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.
