Primare I25 Integrated Amplifier

I25 – Modular Integrated Amplifier

I25 is an award-winning modular full-size integrated amplifier featuring Primare's UFPD 2 amplification technology delivering 100 watts per channel, with the option of adding a digital-to-analog converter and Prisma network player modules at any time.

UFPD 2 — A New Standard in Class-D Amplification

The I25 is the latest iteration of Primare's iconic integrated amplifiers and among the first to use the new UFPD 2 power system — a radical reworking of Primare's award-winning UFPD all-analog Class-D technology. Providing 100 watts at 8 ohms of absolutely linear UFPD 2 amplification across the entire audible bandwidth, the I25 delivers naturally fast, clean, and agile sound with an unprecedented ability to bring music to life.

Modular Design — Built for Now and the Future

The modular design of the I25 allows for a sophisticated digital-to-analog conversion module (DM25) as well as a Prisma network player module (SM35) to be added at any time — enabling unprecedented system customization without replacing the amplifier itself. I25 continues a Primare tradition of delivering astonishing performance from compact and elegant integrated amplifiers for easy installation into virtually any living environment.

Modularity is a cornerstone of the Primare ecosystem. The I25 and I35 modular integrated amplifiers, the PRE35 modular preamplifier, and the CD35 CD player can all be updated with DAC and Prisma modules — either at the time of purchase or at a later date. This means your system can grow and evolve without compromise:

• Pair a CD35 with Prisma module with an I35 for clean separation of analog and digital stages
• Pair an I35 with DAC and Prisma modules with a DD35 CD transport for full multi-room and multi-zone playback of every source — analog or digital

The Look and Feel of Scandinavia

Every aspect of Primare's products — the way they look, the satisfying feel of the controls — contributes to the overall experience of living with the brand. Primare products exude the hallmarks of Scandinavian design: simple, elegant aesthetics with approachable and intuitive functionality. The signature Primare control knob is recognized throughout the industry for both its appearance and the way it feels in the hand as an input is selected or volume adjusted — lagom, not too much, not too little, everything in balance, proportion, and harmony.

Frequently Asked Questions

What is the Primare I25?
The Primare I25 is a modular full-size integrated amplifier using Primare's UFPD 2 all-analog Class-D technology, delivering 100W per channel into 8 ohms and 200W into 4 ohms. It features five stereo RCA inputs and accepts optional DAC (DM25) and Prisma streaming (SM35) modules, making it a fully upgradeable foundation for a high-end audio system. It is available at Vinyl Sound USA in Buffalo, NY.

What is UFPD 2 technology?
UFPD 2 (Ultra Fast Power Device 2) is Primare's proprietary all-analog Class-D amplifier topology. It maintains a consistent feedback loop gain across the entire audible bandwidth, resulting in amplification that is linear, fast, and musically natural — combining the efficiency of Class-D with the sonic character of the finest linear designs.

Can I add streaming to the Primare I25 later?
Yes. The I25 accepts the optional SM35 Prisma network player module, which can be installed at the time of purchase or added at any later date. This brings Spotify Connect, Qobuz, TIDAL, AirPlay 2, Bluetooth, and multi-room/multi-zone capability to the amplifier without requiring a system replacement.

Can I add a DAC to the Primare I25?
Yes. The I25 accepts the optional DM25 DAC module, adding high-resolution digital-to-analog conversion directly to the amplifier at any time — a key advantage of Primare's modular design philosophy.

How does the Primare I25 differ from the I35?
Both the I25 and I35 use UFPD 2 amplification and share the same modular architecture. The I35 is Primare's flagship integrated amplifier with higher output power and additional features. The I25 offers the same core technology and upgrade path in a more accessible configuration.
