The RI-101 is incredibly quiet, with well-defined, pow
erful bass and a grain-free high end to match.
Vitus Audio is one of the few solid state amplifier
manufacturers that will not have you wishing for
vacuum tubes … For anyone wanting a world class
system without a rack full of gear, the RI-101 Mk II
is an excellent choice.” Tone magazine
