Power amplifiers stereo — Vitus Audio RS-101

The RS-101 is a stereo power amplifier from Vitus Audio, sharing the MP-S201's remarkably low output impedance with somewhat more modest, though still substantial, output power. The RS-101 brings Vitus's uncompromising Danish engineering to dedicated stereo power amplification.

Key specs that matter

Input sensitivity is 2,000mV, with input impedance at 10,000 ohms on both connections. Output impedance is a remarkably low 0.075 ohms single-ended. Output power is a substantial 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. Total harmonic distortion plus noise is under 0.01% at 100% global feedback. Maximum power consumption is a modest 90W. At 195 x 435 x 435mm and 42kg, the RS-101 represents a substantial power amplifier commitment reflecting Vitus's uncompromising engineering standards.

Sound and use context

Expect exceptionally clean, tightly controlled amplification reflecting the remarkably low output impedance, consistent with Vitus's broader uncompromising Danish engineering philosophy.

Pairing

The substantial 600W into 4 ohms output handles demanding loudspeaker loads with considerable headroom.

Alternatives

Vitus's own MP-S201 offers a considerably more powerful flagship-tier alternative within the same broader stereo power amplifier catalogue.
