Bluetooth 5.2 AptX
This amplifier can be enjoyed straight out of the box with Bluetooth 5.2 AptX connectivity, supporting 24-bit HD streaming audio from your smartphone or tablet. It can also connect to Bluetooth headphones for listening after dark.

Phono Stage and DAC
If you don’t have a separate phono stage, Arcam have put careful focus into the on-board MM phono stage to ensure excellent sound from your turntable.

The onboard DAC uses the quality ESS ES9018 chipset and alongside three three analogue inputs, Arcam have included three digital connectors for enjoying your digital music sources as well.

High end design

Arcam has a long pedigree in amplifier design and the A5 is the culmination of many years experience. The Radia A5 is a Class AB design which ensures the best possible quality at low levels while allowing more power to be available at high volumes.

Class A is often used with a single output device, however, it is very inefficient and needs a large power supply. On the other hand, class B is more efficient but can suffer from cross-over distortion, especially at low output levels. Class AB was developed as a result and works in class A at low levels but gradually switches to class B as the volume rises.

Good connectivity
The Arcam Radia A5 integrated amplifier has good connectivity with two coaxial and one optical digital input, so you can connect a range of music sources. There are also three RCA line-level inputs as well as a good quality onboard MM phono stage. Additionally there is a preamp output to use it with a separate power amplifier. A wired Ethernet connection is provided and there is also a USB connector and trigger input. Speaker outputs are by standard gold-plated binding posts.
