Constellation Revelation 2 Pre-Amplifier
Reveal the Details
The Revelation 2 Preamplifier distills the designs of our elite preamplifiers into a component practical for audiophiles who don’t require as many inputs.
Importantly, we’ve added C- SMPS, for cleaner, more consistent power than transformer-based power supplies can deliver. As in all of our preamplifiers, the Revelation 2 Preamplifier is based on our exclusive Line Stage Gain Module, which produces truly extraordinary depth and musicality.
Classic Circuitry
The Line Stage Gain Module is a big part of why Constellation components have won raves from so many reviewers over the last decade. The module incorporates fully balanced, mirror-imaged circuits made from hand-matched, low-noise transistors.
A unique servo circuit monitors the signal balance and corrects for any inconsistencies. Owners of Constellation amplifiers can feed the preamplifier output to the amplifier’s Constellation Link input, thus bypassing the amplifier’s input stage for even purer sound.
C-SMPS Power Supply
Our engineers spent years developing our Constellation Switched-Mode Power Supply (C-SMPS), because they knew that despite the engineering challenges, they’d eventually be able to deliver far better results than linear power supplies can achieve. The result is DC voltage more than 20 dB quieter, and the same predictably excellent results no matter what the AC wall voltage.
We further isolate the power supply from the sensitive preamp circuits by placing it in a separate enclosure, milled from aluminum slabs thick enough to block all interference.
True Dual Mono
We built the Revelation 2 Preamplifier in mirror-imaged halves, with the left channel on one side and right channel on the other. The inputs and outputs for left and right channels are also separated. Many dual-mono preamplifiers separate the circuit boards but bring the signals back together at the jack panel, thus reducing the benefit of the dual-mono design.
Simple, Elegant, Powerful
The Revelation 2 Preamplifier is as simple as it is sophisticated. We combine our innovative circuits and power supply with a digitally controlled resistor ladder, for the purest analog sound with precision no potentiometer can match. Volume and other functions are controlled through an LCD touchscreen with intuitive control buttons and indicators along the bottom, and an elegant, machined-aluminum remote control.
In this era when so many audiophiles find themselves using fewer source devices, the Revelation 2 Preamplifier is especially well-adapted. The same technology, the same circuits, and the same meticulous design and musicality of our most elite preamplifiers, are distilled into a more practical package.

Munich High-End Show: 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?
