Most would agree that 1978 was peak Pioneer, but even the naysayers would have to admit that the SX line is absolutely iconic. From the crystal-clear readout framed by walnut and machined aluminum, down to the mirrored bezel on each knob, the attention to detail is palpable. Those details run deep, making the SX-950 one of the most sought after vintage receivers. This example has earned a bit of character after nearly 50 years, but we've serviced it from top to bottom, and this piece is in top working order. Take home the clarity, power, and precision the 950 is known for.

- The History of Pioneer
- Pioneer was founded by Nozomu Matsumoto in 1938 in Tokyo as a radio and speaker repair shop. In December 1953 Mr. Nozomu Matsumoto succeeded in developing the first domestic dynamic speaker made of original parts. It was named A-8 and marketed in Japan under the Pioneer brand. It later became the origin of the HiFi ...

- Liner Notes
This distinctive package of plenty includes up-to-the-minute circuitry throughout its handsome construction, and then gives plenty of power to boot: continuous power output of 85 watts per channel min RMS at 8 ohms, from 20 Hertz to 20,000 Hertz with no more than 0.1% total harmonic distortion.
But big power is only one important attribute of this new receiver - you also get an FM front end that performs with outstanding stability and sensitivity, thanks to the use of a pair of dual gate MOS FETs in its RF amplifier and mixer, an advanced FM IF section that includes three 2-element ceramic filters and a large scale integrated circuit, plus a multiplex section for FM stereo broadcasts that uses the innovative and advanced phase-locked loop IC for excellent separation characteristics.
The result is a flawless kind of sound that is unmatched in tonal quality by any comparably-priced receiver now on the market, plus the radiant good looks of Pioneer design and human engineering. The SX-950 by Pioneer: Something extra everywhere.
