Power amplifiers stereo — Vitus Audio SS-025

The SS-025 is a stereo power amplifier from Vitus Audio, sharing the SS-family's remarkably low output impedance with a modest power consumption relative to its output. The SS-025 brings Vitus's uncompromising Danish engineering to dedicated stereo power amplification.

Key specs that matter

Input sensitivity is 700mV, with input impedance at 10,000 ohms on both connections. Output impedance is a remarkably low 0.075 ohms single-ended. 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 under 0.01% at 100% global feedback. Maximum power consumption is a modest 150W relative to the substantial output power. At 135 x 435 x 436mm and 37kg, the SS-025 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.
