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.

    I35 Prisma: Really everything in it!

    “In terms of sound, the I35 brings out the big guns here […] The Swede illuminates the stage deeply and widely, taking care of every detail, such as the instruments that are sometimes placed far out in the stereo panorama or the powerful, sensitively played bass, which, like the old master’s still fresh voice, is transmitted almost crystal clear […] It’s all incredibly fast and natural in its appearance. Lively in the best sense!”

    “With the I35 Prisma, Primare has succeeded in creating a versatile all-rounder that offers excellent network control, especially in terms of user experience […] In 2018, user experience is a top priority. Simple, quick operation and intuitive access to various online services – ideally throughout the house. Primare’s I35 Prisma masters this maxim with ease and also offers great sound quality. With a market value of 4,500 euros, the I35 Prisma is anything but a bargain, but the user definitely gets his money’s worth here!”

    I35+CD35 Prisma: Dream Couple of Quality

    “In general, Class D amplifiers are characterised by an extremely high efficiency of around 90%. They are therefore extremely efficient and therefore generate little waste heat. Large cooling fins are not necessary; the I35, despite its high performance, only needs a few small heat sinks attached directly to the components […] We were particularly impressed by its breathtaking speed. The amplifier organised the complex sound in a lively and tight manner, skillfully distributing its almost endless reserves and achieving maximum dynamics, while the CD player brought the finest details to light. What a successful combination! ” Stereoplay Highlight

    I35 + CD35 Prisma: Primare CD35/I35 Prisma Network/CD Player & Amp

    Cool Velvet – There’s something very alluring about the sound of this CD player/integrated amplifier. Working as a pair, with the CD35 acting as a digital disc transport for the I35 – one is immediately struck by the smoothness of the music. Indeed, they serve up an almost velvety rendition of whatever recording you choose to play. It’s an easy-going presentation yet one that’s authoritative, the combination rising to any challenge without sounding flustered.”

    I35 Prisma – Editors’ Choice Award 2022

    “Primare’s 150Wpc Class D integrated is teeming with connectivity—Wi-Fi and Ethernet for network-based storage and streaming services like Tidal, Bluetooth, and AirPlay. (It can also be configured analog-only.) Sonically it walks the straight and narrow with solid, pitch-precise behavior in the bass, a full midrange, and a treble that doesn’t etch or irritate. Its character veers slightly to the cooler side of the tonal spectrum, and transient behavior is swift and clean. Picking up on the leading edges of a tambourine rattle, a trumpet blast, or even the fingernails of a classical guitarist is part of the enjoyment of living with the I35. A rock-solid performer.”

    I35: Editor’s Choice Award 2021 Best Buy All-In-One Integrated Amplifier

    Primare I35 Prisma is one of those rare hi-end devices that can satisfy many needs in a single device, with comprehensive connectivity and streaming, high amplification efficiency, and natural, rich and emotional sound quality. Not only worthy of the honor of the Editors’ Choice Award 2021 in the category “Best All-in-One Integrated Amplifier”, we consider that the Primare I35 Prisma is the amplifier design that leads the trend in the industry for the coming years.

    I35 Prisma: 2021 HiFi+ Integrated Amplifier of the Year (up to £10,000)

    “If ever there was a product that exhibits the notion that ‘the whole is greater than the sum of the parts’ it’s the Primare I35 Prisma… Perhaps it’s the absence of nonsense, the way it makes everything sound musically entertaining and enjoyable, or perhaps it’s the sheer ease of use. I’m pleased on a number of levels to have stepped from I35 to I35 Prisma, even though I suspect in today’s world most people will just opt for the full-fat Prisma version. But that insight into how we relate to streaming and how it changes our perception for the better will stay with me. Thanks!”

    HiFi+ Innovation Award 2021

    Primare 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.

    I35 and CD35

    “But the most interesting thing is that, choosing an intermediate solution (I35 only with DAC, and CD35 – in the full version, with a network board), but while having to pay a bit extra, you get the most flexible option. First, the system has two different DAC characteristics… Secondly, with additional digital inputs, it is possible to use not only more sources, but also alternative signal paths between the amplifier and the universal network CD player (one of them can be configured by cables specifically for some musical genre). After all, the SM35 Prisma streaming board can be moved from source to integrated if you want to try out a different configuration or part with the CD player altogether.”

    I35 Prisma Review

    “Primare I35 Prisma is a gem of an amplifier. As a network player, it can stream almost anything, both audio formats and music services. And as an amplifier, it sounds brilliant.

    Its biggest advantage is that it tells the truth. It sounds both neutral and tight, and lets the speakers determine the final sound signature. The amplifier keeps the sound image whether you play low or high. It will work with the vast majority of speakers, the magic of the music flows out anyway. Special Recommendation / 5 stars”

    I35 Prisma HiFi+ Review

    In a very real way, I’ve not had a more immediate example of just how potentially game-changing this is, even though I’ve been working with computer audio in some way or form since the Napster days. This isn’t a ‘technology’ issue, it’s one of philosophy of listening and the psychology of the listener. You change your way of thinking between ‘I35’ and ‘I35 Prisma’ and the change is well met and worth making.  

    The addition of Prisma almost immediately changes your perception of the Primare I35 from ‘amplifier’ to ‘ complete music-making entity’. It stops being just another product on the shelf, because it challenges the need for the rest of those products on the other shelves in your system. Even with a significant collection of unripped discs playing through a disc spinner of some description, you find yourself drawn almost inexorably to streaming; not in some Svengali-like way and not just for simplicity. It’s because music happens that way and you want to get more of it.

    The combination of the Danish speakers and the Swedish amplifier is very successful. After the review of the Dynaudio Contour 20i and the Primare I35 Prisma, together they form a Scandinavian variant for a fast and dynamic reproduction, coupled with a high degree of transparency. They offer the listener a deep insight into the details and emotions of different music styles. What’s not to like?”

  • EISA, International, August 2019

    “Recipient of a previous EISA Award, Primare continues its winning ways with this I35 amplifier and CD35 Prisma CD/network player. The amplifier is a simple, but fabulous- sounding, all-analogue design that delivers plenty of power using the company’s UFPD 2 amplification. Its modular design means you can add Primare’s DAC stage, and the Prisma network/multi-room module, when required. The CD35 Prisma CD player is also fully networked, offering wired and wireless connectivity for AirPlay, Bluetooth and Spotify Connect, as well as Chromecast built-in to access thousands of streaming services. This is so much more than a simple CD player/amp system: It’s the future of hi-resolution home hi-fi.”

    I35 Prisma: New Blood

    “Never have integrated amps been asked to do so much musically and functionally. But any way you want to listen, the I35 Prisma is at your beck and call. Maybe you only want to stream from Tidal or one of the other services. Or play back music from a computer or network storage. Maybe you’ll never spin a CD or an LP, or even own a recording in any physical format. The I35 is non-denominational. But like a virtual butler, it’s poised at the ready should you change your mind. In sum, Primare’s latest is a rock-solid performer excelling in a highly competitive bracket. It met or exceeded all my expectations.”

Tonally, the I35 is rich and satisfying rather than bright and breezy, and yet it comes over as both energetic and dynamic sounding.”

    I35 Prisma + CD35 Prisma: Primare I35 Prisma and Primare CD35 Prisma

    “I35 Prisma illustrates the soul and sense of music with high tonal grip and low sibilance, nicely paints vast music landscapes and, at the same time, provides a naturally fast, transparent and agile sound. What’s more, the Swedish integrated has an inexhaustible ability to “revive” recordings. For example, on the album Keith Jarrett Trio “Somewhere” (ECM – 2009) the piano of the Steinway Grand Master, vibrating Peacock double bass strings, and DeJohnette’s delicate hi-hat drums were clearly present in the room, creating thus a perfectly balanced picture rich in detail and texture, providing the perfect insight into the emotional core of trio music.”
