Overview
PrimaLuna EVO 300 Tube Preamplifier
Dual-mono tube design. Six 12AU7 tubes. Precision analog control.
The PrimaLuna EVO 300 is a high-end vacuum tube preamplifier built around a true dual-mono architecture, with separate toroidal power transformers for the left and right channels. Six 12AU7 signal tubes and two 5AR4 rectifier tubes form an all-tube design focused on low noise, musical detail, and stereo separation.
With five stereo RCA inputs, Home Theater Bypass, and two pairs of stereo RCA outputs, the EVO 300 offers the connectivity needed for a dedicated two-channel system. Premium components and a motorized ALPS Blue Velvet volume control complete the package.
