How much does a Centaur II stereo power amplifier cost?

At first glance, one might be forgiven for wondering what’s going on here – after all, California-based Constellation Audio already has a Centaur II stereo power amplifier on its books, selling for a not inconsiderable 48,000.

How many MOSFETs does the Centaur II 500 use?

Like all Constellation amplifiers, the Centaur II 500 is based on the company’s Balanced Bridged topology, which combines single-ended output modules, each of which uses eight N-channel MOSFETs to produce the desired output power.

What is constellation’s inspiration stereo amplifier?

Larry Greenhill reviewed Constellation’s Inspiration Stereo 1.0 power amplifier in April 2018. The Inspiration Stereo costs $11,000, delivers 200Wpc into 8 ohms (23dBW), and on the surface looks very similar to the Performance Centaur II 500.

What makes Centaur II different from Centaur?

Centaur II builds on the original Centaur’s signature blend of musicality and muscle with improved deep bass performance; the greater detail and smoother textures of extended Class A operation; and dynamics that are, quite literally, staggering. No matter what you expect from a stereo amplifier, Centaur II can deliver far more.

What type of transistor does Centaur II use?

Centaur II instead uses only N-type output transistors.

How many watts does a Centaur II amplifier have?

At 2 ohms, an impedance few amplifiers can handle, Centaur II delivers a staggering 800 watts per channel. Even at such high output levels, the modular amplifier design is inherently stable; unlike many amplifiers, it does not need a Zobel network at the output to damp high frequencies.

What is Centaur II?

Centaur II uses the same balanced bridged circuit topology found in all Constellation Audio amplifiers. The fully complementary design uses separate amplifiers for the positive and negative halves of the signal, ensuring the lowest possible noise and the best possible frequency response.

What is a Centaur II 500?

Centaur II 500 is an unexpected but very happy result of our upgrade from the original Centaur to Centaur II. When they designed the upgrade, our "dream team" of the world’s finest audio engineers ended up with an amplifier they knew could deliver far more than its rated power, if only the power transformer could provide enough voltage. As an experiment, they installed one of the transformers from our Reference Series Hercules II into a Centaur II Stereo chassis. The experiment worked even better than they imagined, producing Centaur II 500: a stereo amplifier with the same power rating as two Centaur II monoblocks.

What is the gain module on a Centaur II 500?

The Line Stage Gain Module uses ultra-low-noise FETs and a unique servo circuit to maintain an essentially perfect balance between the positive and negative halves of the audio signal, even if the signal from the source device is not perfectly balanced.

Why is the Centaur II 500 removed from the signal chain?

Thus, it can be removed from the signal chain to increase overall system transparency to a degree conventional preamp/amplifier combinations cannot equal. When Centaur II 500 is added to an audio system, compromise is removed.

What is the circuitry of a Centaur II 500?

Centaur II 500’s circuitry is fully balanced from input to output, with separate circuits used for the positive and negative halves of the audio signal. Only discrete transistors and other components are used in the audio path; we do not compromise by passing the signal through integrated circuits.

What transformers are used in the Centaur 2 500?

Centaur II 500 borrows one of the colossal power transformers used in the Reference Series Hercules II, our flagship amplifier. The transformer’s size allows it to deliver incredible peak output, while its toroidal design keeps its magnetic field well-confined.

What happens when you add Centaur II 500 to your audio system?

When Centaur II 500 is added to an audio system, compromise is removed. No matter what speakers are used, or what music is played, Centaur II 500 will always be up to the dynamic demands, while reproducing all the musicality and detail of the very finest high-resolution recordings.

How much does the maximum voltage of each capacitor increase in Centaur II 500?

While the number of power supply storage capacitors is the same, the maximum voltage of each capacitor increases by 30 percent in Centaur II 500. We did this in order to handle the higher rail voltages necessary for the higher power rating, but it has the nice additional benefit of further increasing total energy storage.

What is a Centaur 2 500?

As an experiment, they installed one of the transformers from our Reference Series Hercules II into a Centaur II Stereo chassis. The experiment worked even better than they imagined, producing the Centaur II 500: a stereo amplifier with the same power rating as a pair of Centaur II monoblocks’.

How much does a 500 stereo save?

And, as we’ve seen, the 500 Stereo saves you over £34k compared to a pair of those mono amps – beginning to look like a bit of a snip now, isn’t it? Of course, just slamming in a bigger transformer – actually one of the pair of 3kW-capable devices the Hercules II Stereo uses – isn’t the whole story. In addition, Constellation has increased the maximum voltage of each of the power supply capacitors by 30% to handle the new higher rail voltages. However, the output stages and their heatsinking were left untouched, as they were already up to the demands of the increased output.

How much does a Centaur 2 cost?

So the $64,000 question must surely be ‘what is this second version, dubbed the Centaur II 500 Stereo, bringing to the party?’.

How to tell if Centaur II 500 is in standby mode?

After connecting the Centaur II 500 to the wall socket with its 20A IEC cable, you turn it on with the rear-panel Master power switch, which resets an internal circuit breaker. The LED in the center of the front panel glows red, indicating that the amplifier is in standby mode. Pressing the left side of the front-panel control bar for three seconds brings the amplifier out of standby—the LED flashes green, to indicate that the amplifier is warming up. A minute later, the LED glows steady blue: the amp is ready to play music.

How many ohms does a Centaur II 500 have?

(The Centaur II 500 is specified as offering 250Wpc into 8 ohms.)

What amplifier did Wilson use?

The Wilson speakers, driven by the Constellation amplifier , were a transparent window on the acoustic of the Amsterdam hall where the recording was made.

What is the only hi-end magazine providing comprehensive measurements for audio equipment?

Thank you JA for the measurements ………. Stereophile is the only hi-end magazine providing comprehensive measurements for audio equipment (so far) 🙂 …………

How many watts does the Constellation have?

Constellation should call it a 2,000 watt per channel amp, the most powerful amplifier, ever. It is such a winning amp that audiophiles will get tired from all the sonic winning it does?

Can a 3000W transformer be used as a 1600W power amplifier?

any amplifier equipped with "some" 3000w power transformer could ever provide continuous output of 1600w simultan eously per channel – or anything close for that matter since there is always more to be stably fed in a power amp than merely output transistors. Curious thing is that Constellation Hercules II stereo amplifier that sports twice the aforementioned transformer and presumably larger output stages comes along with more conservative specifications which most probably will be exceeded by the actual measurements at the test bench.

Do Zippo lighters have a lifetime warranty?

ps. Zippo lighters all have a "Lifetime" warranty ( for gods sake ) and they seem to appreciate in Value as they get older.

How much does a Centaur monoblock cost?

The schematic is identical, but the Hercules features cost-no-object parts such as Vishay foil resistors. This $54,000-per-pair Centaur monoblock delivers 500W into 8 ohms, which is more than sufficient to drive all but the lowest- sensitivity loudspeakers.

What does a centaur sound like?

The Centaurs sound very much like the Hercules, with tremendous transparency and resolution, a big and open spatial presentation, and a feeling that the amplifier is light on its feet dynamically. The overall balance leans slightly toward the upper- midrange and treble, with very airy and highly resolved midrange and treble. The Centaur’s bottom end is full and satisfying, but not the last word in weight and heft. The bass tends to be quick, agile, and articulate. Resolution and transparency are simply world- class—this is an amplifier that allows you to hear back through the playback chain with every detail highly resolved.

How much does a Hercules cost?

Although the Hercules delivered reference-quality performance, its $140,000-per-pair price put it out of reach for all but the most well-heeled of audiophiles. Plus, who really needs 1100W into 8 ohms (and 2kW into 2 ohms)?

Who makes Constellation Audio?

Constellation was founded by the principals behind the Continuum Caliburn turntable. For Constellation Audio, they assembled a team of the world’s greatest designers to create a new line of reference-grade electronics, a team that included among others John Curl, Bascom King, Demian Martin, and James Bongiorno, all led by industry veteran Peter Madnick. (Sadly, James Bongiorno, the man behind Ampzilla and Great American Sound in the 1970s, passed away January 10, 2013.)

What is a Centaur II amplifier?

How many watts does a Centaur II use?

Centaur II’s incomparable audio circuitry would achieve little without a clean, abundant source of power. This is why we used a 1,600-watt, custom-wound toroidal transformer with separate windings for the left and right channels. Each channel effectively has its own source of power, so high demands on one do not affect the other. Fully regulated supplies for all line-level circuits eliminate interference from outside sources.

How many ohms does a Class A power supply have?

New power supply with 3 times the capacitance. Higher bias current for extended Class A operation. 250 watts per channel into 8 ohms, 800 into 2 ohms. Fully discrete balanced bridged circuitry for extraordinary fidelity. Larger, deep-fin heat sink for efficient cooling and outstanding reliability.
