U-05


 U-05

Headphone amplifier with D/A Converter for easy and accurate reproduction of music files from PC via USB
It has finally arrived.
For the true audiophile, we have developed our first discrete headphones amplifier with USB-DAC. Supporting almost any connection type, from a traditional standard jack to 3- and even 4-pin NEUTRIK jacks, you can customise your cables as you please. Whatever headphone cable you prefer, the U-05 always guarantees high-grade audio thanks to its fully balanced circuit. Advanced tuning possibilities allow even more dramatic sound improvement.
