The I15 Prisma is a streaming integrated amplifier by Primare that delivers 60 watts x 2 channels into 8 ohms and 100 watts x 2 channels into 4 ohms. It was released in 2020. It is a 2-channel design using a Class D output stage. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC, so you can play digital sources directly with no separate DAC unit needed. The Primare I15 Prisma has an MSRP of $2,195.

Primare Integrated Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Primare I15 Prisma is rated at 60 watts RMS into 8-ohms. Primare provides this wattage at a THD (Total Harmonic Distortion) of 0.05% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 60 watts into 8-ohms (20 Hz-20 kHz) at 0.05%
- 100 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 97dB Signal to Noise Ratio

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Primare I15 Prisma is rated at 60 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the Primare I15 Prisma with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the Primare I15 Prisma Amplifier good for?
