Size, drawn to scale

Both amplifiers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

One scale for both, aligned at the back panels the way they would sit against a wall, so the deeper one visibly stands further out.

Primare I15 needs about 16% more shelf area. Primare I15 is 53mm deeper - the measurement that decides whether a rack door closes.

Inputs and Outputs

The input and output selections that are offered is an important factor when comparing two amplifiers. Here you can find how the I/O selections of the Primare I15 MM and Primare I15 differs from each other.

Verdict

Siblings in Primare's I range, so they share a design and a house sound. It comes down to power, features and price.

Area	Better	Why
Power	evenly matched	Effectively the same output - 60W against 60W into 8 ohms is under 1dB, which is not an audible difference in loudness.
Grip on hard loads	evenly matched	Both behave much the same into 4 ohms - output increases strongly (100W and 100W).
Noise floor	evenly matched	Much the same signal-to-noise ratio (97dB vs 97dB).
Analogue inputs	evenly matched	The same number of line-level inputs (5).
Phono stage	depends	Primare I15 MM has a built-in phono stage (MM,MC) and Primare I15 does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way.
Room to grow	evenly matched	The same expansion options on both.
Shelf space	depends	Primare I15 MM takes up about 13% less shelf area (1200cm² against 1387cm²), and it is 53mm shallower, which is the measurement that decides whether a rack door shuts.
Price	B	Primare I15 costs less - $1,695 against $1,995 at list.

A Primare I15 MM B Primare I15
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

Neither runs away with it - they trade advantages. Let the "depends" rows and the speakers you already own settle it. If you play records, Primare I15 MM saves you buying a phono stage; if you do not, ignore that row entirely.

What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
