Big drive, switchable tube/solid-state tone, fully balanced architecture.
PB6 employs four military-grade JAN6418 directly-heated pentodes in a fully balanced amplification layout, offering both TUBE and Class AB output modes. The internal 8.4V high-voltage battery pack and optional 12V DC-IN desktop power unlock near desktop-class dynamics on the go. With 3.5mm single-ended / 4.4mm balanced dual inputs and outputs, PB6 fits diverse front ends and delivers serious current for demanding headphones.
