## Description

Compact tube headphone amplifier with stereo inputs, dual jacks, and innovative design for high-quality, transparent audio with amazing purity and clarity.

Review: A little gem - This little headphone amp is tremendous value for money. Not only does it sound really good it has no trouble driving the most difficult headphones with it's 1100 mW output. Quality can be improved by op amp rolling if you like to experiment. I replaced the ones in mine with the Burson Audio V5i which made a big difference in the sound quality while still keeping the total cost around £100.
Review: important!! adapters! - Good info for buyers new to headphone amps. There are two headphone jacks on the Douk U10. 3.5mm and 6.35mm. Yes you can buy adapters but even if they look bling, most of those adapters are bad quality (badly wired internally or a poor fit in the socket) and will cause a lot of noise on this amp (and other amps). You are best connecting with whatever the headphone comes with. If the headphone comes with a 3.5mm or 6.35mm connector then use that. If you really must connect with a 3.5 to 6.35 adapter buy a good one and not an unknown one. UGREEN do a decent cheaper one.

## Features

- U10 headphone amplifier with strong power: stereo 3.5mm AUX and RCA inputs, compatible with most audio source such as MP3, phones, computers, CD players etc.. Dual headphone jacks (3.5/6.35mm) output up to 1100mW, easily to drive all 18-600Ω headphones; U10 also can be used as a preamp to improve the sound quality for amplifiers or active speakers.
- Advanced design and HIFI sound: innovative built-in voltage boost circuit, U10 always works at a high voltage of 24V even only powered by DC 5V, the sound with deadly quiet background, amazing purity and transparency, accurate position and wide sound field, easy use and unrivalled sound are both achieved at the same time.
- Pluggable design with higher playability: 2PCS 6A2 tubes are adopted to soften and warm the audio, sounds real and natural, full and mellow, delicate and sweet. Both tubes and op amps are designed with pluggable socket, convenient for tube rolling, op amp upgrading and sound-shaping, different styles of sound can be enjoyed easily.
- Excellent manufacturing and most cost-effective: all metal case with good shielding, pure ceramic tube socket with antioxidant contact etc., U10 provides excellent sound and strong power for your headphones in such a mini size, specially suitable for the audiophiles who love listening to vocals, string music, light or classic music etc..
- Warm tips: 1. Not inlcude power adapter, recommend to use original high-quality power adapter (DC5V/≥2A ). U10 won't work normally if the current below 2A. 2. Inputs (3.5mm / RCA) and outputs (6.35mm/3.5mm jack) are connected in parallel, in other words, all inputs and outputs work simultaneously. Don't connect 3.5mm and RCA inputs at the same time, or else audio signals will be mixed.

*by S***N on 27 January 2025*

My setup: Denon DSD DAC, Schiit Sys, Schiit Magni +, Bellari EQ570, Douk Audio U10, Hifiman Sundara Closed Back, Sennheiser HD 569, Sennheiser HD 280, AKG Q701. Lossless FLAC and High Res Music including DSD 64. Audrivana Music Player for Mac. Mac Mini 2024. MacBook Air. Move over Schiit Vali, there's a new Budget Tube Amp in town. Yes, it's that Good. My older Tube Amp died and I researched until I concluded that this Douk U10 fits my budget without sacrificing on sound quality and I was pleasantly surprised. A 5V Power chord is a must, don't waste your time with a USB connection since it will introduce noise and will not reveal the true potential of this little gem. Warm up time for the U10 is about 15 - 20 mins. I was not getting the most of my Sundara Closed Back with my audio setup until I added a Bellari EQ570 and the Douk Audio U10 Tube AMP. My Sundara came to life since it needed a some EQ and a matching amp like the U10 and its now heavenly bliss listening to Lossless and High Res. music. The Sundara has bass to die for, this headphone is lush with perfect lows, mids and highs. I now understand why Hifiman headphones are so popular Don't be fooled by "Audiophiles/Audiofools". Get this little champ before it's discontinued for an another model. I plan to get a second one as a backup. This little champ is highly recommended but without an actual 5V AC power supply, it will be noisy. Its dead quiet with a 5V Power Supply sold right here at Amazon. Highly recommended.
