Audio Research SP9Preamplifier(1988) Description The SP9 Hybrid Stereo Preamplifier represents a further evolution of the innovative electronic design first embodied in the widely acclaimed Audio Research SP11 Stereo Preamplifier. The SP9 is not a "stripped-down" version of the SP11, but rather represents an adaptation of some of the SP11's patented hybrid technology to a simpler, more economical single-chassis format. Using just two 6DJ8 vacuum tubes (one in the phono section and one in the high-level stage) in intermediary gain stages, the SP9 expresses the musicality and natural "rightness" vacuum-tube preamplifiers have been noted for, yet it does so with the quickness and dynamic vigor of the best solid-state designs. Because its two vacuum tubes are used so conservatively, the SP9 will undoubtedly prove to be one of the most reliable and lowmaintenance Audio Research preamps ever up to 10,000 hours of service life are possible before replacement of these tubes might be necessary. And, replacement tubes are not required to be select, low-noise (and expensive) types. Audio Research brand vacuum tubes obtained from your authorized dealer will provide the best performance and reliability. Although the SP9 contains an on-board power supply (as opposed to the SP11's isolated supply), it is a highly advanced, tightly regulated design employing a shielded toroidal power transformer to minimize any potential problems of mechanical noise or hum. Location of this transformer in relation to special low-hum input circuitry has been optimized within the SP9 chassis layout to virtually eliminate transformer-related noise. (Note that while outboard power supplies have become a popular design trend among high-end audio manufacturers, simply isolating the power supply from the main chassis has little benefit if the basic design of the supply itself is second-rate. In such cases, outboard isolation may be little more than a cosmetic cure for more serious deficiencies.) While the SP9 is designed to provide superb playback from phono records, its high-level circuits have also been optimized for other popular input sources, including compact discs. In this respect, the SP9 is virtually overloadproof, insuring maximum enjoyment of today's most dynamic program material. And, with two tape monitor loops, the SP9 offers the tapedubbing flexibility so many listeners want but seldom find in an audiophile-grade preamplifier. Of course, all controls and switches used in the SP9 have been carefully specified and selected to insure minimal sonic degradation - as have the other active and passive components used in the construction of the SP9. While the SP9 is more affordable than some other Audio Research preamplifiers, its more modest price was not achieved at the sacrifice of component quality. Careful, elegant design, structural simplicity and efficient manufacturing techniques have all contributed to a standard of physical integrity and musical accuracy never before achieved in this price class.
