Know before you buy
Yes, the AMP-23R is engineered for versatility. It provides 4 watts into 50 ohms for headphones and up to 45 watts into 4 ohms for speakers, making it capable of handling a wide range of demanding audio equipment.
The Ensence circuit utilizes a zero negative feedback design to eliminate the timing errors often introduced by feedback loops. This results in a faster, more transparent sound that preserves the natural texture and speed of your music.
The Gain Phase control is an MPU-controlled stepped attenuator that adjusts the gain directly rather than simply attenuating the signal. This approach maintains signal integrity and ensures precise volume adjustments across the entire range.
The ENLINK input is a proprietary connection designed for optimal signal transfer when paired with compatible Enleum components. It uses a BNC connection to bypass standard voltage-based signal processing for a more direct, high-fidelity path.
Absolutely. With a compact 230mm by 230mm footprint and a sleek, minimalist chassis, it is specifically designed to fit comfortably on a desk without sacrificing power or performance.
This open-box unit has been fully inspected and tested to ensure it meets factory performance standards. It arrives in excellent condition and includes the full 2-year limited warranty for your peace of mind.
