What makes the inspiration integrated different from other constellation products?

Like all Constellation Audio products, the Inspiration INTEGRATED 1.0 takes full advantage of shared family technologies. Its design is based on the award-winning Inspiration PREAMP 1.0 and STEREO 1.0, combining the preamplifier and half of the stereo amplifier on a single chassis.

What is the size of the constellation integrated preamp?

The Integrated 1.0 measures 17”W x 5.5”H x 19”D and weighs 43 pounds, and its design draws heavily on those of the Stereo 1.0 and Preamp 1.0, as well as on core technologies that Constellation uses throughout its product lines.

How does the constellation audio integrated sound like?

Through the Constellation Audio Integrated 1.0, this is exactly how the track sounds. Through other amps, there is a softening of the transients and a melding of many of the sounds into a flat musical landscape. This is the antithesis of anything created by Jack White.

Is the Yamaha inspiration an integrated amplifier?

The only integrated amplifier it makes is in the Inspiration range and based on the Preamp 1.0 and Stereo 1.0 from that range, in fact it’s built with half of the power amplifier section found in the Stereo 1.0. Which means it offers 100 Watts per channel and doubles that into half the impedance, indicating a pretty serious power supply.

Integrated 1.0

The Constellation Audio Inspiration INTEGRATED 1.0 is the newest member of Constellation Audio’s most affordable Inspiration Series, and joins its preamplifier and amplifier line-mates in delivering the performance that is expected from Constellation Audio at a more affordable price.

Preamp 1.0

It’s remarkable how much of the technology from the Altair II and Performance series Virgo II preamplifiers is preserved in the Inspiration PREAMP 1.0. The core audio circuits are the same. The power supply retains its triple-transformer design.

Stereo 1.0

Our original goal when we founded Constellation Audio was to apply the talents of our "dream team" of top engineers and designers to creating the finest components the audio world has ever seen. According to many noted experts, we’ve done just that.

Mono 1.0

The Inspiration MONO 1.0 amplifier easily delivers 400 watts per channel into 8 ohms, doubling to 800 into 4 ohms. This is power enough to produce incredible, concert-hall dynamics with any speaker. Yet it is the size of a standard audio amplifier and weighs just 55 pounds.

Review: Constellation Audio Inspiration Integrated 1.0

Have you ever had a day where you feel as if every move you make is in sync with movements greater than you? As if you’re in step with something larger than the span of a step or day or lifetime?

Sexy Postcard

My best guess is in these cases our expectations get ahead of us. They get ahead of what’s right there, so we lose sight of the moment, unable to enjoy what is because of what should be.

Chopin: Nocturne in F Minor, Op. 55 No. 1

The Constellation Audio Inspiration Integrated 1.0 graced my system with a sense of universal time with music sounding perfectly in step, in control, and able to communicate the intricate mysteries of whatever I decided to run through it. This was the case no matter the speaker.

Venus In Furs

I listened to and loved the Inspiration Integrated 1.0 with each of the speakers in Barn for weeks on end. This process did not result in a winner, not even a favorite partner.

Schumann: Piano Sonata No.1 in F sharp minor, Op.11 – II. Aria

When the Constellation first arrived in Barn, I was listening to the Technics Stereo Integrated Amplifier SU-R1000 driving the Perlisten S7t speakers. If you read that review, you’ll see that I enjoyed the Technics and then some.

The Right Thing Is Hard To Do

If I were to list every piece of music I listened to through the Inspiration Integrated 1.0, that list would be as long as this review. That’s because I spent about 6 weeks with the Constellation in my system and I listen to music all day most days.

What is the Constellation Audio line?

Constellation Audio has been around since 2008, and in that time the California-based electronics manufacturer, founded by the same Australians responsible for Continuum Audio Labs, has launched four product lines. From bottom to top in terms of price, these are the Inspiration, Revelation, Performance, and Reference ranges of models, the last of which tops out with the Hercules II monoblock power amplifier ($190,000/pair). The entry-level Inspiration line has four members: the Stereo 1.0 stereo power amplifier ($12,500), the Preamp 1.0 preamplifier ($11,000), the Mono 1.0 monoblock power amp ($25,000/pair), and the subject of this review, the Integrated 1.0 integrated amplifier. Constellation also makes a pair of phono stages, a DAC, and a standalone power supply.

How much does a Constellation 1.0 weigh?

The Integrated 1.0 measures 17”W x 5.5”H x 19”D and weighs 43 pounds, and its design draws heavily on those of the Stereo 1.0 and Preamp 1.0, as well as on core technologies that Constellation uses throughout its product lines. One of the latter is the company’s minimum-feedback, class-AB, Balanced Bridged amplifier circuit, which uses N-type transistors throughout instead of a combination of N and P types, as is done in many other solid-state designs. Constellation claims a benefit of this practice: the positive and negative halves of an audio signal thus behave identically, to result in perfectly symmetrical output. Every Constellation amplifier model, including the flagship Hercules II monoblock, contains at least one Balanced Bridged module, each of which has eight output devices per channel. The module’s 125W power specification leads me to think that the Integrated 1.0’s spec of 100Wpc into 8 ohms might be conservative. The Integrated 1.0 is biased into class-A for the first couple of watts.

How many ohms does the Inspiration Stereo 1.0 have?

The Inspiration Stereo 1.0 develops 200 or 400Wpc into a respective 8 or 4 ohms. The Mono 1.0 doubles those values into 400 and 800Wpc, while the Integrated 1.0 halves them, producing 100 or 200Wpc into 8 or 4 ohms, measured using a 1kHz test tone at 1% THD+N. This makes the Integrated 1.0 not exactly a powerhouse — though Irv Gross, Constellation’s friendly VP of Sales, told me that the amp is stable down to 2 ohms. Ornery speakers aren’t necessarily ruled out.

What is integrated 1.0?

The Integrated 1.0 also makes use of Constellation’s Line Stage Gain Module, a “balanced circuit from two mirror-imaged amplifiers, one for the positive half of the signal and the other for the negative half,” with “hand-matched, ultra-low-noise FETs and servo circuits.” Throw in a linear power supply whose 1400VA transformer is coupled with 100,000μF of capacitance per channel, an analog volume control with a digitally addressed resistive ladder, and a headphone amp that outputs 800mW into 32 ohms, and you have yourself a nice little high-end integrated. Other specs include a frequency response of 10Hz-20kHz, ±0.5dB; total harmonic distortion plus noise of 0.035%, measured at 1kHz when delivering 25W into 8 ohms; an output impedance of 0.125 ohm; and output noise of -84dB, A-weighted.

What is the difference between the Simaudio and the Constellation?

There were two subtle differences. The Simaudio sounded a little airier and more extended in the treble, which made its sound seem bigger and, seemingly (though not actually), more transparent. By fine margins , the Constellation traded that spacious top end for a touch of smoothness through the mids that lent it a more robust tangibility.

Is the integrated 1.0 a good remote?

The Integrated 1.0 ’s aluminum remote control is one of the very best I’ve used. It’s simple and solid yet not too heavy, and its buttons have a satisfyingly “clicky” action. And it lets you turn the amp off and on, which is not always a given. In my experience, good remotes often don’t earn the attention they deserve, despite the fact that most users almost always interact with the remote more than the controls on the component itself. This is a good remote. Nicely done, Constellation.
