Product Information

The Pioneer A20 Amplifier is solidly built, sports a stylish design and delivers a detailed, rich and hugely enjoyable sound.

Pioneer's 'Direct Energy Design' and symmetrical construction allow the A20 to deliver an impressively clean sound. For the tweakers there are separate bass and treble, balance and loudness controls, whilst purists can utilise the direct mode, which disables excessive circuitry such as tone control, to deliver the sound unfettered. Infra-red input and output sockets allow you to integrate the A20 with the rest of your system and twin independently switchable speaker outputs allow bi-wired or multi-room setups. 

A brushed aluminium fascia and polished aluminium control knobs make the A20 a joy both to look at and use.

With the build quality and sonic performance we've come to expect from Pioneer presented in a package that mixes traditional hifi aesthetics with contemporary touches, the A20 is a truly desirable amp.
