The C54 is a stereo power amplifier from Hegel, sharing electrical specifications with the C53 while offering considerably greater chassis mass. The C54 brings Hegel's considered engineering to two-channel power amplification.
Key specs that matter
Output power is 150W into 8 ohms, doubling cleanly to 300W into 4 ohms, matching the C53. Gain is 29dBu. Frequency response spans an extraordinary 5Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 100dB, with total harmonic distortion plus noise at 0.01%, and a remarkable damping factor exceeding 2,000, all matching the C53. At 482 x 132 x 520mm and 33kg, the C54's considerably greater weight than the C53's 28.5kg reflects more serious internal transformer or heat-sinking componentry.
Sound and use context
Expect exceptional control combined with substantial power delivery matching the C53's electrical performance, with the considerably greater 33kg mass suggesting more serious internal engineering.
Pairing
The clean power doubling into 4 ohms combined with the exceptional damping factor suits demanding, revealing loudspeaker loads directly.
Alternatives
Hegel's own C53 offers a somewhat lighter alternative sharing identical electrical specifications within the same broader amplifier catalogue.
