The xDuoo TA-68 is a fully balanced desktop tube headphone amplifier with independent volume controls for the left and right channels. Its signal path combines 5U4G tube rectification, 12AU7 voltage amplification, a four-tube 6C19 current buffer, and capacitor-coupled headphone outputs. Separate channel circuits and isolated transformer supplies maintain electrical separation from input to output, while balanced and single-ended connections support source equipment and headphones using XLR, 4.4 mm, RCA, and 6.35 mm interfaces. With a recommended load range of 60 to 600 ohms, the TA-68 is intended primarily for full-size, medium- and high-impedance headphones.
