Douk Audio U10 Mini Vacuum Tube Headphone Amp Amplifier 3.5mm 6.35mm for PC – High Fidelity Stereo Preamp for Home Speakers & Hi-Res Audiophiles

just about any sound you send through it will sound better!
having worked as a professional sound design and music composer in video games for 20+ years, i was a bit skeptical that for the low price (about $45) this device wouldn’t do much or sound decent at all. but honestly, afaikt so far just about everything i’ve sent through this sounds better! warmer, more rounded (especially the digital synths), slightly fuzzy around the edges (in a pleasent way). obviously if you send a crappy quality mp3 or internet streaming(usually low fi 128kbps) this won’t improve garbage compressed audio much. but if you have .wav or .flac, this will surely add something special when listening to those lossless quality files. tbh, i feel i could run my stems or mixes through this during a mixing session and get a really nice tube drive sound. for certain personally projects i feel i could even run the masters through this to add a nice ‘little something extra’ analog, since i tend to work mainly ‘in the box’.ive even been able to power this via the usb c(with a 4x usb a hub) from my laptop and then fed audio from the same laptop through this. there was only a subtle ringing tone when i turned the volume all the way up. but i just crank the output volume on the laptop and kept the volume knob on this tube amp down, and the ring is not noticeable at all. ymmv there, as i read some others got terrible noise when they tried this kind of setup.i love that it’s usb powered and you could easily take it on the road. the tubes sticking out do seem quite fragile obviously, and get a bit hot (probably normal behavior) so im aiming to be extra careful if i need to pack it or move it after heavy use, by letting it cool down completely first.overall id say this thing is a great deal and pairs will with my koss pro4aa’s. sounds quite warm and lovely and has a nice look and feel (the volume knob is smoooth). really glad i bought it!

ABSOLUTE BANGER
This piece of hardware is the goofiest little dude. It’s got no business sounding that good with a chassis that small. Truly killer for a desktop application or just general use with a record player or whatnot. Has become my absolute favorite little guy. Highly recommend lows are defined, highs punch through the clutter and mids lack the muddling they usually get on tube equipment. If ur thinking about it… Just buy it. So worth it.

Fun and cheap headphone amp. Plus it comes recommended by the Scientific Audiophile. Whoever he is.
Tubes are a little hard to push into place. I was worried I would break them given the amount of force I applied. And I’m still not sure if they’re installed correctly. Otherwise, I’m enjoying this little headphone amp a lot – great sound and has lots of volume. (I barley push them past the lowest setting as the headphones I’m using (Sony XM4) are easy to drive.)

Sounds perfect
This sounds great — using digital out spdif optical from my PC’s onboard realtek sound card to a cheap ~$13 Prozor DAC (also found on amazon), 3.5mm in, and out to my DT 770 Pro (80 Ohm) headphones. I’m using the external DAC instead my onboard’s DAC because I get some noise unless I do, but that has nothing to do with this amp at all — it’s the onboard realtek’s fault.Anyways, using optical spdif, the external DAC, Windows volume at 100%, this amp’s volume knob turned ALL the way up, and playing a track with silence — I hear zero line noise. With my EQ that has -6.5db pre-amp, and foobar2000 at -8db, turning this up past around 2 o’clock (where 12 o’clock would be the halfway point) would make me deaf pretty quick. Dunno how this handles higher Ohm headphones, but it’s drives 80ohm with PLENTY of headroom.Throwing some good vintage RCA 6au2 — sounds 99.95% the same (certainly no better) as the 6au2 tubes that come with it, so don’t bother with doing that.

Super Sound, alles hochwertig, super Optik, wer Röhren mag, absolute Kaufempfehlung
