*SOLD* Magnificent is the best way to describe this beauty !!
It delivers a continuous power output of 65 watts per channel, min RMS at 8 ohms, from 20 to 20,000 Hertz, with no more than 0.1% total harmonic distortion.

But even more importantly, it has the strength and finesse to handle that power with a healthy respect for musicality.

The SX-850 has a super-quiet phono equalizer in a 3-stage direct-coupled design to achieve wide dynamic range and +- 0.2dB RIAA equalization accuracy.

A FET in the Tone Control section, plus a 2-step frequency turnover switch for Bass and another for Treble, 2-deck monitor/dubbing, 2-system speaker drive, separable pre/main and more, mean further control versatility.

The superb FM/ AM section uses a dual-gate MOS FET and a 4-gang variable capacitor to boost sensitivity and selectivity, a PLL IC in the multiplex to improve stereo separation, and a special Integrated Circuit in the AM for still better reception and less noise.

It’s the Pioneer SX-850 – the one you can trust to keep faith with your musical needs.
