Kenwood KA-7000 (1972)
A solid-state integrated amplifier from Kenwood's early-1970s flagship line. It puts out 50 watts per channel, has full tone controls, and comes in a heavy chassis with a silver faceplate.
Overview
The KA-7000 sits in the upper tier of Kenwood's integrated amplifier lineup of 1972-1974. Kenwood (Trio in domestic Japanese branding) had grown out of its 1960s tube and early-transistor designs by this point and was a confident solid-state company. The KA-7000 shows it: a substantial chassis, a well-designed power supply, and real attention to phono preamp performance.
It competed directly with the Pioneer SA-7100, the Sansui AU-7500, the Yamaha CA-700, and the early Marantz integrateds. Kenwood pitched it on build quality and feature set rather than sheer power. At 50 W/ch it put out slightly less than some rivals, but it had notably tighter THD figures and a more comprehensive control set.
