FAQ — Arcam A25+ Integrated Amplifier with Bluetooth and Auracast
How does the Class G amplification in the A25+ compare to Class A/B models like the A15+?
The Arcam A25+ Integrated Amplifier with Bluetooth and Auracast utilizes Class G topology, which runs in pure Class A for low-power listening to eliminate crossover distortion. When demanding musical peaks occur, higher-voltage power rails instantly engage, offering greater power (100W vs 85W), superior grip over low-impedance speakers, and lower thermal dissipation than traditional Class A/B designs.
What is Auracast technology on the Arcam A25+?
Auracast is a Bluetooth LE Audio feature that allows the A25+ to broadcast its audio output wirelessly to an unlimited number of nearby compatible Auracast receivers, earbuds, or speakers simultaneously.
Can I connect my Mac or PC directly to the A25+ for high-resolution audio?
Yes. The A25+ includes an asynchronous USB-C input connected directly to its internal ESS SABRE ES9280A PRO DAC, supporting high-resolution files up to 32-bit/384kHz PCM and DSD256.
Does the A25+ feature pre-outs for an active subwoofer?
Yes. It includes a line-level stereo RCA preamplifier output (Pre-Out), allowing simple connection to a powered subwoofer or an external power amplifier.
