xDuoo TA-20 Plus Balanced Tube Headphone Amplifier
Fully balanced and purely mesmerizing
Built on a fully-balanced circuit from input to output, the TA-20 Plus ensures an improvement in crosstalk, resolution, and SNR. This balanced architecture paves the way for a captivating, clear sound that envelops you in its richness.
2000mW of punch
Don’t let the size fool you. The TA-20 Plus is capable of outputting up to 2000mW of power, making it suitable to drive headphones with impedances ranging from 16 to 600Ω. Switch between the 4-pin XLR and 4.4mm balanced headphone output to get the most out of your headphones.
Tube Rectification: a vintage touch in a modern world
Equipped with 5Z4P tubes for rectification, the TA-20 Plus adds that much-coveted "tube" character to your sound. This means you're getting the best of both worlds: modern performance and vintage warmth.
Double the tubes, double the fun
The device uses two meticulously matched 12AU7 tubes for audio processing. This lends a unique warmth and softness to the sound, providing a fatigue-free listening experience. And hey, they’re rollable, so go ahead and switch them out to fine-tune your audio palette.
Get in sync
Nothing quite compares to watching a VU meter dance to the beat of your music. The TA-20 Plus includes a retro mechanical VU meter that not only gives you real-time output levels but also adds a bit of fun to your audio setup.
Class A Buffer: a perfect hybrid
By combining tube and transistor technologies in a hybrid amplifier structure, this Class A buffer amplifier offers a robust output that can easily drive many kinds of headphones, while preserving the nuance and subtlety in the sound.
Customized capacitance
For the true enthusiasts, we’ve got customized HIFI capacitors that enhance the audio output and provide pure, sweet sound quality.

Xduoo delivered again
"Firstly, shout out to apos for the stellar cs. This amp. . . so good. My first desktop tube amp. I was so impressed by the sound the portable xd05t, I felt i could trust xduoo to deliver again, and that they did. Stock tubes: still wowed me. The amp had that unique tube sound. But I got the ray tube bundle and swapped those in and soundstage and details, tighter better bass shined. Can't wait to roll the main tube to a aqua ii 274b."
Solid tube headphone amp, well reviewed, tip top build quality and sound for the money
"The xDuoo TA-20 Plus (X) arrived well packed and intact. It's got a solid high-quality look and feel, the exterior case and tube cage powder coating is well done. I like the tube cage design and its ease of removal and replacement. The use of speaker style banana plugs to hold the cage to the base is a clever touch. I ordered the Ray 12AU7 matched upgrade tubes and swapped them out immediately and began the "burn in" phase which isn't quite complete. The dual use volume knob and input setting selector has a good feel to it, and I like red color. The VU meter is a nice addition visually but practically it's not really required. I've used all 3 inputs, and the connections feel solid. I typically use the XLR input with my Focal Celestee and my Dan Clark Audio (DCA) Aeon 2 Noire headphones. The Focal are more efficient and require less input volume than the DCA. I'm not wandering into the minefield of how they sound, that's just a bear trap. I do have a comparison headphone amp in the mix with a Rupert Neve RNHP solid state. The "X" is warmer, a bit more musical and the bass is about even with the X versus the RNHP. I always wanted a tube headphone amp but didn't want to drop $2500+ on a McIntosh, Feliks, Auris, Cayin or Chord and I liked the look and reviews of the X. I tried to add a photo but despite 3 different attempts with different jpeg file photo, they would not load. I can say sincerely that the X I have looks just like the stock photos. For the price, the X is substantial and enjoyable amp, and I hope this current tariff nonsense does not prevent this well-built and nice sounding device from being as affordable as it is right now. Cheers!"
Joy in the Tube World.
"Build is wonderful, A joy to use. But it is a bit picky what it likes at least for me anyway. My sources are the Sound Devices 702 CF card recorder and Topping E70 Velvet and the computer I have win 11 music server client playing Tidal and Qobuz. I want to upgrade the Rectifier tube. Still undecided on the Pre drive 12au7 tubes. I need a bunch of time to really get familiar with the TA-20. I will say the Bass extension is not the greatest and a bit of glare in the mid treble, Midrange is very inviting, and the tonality pretty convincing. On my Hifiman Edition XS they do well. on my Aune AD-5000 quite tasty. The Focal Elegia not a good fit there. I think there is allot of potential here. I wanted this amplifier since I first saw it. I want to roll tubes when the time comes. But right now liking what I hear, but know there is so much more to give here."
"Great service. Quality product. Very happy."
Love the tube sound -
"Love the tube sound - very smooth. The fact that this unit is a hybrid, accepts balanced inputs and has the balanced output for my Denon AH-D7200 headphones are the reasons I bought it. It has plenty of power to drive the headphones and bring out the detail. I have not noticed any sibilance with this combination. Highly recommend."
one issue.....Sigh
"I got this with the upgraded Apos Ray tubes. I don't think it really needs them. It sounds great works well with my Aune Ar5000 and Sivga 023 headphones. Has a good warm tube sounds but the impact speed of transistors. my only issue is that when you plug in your headphones it does not turn off the audio outputs to my Amps.. Luckily I don't really crank up the volume so it's just a nuisance."
Hooking up the amp was
"Hooking up the amp was very easy. I have it paired with a Cambridge Audio DAC Magic 200, and there are no issues there. The amp adds a little bit of bass, and it’s well balanced. The unit is beautiful when lit up, and the build quality seems really good. Glad I got it. And the customer service from Apos was great and helped me choose this product over some others."
Just wonderful
"Great sounding hybrid tube amp. The Apos Ray 12au7 is a huge upgrade. If want an even better, more holographic sound, upgrade the rectifier tube. My favorite so far is the 274b."
xDuoo TA-20 Plus & Apos Ray 12AU7 Matched Tubes
"Admittedly, I am not an expert, but I LOVE this amp and tube combination! I recently bought a pair of HifiMan HE1000SE Headphones and wanted to try them with a tube amp. I searched the online recommendations and found a few higher end amps that reviewed well, but I wanted an amp that had sufficient power for the HE1000SEs. None of the "higher end" amps had as much power as the xDuoo and the xDuoo's reviews were very complimentary of the amp, so I decided to purchase it (at one third to one tenth the price of the others). Well the combination of the xDuoo and the Apos Ray Matched Tubes is wonderful with my new headphones. I actually have a much more expensive solid state amp that I am now using only as a DAC to power the xDuoo amp. And with the power reserves the TA-20 Plus has, I only run it at 40 out of 100 on the volume scale, so there is plenty of additional headroom, if needed. This is a GREAT combination and I love the way my headphones sound out of the xDuoo/Apos Ray combo. I highly recommend the TA-20 Plus with the Apos Ray Matched tubes!"
