Amplifier Placement and Set Up

In general, the location of your new Rocket 88 R amplifier is not critical. The best placement in your system is near the speaker system with short lengths of speaker cables. Certain precautions must be taken to ensure optimum performance. Avoid hot locations near radiators or other heating units. Keep the top of the Rocket 88 R clear of books, paper, or other equipment to protect against overheating.

Power Requirements

The Rocket 88 R is designed to operate from house current mains. The design voltage is 117 VAC at 50/60 Hz. (Export models are 117 or 240 VAC at 50/60 Hz, depending on destination.)

Cables

The speaker cables to the speakers can be any convenient length your setup requires. Please choose speaker cables of sufficient size to preserve the outstanding performance capabilities of your Rocket 88 R. Heavy gauge #14 AWG wire is suitable for distances up to 10 feet; #12 AWG for 25 feet. Our recommendation for best sound is to place the Rocket 88 R in between the stereo pair of loudspeakers. Use heavy duty loudspeaker cables with a length to reach from the Rocket 88 R to the speakers. Avoid long lengths that have excess slack. If your loudspeaker has the facility for bi-wiring, then by all means use separate cables or bi-wire speaker cables. Your Authorized Cary Audio Design Dealer will have proper speaker cable in stock for this purpose.

Signal input connection is made via the input jacks on the rear of the amplifier located next to the output binding posts. The interconnect cables from the output of the preamplifier can be any convenient length your setup requires. Through the years we have found that using tube amplifiers like the Rocket 88 R, it is better to have short loudspeaker cables and long interconnect cables to the preamplifier. The choice of a high quality shielded interconnect cable is important. Once again, your dealer will have the proper cables in stock for this purpose.

The tubes used in your new Rocket 88 R have gone through a 48 hour burn in process and testing with your individual Rocket 88 R. They are matched and labeled on the tube boxes. Look at the top panel of the Rocket 88 R for the proper placement of the tubes. Be careful to insert the tubes in the proper sockets with the key way in order. At the end of this manual you will also see a block diagram of the tube layout. Your new Rocket 88 R is ready for operation after the speaker, interconnect cables and the vacuum tubes have been installed.

AC Power Switch

Simply turn the AC power to the ON position (the red bias LED’s will light). After 30 to 60 seconds observe that all tubes are lit (filaments) and the green eye tubes are

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.
