The SS-103 is a stereo power amplifier from Vitus Audio, built with an exceptionally low output impedance and an extraordinarily wide bandwidth. The SS-103 brings Vitus Audio's most accomplished current engineering to two-channel power amplification.
Key specs that matter
Input sensitivity is 2,000mV, with input impedance at 10k ohms on both balanced and single-ended connections, and output impedance at an exceptionally low 0.075 ohms. Output power is 100W into 8 ohms, doubling cleanly to 200W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Frequency response extends to an extraordinary 800,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 100dB, with total harmonic distortion plus noise under 0.01% with full global feedback. At 310 x 435 x 601mm and a substantial 85kg, the SS-103 represents a serious stereo amplifier commitment reflecting Vitus Audio's uncompromising build standards.
Sound and use context
Expect exceptional control reflecting the exceptionally low sub-0.075-ohm output impedance combined with the clean power doubling into 4 ohms, suggesting genuine authority across a wide range of loudspeaker impedances.
Pairing
The clean power doubling into 4 ohms combined with the exceptionally low output impedance suits demanding, revealing loudspeaker loads directly, and Vitus Audio's own RL-102 preamplifier shares the brand's coherent engineering philosophy.
Alternatives
Vitus Audio's broader amplifier catalogue offers alternatives for buyers wanting a different output level.
