Video Introduction of the Enleum HPA-23RM Reference Headphone Amplifier : here

The HPA-23RM is our new reference dedicated headphone amplifier.

It is designed for both high-end desktop usage and mobile usagehence using R for reference and M for mobile in the product name.

Continuing our legacy in the headphone amplifier design with up-to-date technologies, the HPA-23RM follows in the footsteps of the AMP-23R and our other legacy products, such as Bakoons HPA-21 and HPA-01M.

The HPA-23RM contains two amplifiers in one package as it employs both voltage and current outputs. The voltage output circuit is directly inherited from the AMP-23Rs latest MOSFETs output stage with a simplified version of the JET2 Bias circuit.

While its unique current output is a descendant of the HPA-21s bipolar transistor based circuit, its modern design is even more refined with advanced technologies.

Furthermore, thanks to the technological advancements in the battery power supply design and efficient thermal design, one can now listen to Enleums reference circuits in a much smaller package.

TECHNOLOGY HIGHLIGHTS
Every critical component and circuit of the HPA-23RM work in harmony to provide the utmost headphone listening experience. The HPA-23RM shares the same circuits with the award-winning AMP-23R.

Yet the output stage design is new, incorporating ideas from the AMP-23Rs JET2 Bias circuit. It also employs the all new improved current output circuit from the legacy Bakoon HPA-21.

The HPA-23RMs novel power supply allows the headphone amplifier to be operated in R mode for full output power when powered by external power or battery via USB C. The M mode is for more efficient use, powered only by its internal batteries for portable use.
