extensive listening tests

extraordinary longevity

Excellent measured performance is to be expected in world-class products, and Classé products deliver that performance. However, experience has shown that technical excellence alone is insufﬁcient to guarantee subjectively musical results.

For this reason, all Classé products are laboriously ﬁne-tuned during the development process by carefully controlled listening tests. Our ears are still some of the ﬁnest laboratory test instruments available, and nicely complement more traditional engineering test equipment. In the course of optimizing the circuitry for a product, hundreds of decisions are made based on the subjective impression given by substituting one high quality part for another.

As an example, we may listen to half a dozen 0.1% tolerance ﬁlm resistor components of the same value, from several different companies. Standard tests may show them all to provide identical results in terms of noise, distortion, and so forth. Yet, almost invariably, one selection yields some small improvement in the subjective reaction to the performance of the product under development. Less often, even a single such change can result in a surprisingly large improvement.

Multiply those various improvements by the dozens or even hundreds of such decisions that must be made before the product can be ﬁnalized for production, and you have a remarkable improvement, indeed – all based on careful listening tests, which we view as a necessary complement to the solid engineering you might rightly expect from Classé.

Another beneﬁt of having worked with highly reﬁned circuit designs so extensively over many years is that we have vast experience in what works well over the long term.

By using only the highest quality parts to begin with, and then using them in an informed way as a result of both accelerated aging experiments and actual long- term experience, we are able to design and manufacture products which we are conﬁdent will stand the test of time.

We are conﬁdent that your new Classé preampliﬁer will give you many years of trouble-free reliability and musical enjoyment, just as previous Classé products have given their owners.

The CP-700 employs an outboard power supply to provide the ultimate in performance. This unit includes a massive 135 VA toroidal transformer with ﬁve secondary windings to provide maximum isolation for both the positive and negative voltages required by each channel, as well as the voltage used by the control circuitry within the preampliﬁer itself.

This design approach ensures that the preampliﬁer itself sees only the pure, highly-regulated DC power it needs for handling the music signals, while the high-voltage AC mains is kept safely away from your music. In short, it creates an ideal environment in which the reﬁned circuitry of the CP-700 can operate to its full potential in service of your musical enjoyment.

cp-700 specifications

The Classe Audio CP-700 is a high-performance audio preamplifier that exemplifies the brand’s commitment to sound quality, design, and innovative technology. Tailored for audiophiles and music enthusiasts, the CP-700 combines superior build quality with advanced circuitry to deliver an immersive listening experience.

One of the standout features of the CP-700 is its robust digital processing capabilities. It includes a high-resolution DAC (Digital-to-Analog Converter) that supports audio formats up to 24-bit/192kHz. This ensures that every detail of the music is reproduced with outstanding clarity and precision. The preamplifier also boasts multiple digital inputs, including USB, coaxial, and optical, making it versatile enough to accommodate various audio sources.

The analog section of the CP-700 is equally impressive, featuring Classe's proprietary technologies that minimize noise and distortion. The preamplifier utilizes high-quality components and a carefully engineered circuit design that embraces a dual-mono architecture. This approach reduces crosstalk and enhances imaging, allowing listeners to experience a wider soundstage and more defined instrument placement.

Moreover, the CP-700 features a state-of-the-art volume control system. Rather than a traditional potentiometer, Classe employs a digitally controlled analog attenuator, providing precise volume adjustments without compromising the audio quality. Users can expect smooth and seamless changes in volume levels, enhancing user experience during playback.

In terms of usability, the Classe CP-700 offers an intuitive interface, with a large, bright display and a user-friendly remote control. The preamp can also be controlled via an app, adding convenience for modern users who prefer controlling their audio systems through mobile devices.

Another notable characteristic is its elegant design. The CP-700 features a sleek aluminum chassis with a minimalist aesthetic that fits well in various home theater or music room setups. This careful attention to design aligns with Classe Audio’s philosophy of marrying form with function.

In conclusion, the Classe Audio CP-700 preamplifier stands out for its high-resolution audio capabilities, advanced volume control, and exceptional build quality. It is an ideal choice for discerning listeners who seek an unparalleled audio experience without compromising on features or aesthetics. With its combination of digital and analog prowess, the CP-700 represents the pinnacle of modern audio engineering.
