The Pioneer A27 is one of the highest quality integrated amplifiers Pioneer has brought to the market!
Up to 30W, the A 27 works in pure Class A mode.
The Pioneer A-27 is exceptionally well preserved, almost in collector's condition.
The device was meticulously overhauled 5 months ago for €750 and sounds like it did when it was first launched 40 years ago.

Der Pioneer A27 ist einer der hochwertigsten Vollverstärker den Pioneer auf den Markt gebracht hat!
Bis 30W arbeitet der A 27 im reinen Class A Modus.
Der Pioneer A-27 ist außergewöhnlich gut erhalten, quasi im Sammlerzustand.
Das Gerät wurde vor 5 Monaten für 750€ penibelst überholt und klingt wieder wie bei der damaligen Markteinführung vor 40 Jahren.
