Усилители мощности моно — Extraudio XP-A2000

The XP-A2000 is a mono power amplifier from Extraudio, built with an exceptionally high signal-to-noise figure and damping factor. Extraudio is a comparatively specialist manufacturer whose catalogue emphasises extreme measured performance figures, and this monoblock's specification places it among the more ambitious designs compared elsewhere in this batch.

Key specs that matter

Input impedance is 7200 ohms balanced and 3600 ohms single-ended. Rated output is 1500 W into 8 ohms, rising to 2400 W into 4 ohms, an exceptionally high figure that places this amplifier among the most powerful monoblocks available from any manufacturer. Gain is 28 dBu. Rated bandwidth is 2 Hz to 110 kHz. Signal-to-noise is specified at 160 dB, an extraordinarily high figure that, if accurate under real operating conditions, would place this among the quietest amplifiers ever measured. Distortion is 0.003%. Maximum power consumption is 1500 W. Damping factor exceeds 1000. At 440 x 120 x 400 mm and 18 kg it is comparatively light given its exceptional rated output, a detail worth confirming directly with the manufacturer given how unusual that combination is.

Sound and use context

Expect an extremely high-output, high-damping-factor presentation, with the exceptional signal-to-noise figure suggesting a very quiet noise floor at any output level - buyers should treat headline figures this extreme with appropriate scrutiny and seek independent verification where possible before assuming parity with more conservatively rated competitors.

Pairing

The 7200 ohm balanced input impedance works with any modern preamplifier.

Alternatives

Extraudio's broader amplifier range offers alternatives at different power levels for a listener comparing the brand's monoblock options, worth researching directly given the brand's less widely established reputation compared with more mainstream manufacturers. Extraudio remains a considerably less internationally recognised name than most other brands compared in this batch, so seeking independent, third-party measurements to verify these headline figures is a worthwhile precaution before committing to a purchase at this scale. The relatively light 18 kg weight for an amplifier claiming this level of output is itself worth clarifying directly with a dealer, since most designs capable of sustained multi-kilowatt output tend to carry substantially heavier transformers and heatsinks.
