Constellation Revelation 2 Power Amplifier
Revealing Every Detail
Our Revelation 2 Stereo and Mono Amplifiers distill the power and passion of our original amplifiers into a more compact chassis. And now we’ve added C-SMPS, the best amplifier power supply ever created.
The Revelation 2 amplifiers use our Balanced Bridged technology: a musical, single-ended amplifier module. To achieve the desired output, we add modules, rather than increasing circuit complexity. The result? Ample power to drive any speaker, with the subtlety of a small amplifier.
The Input Stage
The Revelation 2 Stereo and Mono Amplifiers use the same Line Stage Gain Module input stage found in our top amplifiers. Hand-matched, low-noise transistors combine with a servo circuit that corrects for any inconsistencies in the signal balance.
The Revelation 2 amplifiers’ Constellation Link interface connects to Constellation amplifiers to take one amplification stage out of the signal path-less complexity, more musicality.
The Circuit
The Revelation 2 Stereo and Mono Amplifiers employ a balanced configuration, with separate amplifier circuits for the positive and negative halves of the audio signal. Other balanced amplifiers use N-type transistors for the positive half of the circuit and P-type transistors for the negative half. Our Balanced Bridged configuration uses only N-type transistors, so both signal halves pass through exactly the same circuitry-and even the softest musical details are preserved.
The Power Supply
Our Constellation Switched-Mode Power Supply (C-SMPS) rises above the century-old technologies that hinder the performance of traditional amplifiers, with noise more than 20 dB lower than a typical linear supply achieves.
Our Power Factor Correction (PFC) technology provides stable power at any AC supply voltage, anywhere in the world, with voltage and current always in phase no matter what the speaker load. It also boosts these amplifiers’ power over the previous version by 20 percent.
The Result
We like to think of the Revelation 2 amplifiers as distilled versions of our larger models, because the circuits and the core design philosophy are the same. In fact, they’re a perfect example of why our approach to amplification works so well. We didn’t have to redesign the amplifiers to make them smaller, we just reduced the number of modules and made the power supply a bit less overbuilt.
When you hear what the combination of our innovative audio circuits and revolutionary C-SMPS power supply achieves, we expect you’ll be as astonished as the reviewers and showgoers who experienced the debut of these designs. The Revelation 2 amplifiers may be smaller in stature, but their musicality and emotion are undiminished.

Munich High-End 2024: The Top, Top Fives!
The annual Munich High-End Show is the predominant audio event. This is still the show to attend if you want to know what’s new and what’s next in audio.
Prominent Magazine HiFi Plus tasked several reviewers at the show with coming up with their top five products at the event.
We consciously avoided getting our reviewers to share their recommendations. Rather than avoiding repeats, we wanted to show if there was consensus. Also, with such a large show, the risk of repeats was relatively low. In fact, just one brand was picked by more than one reviewer—Alan Sircom and Tom Martin selected Constellation Audio in their respective top fives.
This is Huge - where else can one compare the top amplifiers brands at one place and time?
