Pioneer - SA-8800 Solid state amplifier

The SA-8800 has the impressive feature of being a non-switching amplifier (NSA), specially created by Pioneer.

This is a type of amplifier that adopts the merits of class A and class B amplifiers, and stands out for keeping heat loss low and allowing transistors to operate continuously in the active region.

For this reason, a high power output is achieved with a very low distortion factor up to the highest frequencies.
