The new ARCAM Radia A25 Integrated Amplifier is the best sounding, and most feature rich of the Radia series. The visual luxurious highlights hint towards the more luxurious musical experience that it offers. This is achieved with a 5th generation Class G amplifier design. You can expect the best sound quality and dynamics from what has always been a better sounding, and more efficient Class of amplifier.
The rich feature set includes a USB-C input for your laptop, be it PC, MAC or Raspberry Pie! This augments a Bluetooth solution that includes Qualcomm AptX Adaptive technology with 24-bit HD audio to ensure the best sound quality no matter what you are playing. It can also connect to Bluetooth headphones so your listening experience can continue sensitively after dark.
Like any ARCAM integrated amplifier, we pay particular attention to the built in phono stage to ensure your records sound as lush and engaging as possible.
