Review: Small & wonderful tube headphone amp! - 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.
Review: 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!

### ⭐⭐⭐⭐⭐ Powerful little beast, recommended!
*by K***7 on April 5, 2025*

Pros: Excellent sound quality, lots of volume/power, makes all music sound a little warmer and sweeter, brings out details, less listening fatigue, good stereo separation. Packaged well, arrived in great condition. Build quality is great. Cons: No included power supply, only a USB to DC cable (I do not recommend to use a PC USB port (dirty /noisy power and often not enough amps), you WILL need to purchase a separate power supply or need to make sure the USB power source you are using can actually output the required amps and volts cleanly otherwise you will get issues with distortion or it just won't turn on, my power back could not supply the appropriate voltage/amps over USB A but could over USB C. Other comments: the little light up plastic insert is silly, and completely unnecessary, I would rather there be no led light at all, I may open it up and remove those LEDs. Also I sort wish it had a little cage or bars to protect the tubes from accidental damage or impacts, but that isn't a por or con just a opinion.
