## Description

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. 3. Pluggable tube socket design, 6A2 can be replaced by the following models: 6J1、6ж1П、6AK5、6BC5、403A/B、5654、EF40、EF95、CV850、6J2、6ж2П、6AS6、CV2522、EF11/732、CV4011、6J3、6ж3П、EF96、CV848、6BC6、6AG5、 6J4、6ж4、6136、6BX6、6AC7、EF94、6AU6、6K4、6K5、6K4П、6BA6、6DA6、EF89/93、5749 4. U10 can easily drive all headphones even with high-impedance such as HD580/HD600/HD650 / K701/K702/Q701 / DT880/T70/T90 / SR225/SR325/RS1e etc. Parameters Brand: Douk Audio Model: U10 Audio input: 3.5mm AUX / Stereo RCA Audio output: 3.5mm / 6.35mm headphone jack Tube Model: 6A2 (2PCS) Op amp model: NE5532 (2PCS) Frequency response: 20Hz-30KHz Output power: ≥1100mW (32Ω) Matched headphone impedance: 18-600Ω Signal to noise ratio: ≥110DB Input voltage: DC 5V (≥2A) Working voltage inside: DC 24V Net weight: 200g / 0.44lb Package weight: 300g / 0.66lb Dimensions (W*D*H): 69*95*30mm / 2.72*3.74*1.18in (not including tubes) Package Dimensions (W*D*H): 132*85*90mm / 5.20*3.35*3.54in Packing List 1 × U10 Headphone Amplifier 2 × 6A2 Tube 1 × Acrylic Board 1 × USB to DC Cable 1 × User Manual

Review: 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 desertcart. Highly recommended.
Review: So it may be silly to be in love with a small tube buffer headphone amp but goodness this device is so fun and sounds so good. I just recently bought a good pair of headphones, Kiwi by Linsoul, and I tried a different headphone amp did not like it so I took a chance on this rather inexpensive device. I had a couple of improvements in the tube department so I added those listen to it for a few days and then added two new op-amps. Lme49720. They have a lot of clarity and they work beautifully with the tubes. Currently listening to Fleesh, a great Brazilian band and their tribute album to Marillion. Beautiful. Thank you Douk.
