Audiophile’s Dream: The Pinnacle of Balanced Audio

• The xDuoo TA-20 Plus Balanced Tube Headphone Amplifier takes audio performance to a whole new level. This fully balanced amplifier from input to output provides exceptionally clear sound, superior Crosstalk, high-resolution, and an impressive SNR.

Exceptional Power: No Headphone Left Behind

• The TA-20 Plus features 4-pin XLR and 4.4mm balanced headphone outputs with up to 2000mW of output power. It can easily drive headphones with impedances ranging from 6 to 600Ω, ensuring you get the most out of your high-end headphones.

True Tube Warmth

• Equipped with 5Z4P tube rectification and dual 12AU7 tubes, the TA-20 Plus delivers a warmth and softness to the audio that only tube technology can provide. Plus, these tubes are pluggable, allowing you to experiment with different brands and sound signatures.

Hybrid Powerhouse

• It combines the softness of tube amplification with the raw power of a Class A transistor buffer. This Tube + Transistor hybrid structure offers both finesse and force in the audio output.
