The HPA-23RM is our new reference dedicated headphone amplifier. It is designed for high-end desktop and mobile usage – hence 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 Bakoon’s 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-23R’s latest MOSFETs output stage with a simplified version of the JET2 Bias circuit. While its unique current output is a descendant of the HPA-21’s 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 Enleum’s reference circuits in a much smaller package.

Enleum HPA-23RM: the ultimate portable amp?

It sounds like Enleum has quite the reputation for producing high-quality audio equipment, particularly amplifiers. The AMP-23R integrated amplifier must have made quite an impression to garner such respect in the hi-fi and head-fi communities. With Soo In Chae's track record of innovation and success with Bakoon, it's no wonder that Enleum's products are so highly regarded. The HPA-23RM headphone amplifier seems to be the latest in meticulously crafted devices enthusiasts can't get enough of.
