Reviews & Resources
Manufacturer’s website: https://www.krellonline.com
In What Hi-Fi?, the Evolution 402 was praised for delivering "speaker-melting 400 W per channel into 8 Ω," with effortless control over even demanding speakers and a "mesmerising transparency" that reveals layers of detail in complex music such as The Rite of Spring.
According to Hi-Fi Critic, via TMR Audio, later production units elevated neutrality and consistency, pairing superb build and finish with power and current reserves that rival Krell’s top-tier 700 model.
On Audiogon, an owner review described the 402 as presenting music intact—“full of life and passion”—without leaning toward either a solid-state sterility or tubelike coloration, instead offering tonal accuracy, fine detail, and immersive dynamics.
