Overview
The Primare SP25 Prisma is a high-end home theater preamplifier designed to deliver an immersive and high-quality audiovisual experience. This sophisticated audio-video processor combines cutting-edge technology with meticulous design to satisfy the most demanding cinephiles and audiophiles.
A Powerful Technological Core for Total Immersion
The SP25 Prisma is equipped with advanced audio processing capabilities, managing up to 11 channels of immersive sound. It supports the latest audio formats, including Dolby Atmos and DTS:X, enabling the creation of remarkably precise three-dimensional soundscapes. With its seventeen customizable input presets, it offers exceptional flexibility for configuring various combinations of digital and analog inputs.
The processor also integrates Dirac Live Room Correction technology, optimizing audio performance based on room acoustics. This feature ensures optimal sound reproduction, regardless of the listening environment.
Extensive Connectivity for Maximum Versatility
The SP25 Prisma excels not only in home theater applications but also in high-fidelity audio, thanks to its integrated Prisma streaming platform. This technology provides access to a wide range of online music services, including high-resolution platforms like Qobuz, Spotify, and Tidal HiFi.
The SP25 Prisma boasts impressive connectivity. It features four HDMI 2.0b inputs with 4K compatibility, five analog RCA inputs, a 7.1 multichannel input, as well as coaxial and optical digital inputs. For networking, it includes two Ethernet ports, Wi-Fi, Bluetooth, and a USB-A port. AirPlay 2 and Chromecast protocols are also integrated, offering great flexibility for streaming audio content.
Elegant Design Combined with Thoughtful Ergonomics
The SP25 Prisma showcases a sleek and elegant design, a hallmark of the Primare brand. Available in a silver finish, it blends seamlessly into any interior. Its compact dimensions (430 x 405 x 145 mm) make it easy to install in an audio-video cabinet.
The user interface is designed to be intuitive and user-friendly. The SP25 Prisma comes with the PRISMA C25 universal remote, capable of controlling not only the processor but also other Primare devices, both old and new. Additionally, the device can be operated via a mobile app, offering precise and personalized control of all its features.
Impeccable Sound Quality for Discerning Music Lovers
The SP25 Prisma does not compromise on pure audio quality. It incorporates two ESS9026PRO digital-to-analog converters, renowned for their exceptional performance. The analog preamplification section has been carefully designed, featuring an optimized circuit with high-quality components to ensure pure and detailed sound.
For stereo music enthusiasts, the SP25 Prisma offers a unique feature: two front left/right analog outputs for bi-amping the main speakers. This capability significantly enhances stereo performance, making the SP25 Prisma a truly versatile device.
Guaranteed Upgradability for a Long-Term Investment
Primare designed the SP25 Prisma with upgradability in mind. The processor is Roon Ready, with a free update planned for the future. This modular approach allows users to benefit from the latest technological advancements without needing to replace their entire setup.
Additionally, the Dirac Live acoustic correction, initially limited to frequencies below 500 Hz, can be upgraded to cover the entire frequency range, providing increased flexibility for room acoustic optimization.
