The PrimaLuna EVO 300 Integrated is the high-performance model in PrimaLuna's acclaimed EVO series of vacuum tube integrated amplifiers.

Setting itself apart from entry-level models, the EVO 300 features instant remote-controlled switching between Triode and Ultra-Linear operating modes, allowing listeners to tailor the sound character to their musical preference on the fly.

Hand-crafted with point-to-point wiring using premium Swiss-made silver-plated oxygen-free copper wire, the EVO 300 utilizes six 12AU7 tubes in the preamplifier/driver stage and four EL34 output tubes. It incorporates PrimaLuna's proprietary Adaptive AutoBias system with individual tube status LEDs for hassle-free tube rolling (supporting KT88, KT120, KT150, and more). Connectivity is expanded with balanced XLR inputs, a dedicated Subwoofer output with Mono/Stereo mode switching, and an HT Bypass input.
