Power amplifiers stereo — Anthem P5

The P5 is a substantial stereo power amplifier from Anthem, sitting above the MCA series with considerably greater output power and mass. The P5 represents Anthem's more ambitious current statement in power amplifier engineering.

Key specs that matter

Input sensitivity is 1,000mV. Input impedance is 22,000 ohms balanced or 18,000 ohms single-ended. Output power is a substantial 325W into 8 ohms, rising to 500W into 4 ohms - considerably more than the MCA series. Gain is 29dBu. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an exceptional 125dB, with total harmonic distortion plus noise at an exceptionally low 0.0007% at 100% global feedback. Maximum power consumption is a substantial 1,800W, with damping factor exceeding an extraordinary 600. At 238 x 490 x 572mm and a substantial 59kg, the P5 represents a serious power amplifier commitment reflecting Anthem's more accomplished current engineering.

Sound and use context

Expect exceptionally clean, authoritative amplification reflecting the exceptional 125dB signal-to-noise figure combined with the extraordinary over-600 damping factor, representing Anthem's more accomplished current engineering standards above the MCA series.

Pairing

The extraordinary over-600 damping factor combined with the substantial 500W-into-4-ohms output suits demanding loudspeaker loads with excellent bass control.
