Pioneer A-88X Non-Switching Integrated Amplifier, a rare, superb beauty and sonically brilliant! Completely stripped down and rebuilt with all new HI-END capacitors. All connections on the rear of the amp have been also replaced with new quality gold RCA sockets and speaker binding posts. This 1986 integrated amplifier was part of the ELITE range, next model down from the C-90 Reference Control Amplifier and the M-90 Reference Power Amplifier. Pioneer also offered as an accessory, wood-grain sides, these panels gave the amp a classy look. We decided to construct a raw set from solid wood and high gloss them!

The history of this A-88X was that it was well kept and did not have much use, the new owner will appreciate the condition and the care we have taken to restore the magnificent piece!


RV HIFI is passionate about Vintage HIFI, so we believe in doing the job right!
