The Nakamichi CA-7A is a late-1980s all-analog stereo control preamplifier with an onboard MC/MM phono stage and full remote control capability. It offers MC and MM phono inputs plus multiple line-level inputs, with a wide bandwidth of 1 Hz to 100 kHz and very low distortion rated at 0.002% THD, making it suitable for high-resolution vinyl and line-level sources. The unit provides front-panel Acoustical Fine Tuning tone controls (low, mid, high) that can be bypassed, allowing both precise tonal adjustment and a more direct signal path for critical listening. The CA-7A features a dual-toroid power supply architecture and is known for its solid construction and excellent measured performance, and is often used in vintage high-end systems alongside Nakamichi power amplifiers such as the PA-7 series.
