xDuoo TA-26 Tube Amplifier


Dang it.

Unfortunately, this product has reached its end of life. Thankfully, we have the perfect replacement in the xDuoo TA-26s.

Go all analog

This 500mW tube amplifier goes minimal where other amps get fussy. Simple RCA ins and outs, a volume knob, and a single-ended output are all you need to experience that classic tube sound. Tube amplification can pare back high-end shrillness and make vocals warmer, strings lusher, and bass meatier. Chrome guard rails and aluminum grilles add protection and a retro, sleek aesthetic.

Warm tube sound

Most modern solid state amps reduce distortion beyond the threshold of human hearing. Tube amps, on the other hand, add distortion. So why would anyone want one? Many people love the quality of the distortion that tube amps add. They can pare back some of the shrillness and extension of the upper-end and boost the mids and bass for an altogether warmer sound. 

Doubles as a preamplifier

Spread that tubey goodness around. If you’re tired of headphones, run the TA-26 to another amplifier or active speakers to bring the tube experience to the entire room. 

Tubes will roll

You’ll love being able to swap the stock tube for other tubes. Each tube has a different sound signature, adding or subtracting qualities like warmth, detail, and soundstage. It’s a fun way to play with the sound signature of a single amp, often for less than $30 a pop. Just be sure to find a reputable dealer of tubes before buying.
