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.

Design philosophy

All of Primare designs are a result of our Practical Design Approach, resulting in a focus on two fundamental design elements:

  1. Thoroughly implemented power supply designs – so that all elements of any design to operate effortlessly at their fullest effectiveness. Every product and sub-circuit demands unique power supply solutions – a more conventional linear supply or advanced switch mode main supply may work best dependent upon the application, and carefully crafted individual discrete power supplies are strategically inserted into the circuit to deliver power exactly where and how much is needed.
  2. Artfully crafted ultra-short signal paths – so that each individual component and sub circuit operates sympathetically to achieve a cohesive whole. Elegant and simple electrical designs are used in even the most complex product, utilizing ultra-short signal paths with all gain in one device whenever possible.  Ultimately, this results in fewer, higher quality parts for a reduction in associated distortions and an increase in overall electrical efficiency.

To that end, basic technologies have been selected to realize those benefits:

  • 2 and 4-layer double-sided circuit board construction allows for the most direct and efficient layout of circuit components not only for the shortest signal path, but also to more easily achieve a sympathetic layout of circuit and sub-circuit components for best performance.
  • Surface mount components are used whenever possible as this allows for direct connection of the circuit device or component to the circuit board trace with the solder being used solely to mechanically hold the part in place. The elimination of the small metal lead or wire at each connection point in a more conventional large scale circuit device or component cumulatively shortens the signal path. Additionally, conventional large scale components demand through hole or “eyelet” construction, limiting direct contact of the component’s lead to the circuit board trace and resulting in the solder providing electrical connection as well as mechanical connection for the device. Neither solder nor the metal used in the leads of most large scale devices provide the best signal transmission, therefore limiting potential performance of even the best designed circuits.
  • Class D amplifier technology has many inherent advantages, one of which is the ability to locate the heat sink directly on the circuit board within the amplification module, considerably reducing circuit path length and allowing for the power output devices to be directly connected to the speaker output connection posts.

Amplifier Technology

Input section

Carefully crafted input circuitry utilizes relays for input switching providing better isolation and sound than found in more conventional CMOS (Complementary metal–oxide–semiconductor) switches.


  • Improved 2 x 4 channel balanced mode volume control IC selected for optimal channel balance and low listening level performance.
  • The latest generation OLED display technology used in the I35 was originally developed for the automobile industry to ensure long life in even the most hostile environments, and improved readability due to greater consistency of color value and brightness level.
  • Auto sense input circuitry automatically selects any input source as it is activated.
  • C25 IR remote control with completely new, proprietary control codes for faster response and reduced interference.
  • RS-232 connection, in addition to being used for component quality control testing of each and every product, allows for the use of whole home system control technologies such as Control 4.
  • 12V triggers for coordinated system turn on and turn off.

Control Configuration

Either from the front panel or C25 IR remote control, the I35 Prisma can be configured to best suit system needs:

  • Input settings
    • Status – enable or disable the input to make it visible or not, so only those you use are visible for easier input selection
    • Alias – edit the alias, or rename, each input to give it a specific name, for easier identification
    • Auto-sense – enable auto-sense to determine which inputs will be automatically selected when a signal is detected
    • Volume – choose between variable or fixed volume, allowing any input to pass through the preamp stage to connect directly to the amplifier for use of within a home theater system configuration.

Or fixed gain setting allows for any input to be use in a theater or surround sound pass through configuration

    • Input Gain – adjusting the input gain so that all inputs to be at the same relative volume level, and as result the ability to raise or lower overall gain for preferred output volume setting
  • Audio Settings
    • Balance – to adjust the output balance between the left and right speaker
    • Startup volume – sets the volume level at a predetermined level upon turn on from standby or at the level when last switched off.
    • Maximum volume – sets the maximum volume
    • Mute volume – sets the output level when muted, from 0 to any preferred setting
    • Digital output – to select between 48kHz and 96kHz settings for the digital output from analog inputs, as some devices in your system might not be compatible with the default 96kHz output.
  • General
    • Show inputs – choose between showing all enabled inputs or only those with signal
    • Front panel – to lock the front panel to disable all front panel controls
    • Auto dim – select the amount of time at which the front panel display will dim
    • LED brightness – set the level of display brightness for three specified dim levels
    • Standby settings:
      • Auto-standby – sets the amount of time without user interface action or signal from last selected source before the device automatically goes into standby
      • Wake up – enables auto-sense to wake up the device from standby upon detecting an input signal source
    • Factory reset – allows for the device to be returned to factory default settings

Amplifier Section

The amplifier section utilizes the new proprietary UFPD 2 power technology, providing immediate and sustained high power output with very low distortion, instantaneous rise time and absolutely linear amplification across the entire bandwidth resulting in a naturally fast, clean and agile sound over an ultra-wide frequency range and with exceptional headroom.

In UFPD 2 a new error amplifier circuit has been developed that does not affect the gain versus frequency curve and thereby the bandwidth does not have to be limited. This gives very low phase shift in the audio band and a larger closed loop bandwidth. Using a custom made output coil in the 2nd order filter error amplifier with the same loop gain results in feedback control across the entire audio band. It has been optimized to keep the loop gain constant in the audio band, which means it is actually lower at low frequencies than with UFPD but much higher at high frequencies. The result is even more linear amplification, with lower noise with UFPD 2, providing absolute “black” backgrounds from which music has a more holographic, three-dimensional, life-like character and richness.

Power Supply Section

Given the speed with which the UFPD 2 amplifier module is able to deliver power to the speaker a switch mode power supply was the only choice in that it allows for rapidly varying demand, providing much more stable voltage, with ancillary capacitive storage to meet peak transient burst requirements.

This newly developed Active Power-Factor Correction (APFC) converter is as much as 5% more efficient than past supplies, and comprises dual PFC converters 180 degrees out of phase from each other. AFPC is used to avoid input current harmonics, thereby minimizing interference with other devices being powered from the same source. This reduces the total current ripple and improves EMC (Electromotive Compatibility), while current ripple at the output of the PFC converter is also reduced, which decreases stress within the circuit for prolonged life. Additionally, the supply operates in what is called “transition mode”, minimizing switching losses and improving overall efficiency in delivering power to the UFPD 2 amplification module.

For more details see:

  • “UFPD 2 Amplification Technology Design Brief”
  • “Performance Benefits of UFPD Amplification”

Digital to Analog Conversion (DAC) Technology

In order to allow for playback of virtually any digital source with absolute accuracy and musicality, the I35 Prisma’s refined DAC stage recreates high-resolution sound that is as close as possible to the original source.

At the heart of this DAC stage is the new flagship of AKM’s Verita series, the AK4497EQ chipset, a premium 32-bit stereo DAC, incorporating the companies VELVET SOUNDTM technology, and capable of achieving -128dB (stereo) S/N and -116dB THD+N, while supporting up to 768kHz PCM and 22.4MHz DSD. This ability to handle higher resolution file formats will allow for the potential of future software upgrades.

The AK4497EQ integrates a newly developed switched capacitor filter “OSR Doubler” that greatly reduces sound degradation from noise shaping, achieving a flat noise floor up to 200kHz. An innovative design technique utilizing a symmetrical layout for the left and right channels prevents signal quality deterioration, and a 32-bit digital operation block provides full 32-bit processing.

Inputs include, four optical (Toslink), three RCA (SPDF), and one USB-B digital. The USB-B input allows playback of files up to PCM 768kHz/32bit and DSD256/11.2MHz

One RCA digital output is included, allowing for pass through of digital signals and the option to select 48 or 96 digital output from analog sources.

Connectivity and Control Technology Prisma

Prisma provides multi-room/multi-zone connectivity and control for playback of stored and streamed media, wired or wireless, all managed from any mobile device through a dedicated system control app. In addition to Bluetooth®, AirPlay, and Spotify Connect, Prisma features Chromecast built-in, a unique streaming portal allowing effortless direct connection to hundreds of streaming applications for the best possible performance and user experience.

Prisma App, in addition to the configuration settings control listed above, provides:

  • Switching of all inputs, analog and digital, stored or streamed
  • Volume control and input sensitivity adjustment
  • Customization of input options, including renaming
  • Multi-room multi-zone control between other Prisma enabled devices
  • Playlist and queue functionality from connected LAN storage devices
  • Wake up on cast signal


  • Digital – USB-A
    • Sample rates up to PCM 24/192kHz and DSD 128/5.6MHz
    • File formats: WAV, LPCM, AIFF, FLAC, ALAC, MP3, MP4 (AAC), WMA, OGG, DSD
  • Network
  • Wired/LAN Ethernet connection for wired network system connection
  • Wireless/WLAN – dual band wireless technology (WLAN IEEE 802.11 a/b/g/n and 802.11ac compliant)
  • Streaming
  • Bluetooth – connects Apple, Android, and Windows devices directly for playback of either streamed or stored content from the associated device with lossy compression. Given the wide availability of this technology and lower resolution capabilities, Bluetooth is an easy way to stream content for informal listening.
  • AirPlay – connects Apple devices over the WiFi network for playback of either streamed or stored content from the associated device with lossless compression. As a result, AirPlay has the capability of playing over greater distances than Bluetooth, and as the Apple Lossless Audio Codec is used to allow streaming quality up to CD quality (44.1kHz), is appropriate for more critical listening.
  • Spotify Connect – connects any device with the Spotify application over the WiFi network directly to that service, and allows for playback at the highest level offered by the required Premium service (up to 320 kbps).
  • Chromecast built-in – offering the greatest level of connectivity and control options:
    • The Chromecast built-in associated Google Home application connects the Prisma device to your WiFi network for casting hundreds of enabled music streaming services.
    • Because it provides a direct connection between the I35 Prisma and the preferred music service through the network, playback quality is limited only by the quality of resolution provided by that service, meaning the possibility of higher resolution playback from services like TIDAL HiFi and Qobuz (up to 24-bit/96kHz).
    • More than one device can be connected at a time, content can be cast to any Chromecast built-in device on the network, and control of all functions can be accomplished from anywhere within the network.
    • Automatic Prisma firmware updating through Google Home application.
    • Voice control though the Google Home speaker and Google Assistant is anticipated as that system becomes readily available.

System Building

The optional configurations offered are examples of Primare’s practical design approach extending not only to the individual components we make, but also to the system building options designed into each model. For example, if putting together a full-featured digital and analog system based on the I35 integrated amplifier platform, a number of pairing options. Two possible combinations are detailed below:

I35 + CD35 Prisma or CD35

Pairing an I35 Prisma and CD35 Prisma would mean redundant circuitry, with their similar DAC and Prisma components. This is one of the reasons that we offer the I35 analog only option. Not only does pairing the of I35 and CD35 Prisma avoid obvious redundancies between the two components and reduces overall system costs, but it also offers certain advantages for improved performance.

In part due to the industry standard ESS Sabre chipset employed in its DAC stage, the CD35 Prisma is able to provide subtly superior performance over the AKM chipset based DAC stage in either the I35 Prisma or I35 DAC. Additionally, the separation of the all-analog amplification circuitry in the I35 from the digital circuitry in the CD35 Prisma isolates those sections for lower noise floor and improved power supply delivery.

Note: the lack of Prisma technology in the I35 does mean that control of that unit through the Prisma app and multi-room/multi-zone functionality for I35 input sources is not available.

I35 Prisma or I35 DAC + DD35

For those who wish to have a single control and connectivity center, the I35 Prisma can be paired with the soon to be released DD35 CD disc drive. The DD35 is a transport only device, with digital outputs and no DAC stage, and is perfect to provide the best digital signal for conversion by the I35 Prisma or I35 DAC.
