Devices with the Niimbus label stand for a special design, extraordinary technology and uncompromising quality - of course "Handmade in Germany".
Niimbus US 4 and US 4+ represent the uncompromising further development of the recognized, high-quality headphone amplifiers from Violectric. During the three years of development work, no compromises were made in circuit design, components or materials to create a headphone amplifier with outstanding audiophile properties.
The completely newly developed channel-separated and 100% analog amplifier circuit has hand-selected audiophile components and has been optimized for lowest noise and highest performance even on particularly low-impedance headphones. In combination with the oversized power supply and the associated high supply voltage, you get an extremely detailed and tidy sound image, which plays absolutely relaxed in every setting and with every headphone and represents every nuance of the music.
