Cary Audio Design CAD 808, Rocket 88 R guide

even higher overall power output levels to try to solve the clipping problem. In reality, we believe the most critical aspect is how fast a recovery an amplifier can achieve after overload. With the incredible dynamics range of live and recorded music, even 2,000 watts of power is potentially not enough. Most of the music being listened to in an average home listening room is only requiring about 1-3 watts of power. It is on the transients of loud low frequency program material that tremendous signal voltages will appear at the input of the amplifier. It is in this situation that the overload recovery ability of an amplifier is of critical concern.

The Rocket 88 R extols its merits in the ability to handle transients and instantaneously recover from brief or even extended overloads. The Rocket 88 R will overload symmetrically at any frequency in the audio bandpass. It will also yield faithful reproduction of extremely low frequencies at full output levels. The power transformer, the power supply regulation and the output transformer design and careful shaping of the overall frequency response curve all play a very important part in the ability of the Rocket 88 R to recover quickly when overloaded. If one were to monitor the high voltage rail voltage of the Rocket 88 R during soft and also loud music passages it would be found there is no more than a volt or so change from soft to loud passages.

Another technical feature of your new Rocket 88 R amplifier is unconditional circuit stability. The Rocket 88 R maybe operated with no load (without speaker) without damage to the amplifier, output transformer or tubes.

Operating the Rocket 88 R stereo amplifier is a simple procedure since each unit is designed for long term stability in virtually any home operating situation. Therefore, if the unit is operated outside the parameters outlined in this owner’s manual, damage may result. Please read this manual carefully before putting your new Rocket 88 R amplifier in operation.

The following definitions are applicable to this manual. These definitions must be followed explicitly.

CAD 808, Rocket 88 R specifications

Cary Audio Design has long been known for its high-end audio components, and the Rocket 88 R and CAD 808 amplifiers exemplify the brand’s commitment to excellence in audio performance. The Rocket 88 R is a tube amplifier that combines classic design with modern technologies, making it a popular choice among audiophiles who appreciate the warmth and character of tube sound. The CAD 808, on the other hand, is a solid-state powerhouse that brings to the table unparalleled clarity and power, providing a perfect counterpart to its tube-based sibling.

The Rocket 88 R is built around a unique dual mono configuration that allows each channel to operate independently, minimizing crosstalk and enhancing stereo imaging. This amp utilizes a pair of 6550 power tubes, delivering an impressive output of up to 100 watts per channel in push-pull mode. The result is a rich, harmonic sound that brings music to life, allowing listeners to experience their favorite tracks with an emotional depth that only tubes can offer. Additionally, the Rocket 88 R features Cary Audio’s proprietary Ultra-Linear and Triode switching modes, providing audiophiles with the flexibility to choose between a more powerful, dynamic sound or the intimate, lush qualities of triode operation.

The CAD 808 amplifies the experience even further with its advanced solid-state design. Featuring robust power supply and output stages, the CAD 808 is capable of delivering a staggering 200 watts per channel, ensuring that it can drive even the most demanding speakers with ease. Incorporating state-of-the-art technologies such as high-current output transistors and a fully discreet output stage, the CAD 808 minimizes distortion and maximizes input sensitivity, resulting in crystal-clear audio reproduction. Its low negative feedback design not only enhances the overall sound quality but also improves the amplifier's transient response, providing listeners with a more dynamic and engaging listening experience.

Both amplifiers boast beautifully crafted chassis with a blend of classic aesthetics and modern functionality. The Rocket 88 R is complemented by its glowing tubes and polished finishes, while the CAD 808 showcases a sleek, contemporary look with a user-friendly interface.

In conclusion, the Cary Audio Design Rocket 88 R and CAD 808 amplifiers stand out as exceptional choices for audio enthusiasts seeking both tube warmth and solid-state clarity. With their unique technologies and remarkable design characteristics, these amplifiers promise to elevate any audio system, ensuring an unforgettable listening experience.
