DOUK AUDIO T6PRO Hybrid Class D Amplifier TPA3255 JAN5725 Tubes Yellow

The Douk Audio T6PRO is a hybrid HiFi amplifier combining tube amplification and modern Class D technology to deliver a sound reproduction that is both warm, dynamic, and powerful. It combines two JAN5725 tubes operating under a high voltage of 100V for true tube amplification with a high-end TPA3255 digital amplification chip capable of delivering up to 2x250W under 4Ω (THD+N=1%), allowing it to efficiently drive a wide variety of 4Ω to 8Ω speakers. Compact yet particularly powerful, the T6PRO is suitable for both desktop HiFi installations and home theater or living room systems.

The T6PRO features versatile connectivity including a Bluetooth 5.1 input based on a QCC5125 chip compatible with aptX, aptX-HD, and LDAC, supporting audio streams up to 24bit / 96kHz, as well as two stereo RCA inputs and one 3.5 mm AUX jack input allowing multiple audio sources to be connected simultaneously. A 3.5mm pre-out output is also integrated to connect an additional amplifier, active subwoofer, or active speakers in order to create a 2.1 or multichannel system.

The device also benefits from carefully selected audiophile-grade components including WIMA, ELNA, and Rubycon capacitors, professional audio inductors, and fully sealed precision potentiometers to ensure excellent sound transparency and extremely low distortion of only 0.01%, accompanied by a signal-to-noise ratio greater than 102dB. It offers complete tone controls with treble adjustment at ±8dB / 10kHz, bass adjustment at ±6dB / 200Hz, as well as a Super Bass adjustment extending down to 20Hz with an amplitude of ±10dB to reinforce low frequencies and achieve particularly deep and impactful bass.

The T6PRO also stands out thanks to its imposing dual backlit analog VU meters integrated into a large single front panel offering real-time dynamic display of the audio level. Its CNC-machined aluminum chassis ensures excellent robustness as well as efficient heat dissipation, while its oversized speaker terminals guarantee secure transmission of high power levels. Powered by 24V to 48V DC, it measures 140 x 165 x 69mm for a weight of 1.4kg, offering an elegant, powerful, and particularly versatile HiFi solution.
