Measured Parameters Parameters Review: Little headphone amplifier, big sound ! - I'm a music lover who never took the headphone road, but as a retirement gift, I got a nice pairs of B&W headphone. I used them with my cell phone for a few months and decided to get a headphone amplifier. The U10 had good review, the price was right and the opamp and tubes swapping was a big plus. The tubes were replaced with nice GE 5654 and the opamp replaced by some discret AKLIAM AK05 (need some extension). The result was so good that I bought some wired headphones, the Hifiman Edition XS. I now enjoy very much what I hear. I don't feel the need to upgrade the headphone amplifier. Note: with the tubes and opamp I use, the U10 is almost dead silent, no background noise. If you get a bad copy, just ask for a replacement, it worth it. 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. ## 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..
