About the RI100
The Vitus Audio RI-100 is a powerful integrated amplifier from the Reference Series, designed to deliver exceptional musicality and power at a more accessible price point compared to higher-end lines. It features 300W RMS output per channel into 8 ohms (600W into 4 ohms), with options for phono stage, DAC (USB, RCA, XLR, Toslink, up to 2x DSD), and headphone amplifier modules. Inputs include 3x balanced XLR and 2x unbalanced RCA (one configurable for phono). It offers balanced XLR pre-outs for bi-amping or subwoofers. Known for its natural sound, grip, and fluidity, it uses a relay-based volume control, EI transformer, and separate power supplies per channel with twelve 10,000uF capacitors each. The RI-100 was released around 2011, replaced by RI-101 in 2017, and is no longer manufactured, though upgrades and service are available.
