From Pioneer regarding the TX-9500:

Inside it's one of the most circuit-packed AM/FM tuners Pioneer have ever built. And outside it's one of the cleanest and most simple to use. The Pioneer TX-9500 has a new streamlined look, logically-arranged switches and controls, and a scientifically-designed tuning system that makes it all look so easy. But it's what's inside that counts: dual-gate MOS FETs and a 5-gang variable capacitor boost FM front end sensitivity to a superb 1.5uV (IHF). The FM IF has 7 ICs with differential amps, 4 ceramic filters (with 2 elements each) and a wide-band linear detector to pinpoint selectivity at 85dB or better and beef up the capture ratio to 1.0dB (IHF). Even in stereo the S/N is a super high 75dB, with total harmonic distortion of 0.2% at 1KHz.Thanks to the PLL MPX (phase lock loop multiplex) demodulator, stereo separation stretches to a wide 35dB over the 50 to 10,000Hz range. Stability? Even in signal-weak or signal-strong areas your station comes in clean and fresh. Planning to record off the air? Hit the switch for the built-in 440Hz test signal generator and check the output level against your deck's VUs for optimum adjustment before the music begins.

From Pioneer regarding the SG-9500:

The complex control functions of the SG-9500 are not limited merely to the equalization of a simple program source, but can also provide precise tone corrections for the playback equipment (turntable and tape deck), speakers and listening room. Musical program sources can also be modified to improve the sound of technically inferior recordings or to tailor them to suit your personal taste. The SG-9500 is a highly versatile audio component.

From the Pioneer regarding SPEC-1:

The Spec-1 has differential amplifier circuitry incorporated in the equalization and tone control amplifiers. This is complemented by a dual positive and negative power supply system for all amplifier sections, which provides improved DC balance and stability, while eliminating click noises due to switching. An electronic muting circuit, employing a reed relay, blocks surge noise associated with power switch operation.

From Pioneer regarding the SPEC-4:

The Spec-4 employs DC construction which excludes capacitors from the NFB circuits and uses a dual transistor differential amplifier with a current mirror circuit in the 1st stage. This provides a stable operation and also high gain over a wide frequency range. The pre-driver stage is a class A circuit with a regulated current circuit for the load. This makes for high gain amplification with superior linearity. Furthermore, there is an overdrive limiter and power limiter circuit which is designed to protect the power transistors and make for added reliability.
