“The EVO 400 provides this in abundance. Yet, where some tube components take this to an extreme, where it is so lush and romantic, dynamics and resolution suffer, the EVO 400 is a modern tube preamplifier. Most tube families have their own voice – the 6922/6DJ8 based units have one range of sound, those based on the 6H30 another, and the 12AX7/12AU7 still another. There are even a few designs based on the 300B tube.

Without going into an endless playlist of tracks, the EVO 400 is definitely rich in tonal saturation and contrast without over embellishing. Great recordings sound great, yet mediocre recordings sound pretty good, unlike some overly “tubey” preamplifiers, where everything sounds pretty good, yet nothing sounds brilliant. All of your favorite audiophile clichés apply to the sonic landscape painted by the EVO 400: big, broad, three dimensional. This is that “reach out and touch – it” feeling that tubes accomplish with ease.”
