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. ### ⭐⭐⭐⭐⭐ Amp *by on Reviewed in Australia 11 July 2026* A very nice unit with a very big punch love it ### ⭐⭐⭐⭐⭐ Som analógico valvulado - o efeito termoiônico e a dança dos elétrons. *by on Reviewed in Brazil 12 May 2025* Embalagem excelente, entrega no prazo.
