Power Amplifiers

Our Balanced Bridged topology uses only N-type output transistors, so the two halves of the audio signal are always perfectly balanced. In most fully balanced amplifiers, the schematics for the positive and negative halves of the amplifier circuit are mirrored, but one half uses N-type transistors and the other half uses P-type transistors. Thus, a perfectly balanced output can never be achieved.

Constellation Audio, the renowned luxury goods manufacturer of high performance solid-state electronics, is pleased to announce the introduction of the new Revelation Series of components at CES 2017. CEO Dr. Murali Murugasu challenged his dream team of designers and engineers to develop a new series of Constellation Audio components that could deliver the essence of our renowned Performance Series. The results are truly a Revelation.

Building on the successful introduction of the Centaur II stereo and mono amplifiers last year, and benefitting from the research and development used to create the Reference Series Hercules II amplifiers, this new amplifier satisfies the demand for a more powerful Performance Series amplifier. Products of the Constellation Audio “dream team,” the Centaur II 500 Stereo delivers outstanding audio performance across the entire musical range and regardless of the type of music.

The original Momentum Mono Amplifier was the first product designed and manufactured by the company and the latest version, the Momentum M400 MxV Mono amplifier elevates this iconic design to its greatest height. The Momentum M400 MxV models feature techniques and topologies initially developed and implemented in the Relentless Mono Amplifier. This fullest expression of the Momentum circuitry is reflected in the new model name, MxV. Those with a physics background will recognize that MxV or Mass times Velocity is the equation for Momentum. 

Dan D’Agostino has always had a relentless desire to better his own creations, no matter how flawless they may seem. The Relentless Monoblock amplifier is the latest manifestation of that passion, the result of Dan’s desire for an amplifier that maintains its harmonic integrity and expansive soundstage from 0 watts to 1,500 watts. An amplifier so powerful it can drive any speaker to its best possible performance, no matter how demanding the load it may present.

The Momentum S250 MvX stereo amplifier delivers the extraordinary sound quality of the Momentum M400 MvX monoblock in a more affordable stereo design. The circuit topology and construction of the stereo amplifier mirror those of the monoblock, using the same ultra-efficient copper heat sinks with venturi cooling, the same 1% metal-film resistors, the same 69 MHz output transistors and the same fully complementary balanced configuration. The result is audio fidelity equaled by no other amplifier—except, of course, the Momentum M400 MxV monoblock itself. The leading compliment to the Momentum S250 MvX Stereo is the Momentum HD Preamplifier, creating a harmony worthy of any aficionado.

THE PROGRESSION MONO DESIGN combines two normally exclusive traits—remarkable power output and exquisite musical finesse. Power is essential to realistic sound reproduction. The Progression mono amplifier is the largest and most powerful the company has made, delivering 500 watts into 8 ohms, doubling to 1,000 watts into 4 ohms and doubling again to 2,000 watts into 2 ohms. Of course, it will play loud, but it is speaker driver control that is the most important aspect of this awesome power capability.

The Progression Stereo Amplifier extends the Progression family with a potent stereo amplifier. Leveraging our innovative Super Rail circuitry, first unveiled in the Progression Mono, the Progression Stereo amplifier exploits this unique technology delivering remarkable control and fidelity to any connected loudspeaker.

With the final darTZeel NHB-458, it sets a new standard: after nine years of constant research and continuous development, this amplifier, not only it owns all the qualities of the NHB-108, already acclaimed by the whole audiophile world, but it goes further in revealing a very special machine in every respect.

The 800 series of amplifiers from EAR has received widespread and consistent acclaim from users and reviewers the world over. However, feedback from some quarters suggested that there was a need for an amplifier with similar sonic prowess but just a little more power.

Tim de Paravicini designed the EAR 509s with industrial grade components for reliability and performance. Built to handle the demands of professional audio environments, we added the option for it to be equipped with balanced inputs for those -professional applications.
