Know before you buy
The amplifier utilizes a unique circuit design that captures the harmonic richness and transparency typically found in Single-Ended Triode (SET) amps, while the EL-34 output tubes and robust power supply provide the current necessary to grip and control the low-end frequencies that often elude lower-powered SET designs.
Yes, the Torii Mk.3 is designed to drive demanding speakers with ease. It features a dedicated 4/8-ohm impedance switch on the chassis, allowing you to optimize the output stage to match your specific speaker load for better efficiency and control.
No, the Zen Torii Mk.3 is engineered with active filter voltage regulation to ensure silent operation. It is designed to have no audible idle noise or 'tube rush,' even when paired with high-sensitivity speakers.
The amplifier is designed to be highly responsive to tube rolling, allowing you to swap the EL-34 output tubes and input tubes to fine-tune the sonic character to your preference. This flexibility, combined with the onboard bass and treble controls, makes it easy to tailor the sound to your room and personal taste.
The Hazen grid modification reduces the tube's sensitivity to fluctuations in the power supply and signal path. This results in a more stable, transparent soundstage and improved clarity, particularly during complex musical passages.
The Torii Mk.3 uses standard RCA inputs and banana plug output connectors, making it compatible with most traditional stereo components. Note that it is a pure analog power amplifier, so it does not include a built-in DAC or remote control.
