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.

HiFi+ Innovation Award 2021Primare have received an Innovation award from HiFi+ with the following citation:
“First founded in 1985 by industrial designer Bo Christensen, Primare’s is perhaps one of the most recognisably Scandinavian brands in audio. Its combination of minimalism and good performance all point to a Swedish brand.
So, when Primare uses a Swedish word to describe its ethos, perhaps we shouldn’t be too surprised. That word is ‘Lagom’ (pronounced ‘laah-goam’) and roughly translates to ‘just the right amount.’ In Primare’s world this means keeping everything in balance, harmony and proportion, and that the music – rather than the technology or the box in which it comes – should be the focus of audio.
To this end, Primare employs a very modular approach to its product design, such as its latest Ultra Fast Power Device module (used throughout the range), which shows what Class D can do in the hands of very competent design engineers.“

I25: Primare I25“The sound is clear, it is solid and dynamic, it has a bit of an analytical tendency and, above all, it does not impose any particular character on the whole. But it is not a tense technical performance, it remains impartial and close to the theoretical audiophile ideal. A big bonus is the possibility to expand its capabilities with a solid D/A converter module and/or the Prisma module, which will provide the comfort of the world of streaming and modern control. Overall, the Primare I25 is a frequency-balanced and tonal-neutral amplifier, well processed and very orderly – at least on paper, it is very close to the theoretical hi-fi ideal.”
High Fidelity, Poland, July 2019
I25: I25 Test“It turns out that the Primare I25 is a very versatile device that will fit most systems, will show off most discs in a nice way. Playing with a large, full sound in which the midrange is most important, but not because the frequency extremes are limited – absolutely not, as I would even say that the bass is slightly pronounced and the treble has a lot of energy – but we have such an impression because everything is sweet and pleasant.”
Fair Audio, Germany, June 2019
I25: Primarily Versatile“Even though Primare’s I25 Integrated amplifier’s cleanliness, deep-bass strength, and control can be considered to be prime virtues, it is first and foremost an all-rounder without any real weaknesses or anything that draws attention… The Swede, at all times, with its effortless homogenous musicality, unconditional control and balanced, slightly sonorous tonality, avoids sounding hard or flat. This makes the I25 suitable as an inspiring sounding companion for the long term – even in combination with more demanding loudspeakers.”
