Arcam A25 Integrated Amplifier Black

ARCAM A25 is at the top of the range of integrated amplifiers of the new Radia Series. It has more functions and the sound, using Class G, is at the highest level. Furthermore, the luminous aesthetic details make it luxurious and unique. The impeccable sound result is obtained thanks to a Class G amplification project now in its fifth generation. Sound quality, dynamics, efficiency are at the highest levels. Both the components and the materials used have been carefully analyzed and reviewed to guarantee uncompromising quality.

The input equipment is very rich: starting from a USB-C input to connect a laptop, be it PC, MAC or Raspberry Pie. Added to this is a Bluetooth receiver with Qualcomm AptX Adaptive technology with 24-bit HD audio to guarantee the best sound quality regardless of the media used. In addition to receiving, it also has the ability to transmit the Bluetooth signal, for example to connect wireless headphones and listen to your favorite program without disturbing other members of the family.

As in every ARCAM integrated amplifier, particular attention has also been paid to the built-in MM phono stage, to ensure maximum involvement even from vinyl records, which are increasingly present on our market.
