Power amplifiers mono — Constellation Audio Inspiration 2 Mono Amplifier

The Inspiration 2 Mono Amplifier is an accomplished monoblock power amplifier from Constellation Audio, a well-established American manufacturer known for uncompromising, high-end electronics engineering, built with a remarkably low output impedance. The Inspiration 2 Mono Amplifier brings Constellation's considered engineering to dedicated monoblock power amplification.

Key specs that matter

Input sensitivity is a substantial 17,800mV. Output impedance is a remarkably low 0.1 ohms single-ended. Output power is a substantial 500W into 8 ohms, rising to 1,000W into 4 ohms. Gain is 25.2dBu. Frequency response spans a wide 10Hz to 80,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an exceptional 125dB, with damping factor at 80. At 432 x 216 x 483mm and 19.5kg, the Inspiration 2 Mono Amplifier maintains a manageable monoblock chassis given its substantial output power.

Sound and use context

Expect exceptionally clean amplification reflecting the exceptional 125dB signal-to-noise figure combined with the remarkably low output impedance, consistent with Constellation's broader uncompromising American engineering philosophy.

Pairing

As a monoblock, two units are needed for a stereo pair, and the substantial 1,000W-into-4-ohms output handles demanding loudspeaker loads.

Alternatives

Constellation's own Performance 2 Monoblock offers a considerably more powerful alternative within the same broader catalogue.
