Triode Evolution Integrated Amplifier
KT88 Class AB
Introducing a new generation of integrated vacuum tube amplifiers—ushering in a fresh era of usability and performance. Its name: EVOLUTION. This amplifier delivers user-friendliness never before seen in traditional tube amplifiers. With a stunning piano black finish and a large display, the design further evolves our premium series’ bold aesthetics. The core circuit is a KT88 push-pull design, guaranteeing an output of 40W + 40W, powerfully driving a wide variety of speakers. Experience a new world of vacuum tube sound with EVOLUTION.
Usability Beyond Conventional Tube Amplifiers
Remote Power Control Unlike traditional tube amps that require manual operation at the unit, EVOLUTION allows you to power the unit on and off with the remote control from your seat.
Premium Remote Control for Intuitive Operation The solid, machined aluminum remote provides easy control of power, volume, mute, and input source switching with a sense of luxury.
Large, High-Visibility Display The amplifier is equipped with a large, easy-to-read display that clearly shows volume level and input source, visible from anywhere in the room.
High-Quality Electronic Volume Control
With analog volume manufacturers in decline, high-quality components with minimal channel imbalance are becoming scarce. EVOLUTION is the first vacuum tube amplifier to adopt a premium grade electronic volume control that rivals analog sound quality, using the renowned MUSES series by Nisshinbo Micro Devices.
Simple Bias Adjustment
A built-in bias meter and adjustment knobs on the top chassis surface allow for easy, accurate bias tuning while viewing the meter.
Also Functions as a Power Amplifier
By switching the MAIN IN selector on the rear panel to the MAIN IN position, the input display changes to “POWER.” In this mode, the input selector and volume control are bypassed, enabling use as a standalone power amplifier.
Powerful Power Supply Guaranteeing 40W + 40W Output
Like our MUSASHI model, EVOLUTION uses a large toroidal power transformer. Rectification is handled by SiC Schottky barrier diodes, which offer excellent response and minimal losses. Together, they provide a stable and powerful power supply.
Optimized Input Signal Path
Using the electronic volume, the input signal routing has been redesigned for the shortest possible path, reducing crosstalk and improving channel separation to deliver crystal-clear sound.
