Power amplifiers stereo — Constellation Audio Performance 2 Stereo Amplifier

The Performance 2 Stereo Amplifier is a flagship power amplifier from Constellation Audio, built with the brand's revolutionary C-SMPS switch-mode power supply and Balanced Bridged circuit configuration. Constellation Audio describes this as a pinnacle achievement, refining the proven circuits and core design philosophy that define the brand's overall approach, eclipsing the sonic results of both its direct predecessor and even the outgoing Reference series.

Key specs that matter

Rated output is a substantial 600 watts per channel into 8 ohms, rising to 1,125 watts per channel into 4 ohms. The C-SMPS power supply, which Constellation describes as the best power supply it has ever created, delivers ultra-clean, consistent power far surpassing what a traditional transformer-based design achieves, contributing to a low noise floor and high dynamic range. The Balanced Bridged configuration is a distinctive approach - rather than the conventional balanced-amplifier method of using N-type transistors for the positive signal half and P-type transistors for the negative half, Constellation's design uses only N-type transistors for both halves, so both signal paths pass through identical circuitry, preserving even the softest musical details with matched fidelity. A Constellation Direct XLR input removes an entire amplification stage from the signal path for reduced complexity and even greater musicality. Large analogue meters, a first for this series, provide an instantaneous glimpse of power output and lend the flagship a signature appearance.

Sound and use context

Expect a sense of realism that borders on a live event, with Balanced Bridge technology ensuring no overload even at reference volumes - listeners can expect peaks around 112dBA in-room without acoustic artifacts, and Constellation states this amplifier is capable of driving any loudspeaker to its full potential regardless of impedance or sensitivity demands.

Pairing

The Constellation Direct XLR input pairs specifically well with the matching Performance 2 Preamplifier, together forming what Constellation considers the nucleus of its most sophisticated and satisfying complete audio system.

Alternatives

Constellation Audio's Performance 2 Monoblock Amplifier sits above this stereo model, delivering 1,200 watts into 8 ohms and 2,000 watts into 4 ohms per unit, worth the further investment for buyers with insensitive speakers or the largest listening rooms if this stereo amplifier's already substantial 600/1,125 watt output proves insufficient.
