Primare I25
I25 is an award winning modular full size integrated amplifier featuring our UFDP 2 ampliciation technology delivering 100 watts of power per channel, with the option of adding digital to analog converter and Prisma network player modules at any time.
Technology
I25 modular integrated amplifier is the latest iteration of Primare’s now iconic integrated amplifiers and among the first to use our new UFPD 2 power system, a radical reworking of Primare’s award-winning UFPD all-analog Class-D technology.
Providing 100 watts at 8 ohms of absolutely linear UFPD 2 amplification across the entire audible bandwidth, I25 delivers naturally fast, clean and agile sound with an unprecedented ability to bring music to life.
The modular design of the I25 allows for a sophisticated digital to analog conversion module, DM36, as well as a Prisma network player module module, SM35, to be added to the amplifier at any time for unprecedented system customization.
I25 continues a Primare tradition of delivering astonishing performance from compact and elegant integrated amplifiers for easy installation into virtually any living environment.
The look and feel of Scandinavia
We believe that every aspect of our products – the way they look, the satisfying feel of the controls – contributes to the overall experience of living with Primare. As a result, Primare products exude the hallmarks of Scandinavian design – simple, elegant designs, with approachable and easy to understand functionality.
An example of this is our signature control knob, known throughout the industry for both its appearance as well as how it feels in the hand as an input is selected or volume adjusted. – or as we say lagom, not too much not too little, everything in balance, proportion, and harmony.
Modular Design and System Building
We feel it is essential to offer modularity whenever possible in order to have just the right features, both now and for the future. Modular design is featured in the I25 and I35 modular integrated amplifiers, as well as the PRE35 modular preamplifier, all of which can be updated with DAC and Prisma modules, as well as the CD35 CD player that can have the Prisma module added, either at the time of purchase or at a later date. As a result, we are able to offer a carefully considered array of models and configurations in order to allow for device selection that best fits any system need. For example, a CD35 with Prisma module installed can be paired with an I35 integrated amplifier, allowing for a separation of analog and digital stages. Or, an I35 with DAC and Prisma modules installed can be paired with a DD35 CD transport, allowing for multi-room and multi-zone playback of every input, whether analog or digital source.

Primare I25 integrated amplifier — refined, incisive performance
Primare's I25 integrated amplifier pairs refined musical poise with muscular control, making it a standout 2x100W design for serious listeners. It delivers a highly resolving, neutral presentation that emphasizes clarity, dynamics and imaging, rendering instruments with convincing body and microdynamic detail. Reviewers at Audiophilepure highlighted the I25's speed, timing and ability to separate complex layers while preserving emotional involvement across sources. Sonically the amp offers tight bass grip, articulate mids and clean treble that create a spacious, well-defined soundstage. Built in a compact 11 kg chassis with black or titanium finishes and useful control ports (IR, 12V trigger, RS232), the I25 suits two-channel systems where resolution and timing matter most — small to medium rooms and revealing loudspeakers. With top-tier sonic performance for its class, the I25 is a compelling choice for critical listeners.
Pros
- Highly resolving and neutral presentation that excels at revealing microdetail and instrumental inflection.
- Strong dynamics and tight transient control for its 2x100W class, delivering crisp timing and musical drive.
- Generous, well-defined soundstage with solid instrument body and imaging that creates convincing in-room presence.

Dynamics
91/100
Primare's 2x100W (8Ω) topology is described as having 'strong dynamics', 'impeccable timing', 'tight focus' and a 'firm grasp of microdynamics'. For its power class this indicates excellent transient control and headroom, meriting a top-tier dynamics score.
Soundstage Imaging
90/100
The reviewer notes 'strong in-room presence' with performers portrayed 'with body and dimensionality in a truly spacious soundstage.' That language supports very good width, depth and image solidity.

Build Quality
88/100
No explicit reviewer comments on construction, but Primare's specifications (11 kg chassis, metal finishes available in black/titanium) and product positioning suggest solid component and chassis build. Score reflects good workmanship expectation without direct review evidence.
Features Connectivity
84/100
Unit offers 5x stereo RCA inputs, a line output, PRE output, IR/C25 remote control, 12V trigger and RS232. Lacks DAC, phono, balanced I/O, headphone out and streaming; modest extras (pre/tape outputs and remote/control ports) push it slightly above minimal baseline.
Value for Money
86/100
Price listed ~2800–2849 and reviewers did not comment on price-value explicitly. Per guidelines, default to a neutral baseline; the score modestly reflects solid performance in its segment but no explicit value praise in reviews.
