The C55 is a stereo power amplifier from Hegel, designed with a very high damping factor. It is intended for systems that use a separate preamplifier.

Key specs that matter

Output is 150 W per channel into 8 ohms, doubling to 300 W into 4 ohms. Gain is 29 dB and the rated bandwidth extends from 5 Hz to 100 kHz. Signal-to-noise ratio exceeds 100 dB, distortion stays under 0.01% and the damping factor is above 2000. The chassis measures 482 x 132 x 520 mm and weighs 37.5 kg.

Engineering and use context

The C55 has no preamplifier section of its own, so a separate preamplifier sets the volume and handles source selection.

Pairing

Because the power doubles into 4 ohms, the C55 suits demanding or low-sensitivity loudspeakers.

Alternatives

The Hegel C54 is another stereo power amplifier in the Hegel range.
