Primare I25 Prisma: 100 W per channel stereo integrated amplifier with DAC and network player
I25 Prisma is the fully equipped version of the I25 family: on the same modular platform it carries both the DM36 conversion module and the SM35 Prisma network module. Compared with I25 DAC it adds streaming, wired and wireless networking and the USB-A input; compared with I25 it also adds every digital input. A single unit therefore covers amplification, conversion and network playback.
Power comes from UFPD 2 technology, Primare's analogue Class D. The DM36 module uses the ESS ES9068A converter and accepts PCM up to 384 kHz / 32 bit and DSD up to DSD 256, plus upsampling choices and MQA handling. Prisma is the brand's set of network technologies: it manages stored and streamed music across several rooms and zones, controlled from a mobile device via the Prisma app.
