Primare I35 Prisma silver

The I35 Prisma integrated amplifier is the latest version of Primare’s now iconic 30 series integrated amplifiers. It is the first to use the new UFPD 2 power supply system, a radical redesign of Primare’s award-winning fully analog UFPD class D technology.

Offering 150 W at 8 Ω of absolutely linear UFPD 2 amplification across the entire audible bandwidth, the I35 Prisma produces a natural, fast, clean and agile sound, with an unprecedented ability to bring music to life. In addition to balanced analog inputs, the I35 Prisma includes a full DM35 DAC stage allowing 768 kHz / 32bit PCM and DSD 256 conversion, as well as Prisma connectivity and control technology.
