Product details

Specifically designed for audiophile music lovers, Pioneer has developed this separate headphone amplifier with an integrated USB D/A converter. It supports nearly every connection type, from traditional RCA to 3- and 4-pin XLR/Neutrik connections. Whatever headphone cable you prefer, the U-05 guarantees the highest audio quality with its fully balanced circuitry. Additionally, advanced adjustment options allow for dramatic sound improvements.

The integrated USB D/A converter processes standard PCM signals at 2.8 MHz as well as DSD files at 5.6 MHz. With the Hi-Bit 32 function, you can upsample 16- and 24-bit signals to 32-bit quality, while the sampling frequency can be upscaled to as high as 384 kHz.

Der Pioneer besitzt einen sauberen Klang ohne große Patzer, wobei auch bei hohem Pegel kein Verzerren zu vernehmen ist. Zudem ist die Ausstattung recht üppig und die Verarbeitung des Modells sehr hochwertig. Leider lassen sich die Kopfhörerports nicht parallel nutzen und einen analogen findet man erst gar nicht...
