Arcam A25
The ARCAM A25 is the best sounding, and most feature rich of our Radia Integrated amplifiers. 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. New components and materials have been painstakingly analysed and reviewed to ensure uncompromising sound performance.
The rich feature set includes a USB-C input for your laptop, be it PC, MAC or Raspberry Pie!

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.

The A25’s warm, richly textured sound gives music an inviting, easy flow, while still delivering impressive grip, dynamics, and low noise. Gene DellaSala, Dennis Burger, and Mark Gusew all praise its refined presentation, strong stage depth, and handsome, compact design, making it a compelling integrated for small to medium rooms.
What Reviewers Are Saying
Pros
Warm, rich tonal balance that stays refined and listenable without becoming harsh.
Excellent low noise and distortion, with clean, detailed playback from digital and analog sources.
Strong dynamics, solid bass control, and convincing imaging/soundstage for its size.
Very well equipped, with USB-C, DAC, MM phono stage, Bluetooth aptX Adaptive, headphone out, and pre-out.

Cons
The built-in phono stage is good but not class-leading, with some low-frequency roll-off and weaker bass performance at higher input levels.
Bluetooth playback can feel volume-limited, which reduces headroom for some dynamic material.
The sound can tilt a little thick or relaxed with very aggressive music, so speaker matching matters.
No HDMI ARC or network streaming, so TV and streaming users may need extra boxes.
SOUND QUALITY PERFORMANCE 88/100
Reviewers consistently describe the A25 as warm, rich, refined, and easy to live with, with low noise helping fine detail come through clearly. It is praised for tonal realism and a pleasingly balanced presentation, though some writers note a little bloom in the bass and a presentation that can sound a touch relaxed with very aggressive material.
Transparency Resolution
89/100
The A25 is repeatedly described as low-noise and detailed, with fine detail easy to hear and a clean signal path that suits high-resolution sources. Audioholics measured very low noise and distortion, while Sound Advice highlighted how the digital board combines detail with tonal realism.
Tonal Balance Musicality
91/100
This is one of the A25’s biggest strengths in the reviews: it is called warm, rich, lush, sweet, and engaging, yet not overly dark or hard. Several reviewers stress that it remains refined and listenable with both good and poor recordings, which gives it broad musical appeal.
Dynamics
86/100
The amp is generally praised for strong drive, punch, and reserve, with multiple reviewers noting healthy power and good current delivery. A few comments temper that with suggestions that it can sound fractionally relaxed on very ballistic material or a little thick rather than especially fast.
Soundstage Imaging
88/100
Imaging and stage performance are described positively, with references to pinpoint precision, good depth and width, and a convincing sense of space. It is not usually presented as class-leadingly expansive, but it does enough well to support a stable and enjoyable presentation.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
88/100
Reviewers repeatedly praise the slimline chassis, clean industrial design, and generally high standard of finish. The large toroidal transformer and good thermal behavior get favorable mention, although one bench-test note about components singing under load keeps it from sounding entirely unqualified.
Features Connectivity
92/100
The A25 is unusually well equipped for a conventional integrated amp: it includes a built-in DAC, MM phono stage, headphone output, Bluetooth with aptX Adaptive, USB-C, coaxial and optical digital inputs, and a preamp output. The main omission reviewers mention is HDMI ARC, but the overall feature set is broad and practical.
Value for Money
89/100
Several reviewers say the A25 feels impressive for under its asking price and a compelling buy in its class, especially given the DAC, phono stage, headphone output, and overall refinement. The value case is helped by its strong performance and feature count, though it is still clearly a premium-priced integrated rather than a budget bargain.
