xDuoo TA-26s

High-Performance Tube Headphone Amplifier

• 500 mW output power
• Balanced outputs (3.5 mm and 4.4 mm)
• 6N8P and 6N5P tubes
• Also functions as a preamplifier
• Audiophile-grade resistors and capacitors
• Gold-plated RCA connectors
• Aluminum alloy chassis

All-analog design

This 500-mW tube amplifier embraces minimalism where other amplifiers seem overloaded. Simple RCA inputs and outputs, a volume control, a single-ended output, and a balanced 4.4 mm output are all you need to experience the classic tube sound. Chrome-plated protective strips and aluminum grilles provide protection and an elegant retro look.

What’s new in the “s” version?

The TA-26s is the second version of the model and features a balanced 4.4-mm headphone jack as well as a power switch on the back.

All in balance

Connect a balanced headphone cable to the 4.4-mm jack and enjoy a connection that is less prone to interference than typical single-ended cables.

Warm tube sound

Most modern transistor amplifiers reduce distortion below the human hearing threshold. Tube amplifiers, on the other hand, add distortion. So why would you want one? Many people love the quality of the distortion that tube amplifiers produce. They can slightly reduce the sharpness and extension of the highs and boost the mids and bass to achieve a warmer overall sound.

Serves as a preamp as well

Spread that glorious tube sound. When you’ve had enough of headphones, connect the TA-26s to another amplifier or active speakers to enjoy the tube experience throughout the room.

Tubes are making a comeback

This 500-mW tube amplifier embraces minimalism where other amplifiers seem overloaded. Simple RCA inputs and outputs, a volume control, a single-ended output, and a balanced 4.4-mm output are all you need to experience the classic tube sound. Chrome-plated protective strips and aluminum grilles provide protection and an elegant retro look.

All analog

You’ll love swapping out the stock tube for different ones. Each tube has a different sonic character and adds or subtracts qualities like warmth, detail, and soundstage. It’s fun to experiment with the sound characteristics of a single amplifier—often for less than $30 per tube. Just be sure to find a reputable tube dealer before making a purchase.
