The I25 is a modular integrated amplifier that blends Scandinavian design minimalism with high-end performance. Delivering 100 watts per channel through Primare’s UFPD 2 Class-D amplification, the I25 offers a transparent, fast, and refined sound across the entire audible bandwidth. Its modular design supports both an analog-only configuration and a fully equipped variant that includes the DM36 DAC and SM35 Prisma network player. This flexibility makes the I25 a versatile centerpiece for any two-channel system, equally suited for digital streaming, vinyl playback, or pure analog setups. Key Features UFPD 2 Amplification: 100W per channel into 8 ohms using Primare’s proprietary Class-D topology for wide-bandwidth, low-distortion power delivery. Modular Design: Available as analog-only or with optional DM36 DAC and SM35 Prisma network streaming modules. Balanced and Unbalanced Inputs: Five analog stereo RCA inputs and a full set of pre-out and line-out connections. Fully Balanced Circuitry: Engineered for ultra-low noise and signal integrity. Refined Scandinavian Aesthetics: Brushed aluminum faceplate, tactile controls, and an intuitive user interface. Expandable Platform: Seamlessly integrates with other modular Primare components, including the I35, CD35, and DD35. UFPD 2 Amplification: Clean Power, Complete Control At the heart of the I25 is Primare’s UFPD 2 amplification technology, a thorough reengineering of its original UFPD platform. Designed as a fully analog Class-D amplifier, UFPD 2 delivers 100 watts per channel into 8 ohms (200W into 4 ohms) with exceptional speed, linearity, and bandwidth. This ensures tight bass control, an expansive soundstage, and dynamic accuracy even with demanding loudspeaker loads. The result is a presentation that feels both natural and authoritative—ideal for listeners seeking resolution without harshness. Advanced Modular Technology for System Customization The I25 offers remarkable flexibility thanks to its modular design. You can choose between the analog-only version or a variant equipped with both the DM36 DAC module and the SM35 Prisma network player, allowing you to tailor your system to your exact preferences from the start. DM36 DAC Module: A full-featured digital-to-analog converter stage supporting up to PCM 384kHz/32-bit and DSD 256, with optional upsampling and MQA decoding. With galvanically isolated USB, optical, AES/EBU, and SPDIF inputs, it ensures pristine digital playback. The DM36 also enables WiSA wireless speaker compatibility, a rare feature in high-performance integrated amplifiers. SM35 Prisma Module: This award-winning streaming and multi-room platform adds wireless connectivity via AirPlay 2, Bluetooth, Spotify Connect, Chromecast built-in, and Roon Ready* support. Stream directly from nearly any app, control playback via voice or the Prisma app, and enjoy seamless multi-room audio across your network. This modular architecture not only future-proofs your system but allows seamless integration with other Primare components such as the DD35 or CD35. Whether you start with a fully equipped unit or expand later, the I25 adapts to your evolving audio setup with precision and versatility. Scandinavian Craftsmanship: Form That Follows Function Every Primare product reflects the Swedish concept of “lagom”—not too much, not too little. The I25’s minimalist design and thoughtful ergonomics make it an elegant fit for any listening space. Its signature control knob and intuitive layout ensure easy access to essential functions, while its solid chassis and internal architecture are built for long-term performance and low noise. Whether on display or tucked away in a rack, the I25 maintains a refined presence that matches its sonic abilities.
