Primare I35 Modular Integrated Amplifier

The Primare I35 Modular Integrated Amplifier is a fully balanced, future-ready centerpiece for high-performance audio systems. Built around Primare’s powerful UFPD 2 amplification platform, the I35 delivers 150 watts per channel into 8 ohms with remarkable control, detail, and tonal balance. Its modular design allows you to start with analog-only functionality and add digital or streaming capabilities as your system evolves.

Key Features

• Modular Design: Available in three configurations—Analog Only, with DAC (DM36 Module), or with DAC and Streaming (Prisma SM35 Module)
• UFPD 2 Amplification: 150W per channel at 8 ohms, 300W at 4 ohms, with linear behavior across the full frequency range
• Balanced and Unbalanced Inputs: Dual XLR and triple RCA stereo inputs for flexible analog connectivity
• Custom System Building: Seamless integration with other Primare components including CD35, DD35, and PRE35
• Scandinavian Design: Understated aesthetics with tactile controls, machined chassis, and intuitive interface

Choose Your Configuration

• I35 (Analog Only): Core integrated amplifier with UFPD 2 power and full analog input/output complement
• I35 DM36: Adds the DM36 DAC module with ESS ES9068A chipset, full MQA decoding, PCM up to 384kHz, and DSD256 support
• I35 Prisma: Adds both the DM36 DAC and SM35 Prisma streaming module for full network playback and app control

All configurations share the same amplification stage and core architecture. The digital and streaming modules can be added later, making the I35 a flexible long-term investment.

UFPD 2 Amplification

Primare’s UFPD 2 technology is a proprietary Class-D analog amplification platform with ultra-fast signal tracking and linear output across the entire audible spectrum. With 150 watts per channel at 8 ohms, the I35 provides high current delivery and dynamic headroom for a wide range of loudspeakers. Despite its speed and precision, the sound remains smooth and natural, avoiding the sterility often associated with digital switching amps.

DM36 DAC Module

The optional DM36 digital-to-analog converter is a fully integrated module built around the ESS ES9068A chipset. It offers support for PCM signals up to 384kHz/32-bit, native DSD256, and full MQA decoding. The DAC also provides selectable upsampling for system tuning. Digital inputs include Toslink, coaxial, and USB-B for connection to streamers, transports, and computers. This module is included with the I35 DM36 and I35 Prisma versions.

SM35 Prisma Streaming Module

The Prisma module expands the I35’s capabilities with full network streaming. It supports AirPlay 2, Bluetooth, Spotify Connect, and Chromecast built-in, with Roon Ready support coming via firmware update. Multi-room and multi-zone playback is accessible through the Prisma app, which offers control over playback from NAS libraries, cloud streaming platforms, or mobile devices. The SM35 module is included in the I35 Prisma configuration.

Design and Modularity

Clean lines, tactile controls, and a compact footprint make the I35 visually unobtrusive and physically satisfying to use. Finishes in black or titanium give it a refined look that blends well in modern and traditional setups alike. Internally, the modular structure allows for easy upgrades and servicing, and it ensures your amplifier won’t be obsolete the next time your listening habits change.

The Listening Room Difference

The Listening Room is a third-generation, family-owned business. When you call or email, you're likely talking directly to Michael Hoatson, the owner. Mike is personally involved in every sale and takes the time to understand each customer’s system. We don’t push boxes. We offer real service, setup help, and delivery from someone who knows the gear inside and out. That’s not something you get from big online warehouses, and it’s why our clients keep coming back.
