TechHive

Power delivery of the Nickel amplifier with most loads is carried with ease delivering enough muscular sound to drive nearly any headphone on the market. A set gain value of the Nickel amp provides wider headroom than most smartphones and DACs can produce, but is low enough to maintain nearly the full dynamic range of volume from any source.

Armed with dual-voltage power supply system of Nickel produces dedicated power to charge and condition the inbuilt battery. Typical USB switching noise is eliminated with this design configuration, even when the battery is charging. Turning Nickel on and off is as easy as simply plugging in or unplugging the headphone jack connector.

Omnipotent portable sound.

Power Levels
Nickel will supply 150mW into 50 Ohms, 250mW into 32 Ohms, and 270mW into 16 Ohms and is stable into an 8 Ohm load making it ideal for nearly any headphone on the market. A fixed 3dB of gain allows higher headroom than most phones and DACs can generate.

Advanced Power
The internal battery feeds a dedicated dual-voltage convertor which generates dedicated ±5V analogue power rails. With this topology, USB switching noise is virtually eliminated and the listening experience is not compromised, even when charging the battery. Once turned on, battery level is constantly displayed on the integrated LED light pipe.

SmartSwitch System
The Nickel amplifier includes our patent-pending SmartSwitch system. Nickel has no on/off switch, only when both connectors are occupied will Nickel turn itself on. Turning off Nickel is as easy as unplugging either the source or the headphones.

Made in USA
All mechanical and electrical design efforts, including the layout of the 4 layer SMT board, was completed in-house with full custom tooling for all parts. Nickel uses the same rugged polycarbonate featured in Periodic Audio IEMs.
