Enleum HPA-23rm Headphone Amplifier

Yes. The amplifier features dual output circuits—a voltage output for standard headphones and a current output for more demanding loads—ensuring it performs optimally across a wide range of impedance levels.

By eliminating negative feedback, the Ensence module prevents the phase distortion and timing errors often found in traditional designs. This results in a more natural, transparent, and immediate sound signature.

It is designed for both. While it features a battery for portable use, its robust aluminum chassis and reference-level performance make it equally suitable as the centerpiece of a high-end desktop system.

Yes. You can power the unit continuously using a USB-C charger or an external battery pack, allowing for extended listening sessions beyond the internal battery's capacity.

The 1/4" jack is connected to the current output circuit, which is ideal for driving high-performance headphones, while the 1/8" jack utilizes the voltage output circuit, which is better suited for standard headphones and sensitive IEMs.

Unlike traditional potentiometers that can degrade over time or cause channel imbalance at low volumes, the solid-state relay attenuator ensures perfect channel matching and signal purity across the entire volume range.
