Reviews

• The A-77X and A-88X models were Pioneer's Elite series amplifiers at the time, with the A-88X leading the series in terms of features and also performance. The units probably evolved from their predecessors, the A-60 through A-80, which had fairly similar specs.
• All models (starting with the A-66X) have "of course" metal fronts and controls. The volume control of the A-88X is completely made of metal and is attached to the potentiometer with an Allen screw.

The A-88X is a typical fat Japanese amp: solid workmanship, full output power and connections with impeccable technical data.

• At the time, this model was Pioneer's top of the line. But just as typically Japanese: in Japan itself there was still a number larger.
