Herb Reichert, Stereophile magazine USA
“Compared to the all-transistor Pass Labs HPA-1, the all-tube EVO 400 develops deeper, darker shadows, is more three-dimensional, makes more saturated tonal color, and has more eye-catching highlights. Its sound is thicker in viscosity than that of the HPA-1. Old-school tube aficionados would likely describe the EVO 400 as the clearest, fastest, most transparent all-tube preamp ever.”
