Triode Evolution Pre Vacuum Tube Preamplifier
The “EVOLUTION” vacuum tube integrated amplifier, released in February 2022, brought a significant leap forward to the world of tube amplifiers with its modern design, display panel, and remote-control functionality. This concept evolved further into the 30th-anniversary commemorative model “EVOLUTION 300 30th Anniversary,” and then expanded into the “EVOLUTION MUSASHI.” All three models are integrated amplifiers, but can also be used as power amplifiers via a simple switch. The EVOLUTION PRE was created as the ideal preamplifier to pair with those units when used as power amps. Of course, it also works beautifully with general power amplifiers, making it a modern and simple vacuum tube preamplifier that you can enjoy with various setups.
Simple, Modern Design of the EVOLUTION Series
The front panel features a clean, symmetrical layout with a large central display and power/selector and volume knobs placed on the left and right sides, respectively
Sleek, Sophisticated Black Hairline Finish with High-Quality Aluminum
The chassis boasts a robust and refined structure that combines a steel mainframe with aluminum plates, providing both durability and elegance.
High-Quality Electronic Volume Control and Shortened Signal Path for Inputs
This unit incorporates a MUSES series electronic volume control from Nisshinbo Micro Devices, known for high sound quality and precision. By placing the volume control near the inputs, the signal path is minimized, reducing crosstalk and improving channel separation—resulting in clearer, more accurate signal transmission.
Isolated Power, Input, Amplification, and Output Sections
Along with the shortened signal path enabled by the electronic volume, the separation of the power supply, signal input, amplification, and output sections effectively reduces noise and interference
Carefully Selected High-Quality Components
Key components that affect sound quality are carefully selected for their superior performance:
- MUSES series electronic volume control by Nisshinbo Micro Devices
- Large R-core power transformer
- Original polypropylene capacitors
Highly Visible Large Display
A clear, easy-to-read display shows the volume level and input position at a glance from anywhere in the room. The display brightness can also be adjusted via remote control.
Premium Remote Control with Excellent Usability, Including Power On/Off
The remote control, machined from solid aluminum for a weighty and luxurious feel, allows you to operate power on/off, volume adjustment, mute, input switching, and dimmer functions.
