Ultimate Series Headphone amplifier
Niimbus, the new high-end brand from the developers of the company Lake People.
Born from the experience of over three decades of Lake People development, as well as technically and visually raised the standards of the Violectric brand to a new, previously unknown level of quality, the name addition of the Niimbus devices is therefore logically "Ultimate Series". Devices with the Niimbus label stand for a special design, exceptional technology and uncompromising quality - of course "Handmade in Germany".
Niimbus US 4 represents the compromise further development of the recognized, high-quality headphone amplifier from Violectric. No compromises in circuit design, component and material effort were made during the three years of development to create a headphone amplifier with superior audiophile characteristics.
In conjunction with the oversized power supply and the associated high supply voltage, you get an extremely detailed and cleaned up sound, which plays absolutely relaxed in any setting and with any headphones and represents every nuance of the music.
The completely newly developed channel-separated and 100% analog amplifier circuit features hand-selected audiophile components and has been optimized for lowest noise and highest performance even on particularly low-impedance headphones.

WHY A HEADPHONE AMPLIFIER AT ALL ?
Is it not so that a headphone is only a small speaker and des- half only - if at all - a small amplifier needs? The headphone amplifier is a device for conditioning a audio signal with the purpose of adapting it to the special characteristics of a headphone? This sounds at first moment not particularly sensational and can also be done with little effort. However, it turns out, as with almost everything, that the devil is in the details and a certain amount of effort is necessary to have, if possible, one amplifier for all headphones.
