Refining the Golden Age of Tube Amplification
Meet the xDuoo TA-66, a high-performance tube amp designed in the spirit of classical tube amplification. Employing retro engineering techniques like point-to-point wiring, the TA-66 provides a truly classic tube sound. But thanks to modern components and amenities like a step volume potentiometer and an aluminum alloy shell, it doesn’t feel trapped in the past. The result is an amplifier that delivers golden age velvety sonics with a contemporary sensibility.
Precise point-to-point wiring
Printed circuit boards, while convenient, can invite signal interference and complicate repairs and modifications. The TA-66 overcomes these problems with point-to-point wiring, a traditional engineering technique that ensures the shortest possible signal paths and minimal interference. By connecting each component directly with copper wires, the TA-66 significantly improves the amp’s reliability and ease of repair and modifications.
Step-by-step volume control: Perfect balance at low volumes
Say goodbye to left-right imbalance at low volumes. The TA-66’s step-by-step volume potentiometer ensures precise control, maintaining perfect stereo balance from whisper-quiet to room-filling sound.
Aux out preamp
With its aux out preamp feature, the TA-66 can serve as the heart of your audio setup, enhancing the sound quality of any amplifier or active speaker it's connected to.
Aluminum alloy shell: Solid and interference-resistant
The TA-66's solid aluminum alloy case and sandblasted texture panel aren't just about looks—they shield your music from external interference, ensuring nothing gets between you and your favorite tracks.

"An excellent entry point to vacuum tube headphone amps." -WaveTheory
"I really like the TA-66. It sounds rich and clear....I like the form factor and knob feel....It transcends fun-fi and is a legitimate piece of audio gear." -United States of Analog
“Definitely has a tube sound signature with bass emphasis, smooth mid presentation, and treble that isn’t nearly as sharp as a solid state amp. It’s a warmer presentation. Perfectly-priced. xDuoo hit this out of the park.” -No Theme Reviews
