xDuoo TA-26S 6N8P+6N5P Vacuum Tubes HiFi Headphone Amplifier

About this deal

The xDuoo TA-26S is an upgraded version of the classic TA-26 tube headphone amplifier, adding a 4.4mm balanced headphone output alongside the standard 6.35mm single-ended socket. It is an OTL (Output Transformer-Less) design, suited to headphones with impedances between 60 and 600 ohms, delivering up to 500mW of output power with total harmonic distortion of 0.1% or less. Professional-grade resistors and capacitors contribute to a signal-to-noise ratio of 110dB, with a frequency response spanning 10Hz to 30kHz. An RCA line-out port on the rear and a front-panel volume wheel allow the unit to double as a preamp for active speakers or a power amplifier. The stock tubes can be swapped for alternatives, each bringing a different sound signature in terms of warmth, detail, and soundstage. The chassis is built from aluminium and weighs approximately 3.9kg, giving it a solid, premium feel with a sandblasted textured panel. This open-box example offers a cost-effective route into high-quality tube amplification for fans of higher-impedance headphones.
