About the Primare I25 Prisma

A sweet spot in the innovative Prisma lineup

Primare's I25 Prisma has most of amplifier power of their top-of-the-line I35 Prisma, as well as the identical DAC and network player, while costing significantly less. If you listen to mostly to digital music sources, the I25 Prisma and a good pair of speakers are all you need to discover — or re-discover — how compelling 2-channel listening can be.

A sweet spot in the innovative Prisma lineup

Primare's I25 Prisma has most of amplifier power of their top-of-the-line I35 Prisma, as well as the identical DAC and network player, while costing significantly less. If you listen to mostly to digital music sources, the I25 Prisma and a good pair of speakers are all you need to discover — or re-discover — how compelling 2-channel listening can be.

About the only thing the I25 Prisma lacks is a turntable input, and you can fix that by adding Primare's excellent R35 phono preamp. And if your system is based on conventional sources like a CD player, consider the analog-only I25, which lacks the DAC and network player.

Primare's Prisma network player does it all, and does it well

Prisma is actually a bundle of technologies that provides a broad range of network music player features and functionality. It makes it easy to discover, explore, and share high-performance music playback, whether the source is stored or streamed, wired or wireless. Whether you're listening to Spotify® or files from your NAS drive, the Prisma control app provides total system management from your mobile device.

The I25 Prisma also features Chromecast built-in, a streaming portal that lets you connect directly to hundreds of streaming applications. Chromecast built-In streams audio directly from the cloud, so you get the highest sound quality. It's even possible to enjoy high-res music (up to 24-bit/96kHz) from services like TIDAL and Qobuz. The I25 Prisma is also Roon Ready (firmware update required).

Prisma is simply one of the most complete and well-thought-out network players we've seen. And the built-in high-performance 32-bit AKM DAC presents virtually any digital music source with a level of clarity and detail you may not have experienced before.

Primare's refined Class D amp technology

The I25 Prisma delivers 100 watts per channel into 8 ohms, and doubles that to 200 watts per channel into 4 ohms. How can an amp of such modest size and weight generate so much power? Primare's Class D amplifier technology. Compact, cool-running Class D amps are known for providing loads of instantaneous current with extremely low distortion, but some audiophiles felt that earlier Class D designs didn't sound as rich and dimensional as the best conventional amps.

Primare has been refining their Class D technology for over ten years, resulting in their latest UFPD 2 (Ultra Fast Power Device) amplifier module. This module is actually a balanced configuration of four discrete amplifiers — two per channel. It allows the I25 Prisma to produce concert-level dynamics with most speakers — even power-hungry 4-ohm designs.

No matter what kinds of music you listen to, you'll find the I25 Prisma's sound to be fast, clean, and agile. Reviewers also frequently praise Primare's Class D amps for sounding unusually smooth and refined.

Stylish sound from Scandinavia

Founded in Sweden in the mid '80s, Primare relies on a talented team of designers to create its innovative high-end audio components. Among audiophiles, their equipment is admired both for its exceptional sound quality and its elegant appearance.
