Power amplifiers stereo — Constellation Audio Inspiration 2 Stereo Amplifier

The Inspiration 2 Stereo Amplifier is a stereo power amplifier from Constellation Audio, sitting within the brand's more accessible Inspiration series, built with an exceptional signal-to-noise ratio and exceptionally low output impedance. The Inspiration 2 Stereo Amplifier brings Constellation Audio's considered engineering to a two-channel power amplification format.

Key specs that matter

Input sensitivity is 15,000mV. Output impedance is an exceptionally low 0.1 ohms single-ended. Output power is 240W into 8 ohms, rising to 420W into 4 ohms. Gain is 25.2dBu. Frequency response spans 10Hz to 80,000Hz within plus-or-minus 3dB. Signal-to-noise ratio reaches an exceptional 125dB, with a remarkable damping factor of 80. At 432 x 216 x 483mm and 19.5kg, the Inspiration 2 Stereo Amplifier maintains a manageable stereo amplifier chassis for its considerable output capability.

Sound and use context

Expect exceptionally clean, powerful amplification reflecting the extraordinary 125dB signal-to-noise figure combined with the exceptionally low 0.1-ohm output impedance, consistent with Constellation Audio's broader considered engineering standards.

Pairing

The substantial 240/420W output combined with the low output impedance suits a wide range of loudspeaker impedances directly.

Alternatives

Constellation Audio's own Revelation 2 Stereo Amplifier offers a more accomplished alternative within the same broader amplifier catalogue for buyers wanting even greater output.
