The RI-101 MK.II is an integrated amplifier with built-in DAC from Vitus Audio, built with comprehensive three-plus-two input connectivity and an exceptionally wide bandwidth. The RI-101 MK.II brings Vitus's considered engineering to a substantial integrated chassis with digital conversion built in.
Key specs that matter
Three balanced XLR inputs and two single-ended inputs are provided, alongside the built-in DAC. Input sensitivity is 2,000mV, with input impedance at 16,000 ohms on both connections. Output impedance is 33 ohms balanced. Output power is 300W into 8 ohms, rising to 600W into 4 ohms. Frequency response extends up to an exceptionally wide 800,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 100dB, with total harmonic distortion plus noise at 0.04%. At 182 x 435 x 470mm and 38kg, the RI-101 MK.II represents a serious integrated amplifier commitment reflecting Vitus's considered Danish engineering standards.
Sound and use context
Expect extraordinary dynamic authority reflecting the substantial 600W-into-4-ohms output combined with the exceptionally wide bandwidth, consistent with Vitus's broader uncompromising engineering philosophy.
Pairing
The built-in DAC covers digital sources directly without needing a separate outboard converter.
Alternatives
Other manufacturers' comparable flagship-tier integrated amplifiers offer alternatives for buyers wanting to compare features at a similar price point.
