Enleum HPA-23RM Headphone Amplifier: Unmatched Precision and Portability
The Enleum HPA-23RM stands at the pinnacle of headphone amplification technology, delivering an unparalleled listening experience through meticulous engineering and innovative design. Drawing from the acclaimed AMP-23R, this model incorporates its award-winning circuits but advances the output stage with groundbreaking enhancements.
Central to the HPA-23RM's performance is the JET2 Bias circuit, a direct evolution of the AMP-23R’s design, which optimizes output efficiency and fidelity. Additionally, the amplifier integrates the advanced current output circuit from the legendary Bakoon HPA-21, ensuring a superior signal-to-noise ratio and pristine sound reproduction.
Versatility is a key feature of the HPA-23RM. Its novel power supply architecture supports dual operational modes: “R” mode for full output power when connected to an external power source or battery via USB-C, and “M” mode for efficient, battery-powered portability. This dual-mode functionality ensures that the amplifier excels in both stationary and mobile listening environments.
The Enleum HPA-23RM is a testament to exquisite engineering and aesthetic finesse. As the smallest and most powerful high-end headphone amplifier in Enleum’s lineup, it seamlessly combines form and function in a compact, meticulously crafted casing.
The amplifier’s minimalist design not only emphasizes elegance but also enhances usability with a streamlined, intuitive interface. Each detail has been thoughtfully considered to ensure that the HPA-23RM is not just a piece of high-performance audio equipment, but a true work of art.
ENCENCE
The HPA-2RM begins with the Ensence module exactly like th3e AMP-23R. The circuit employs all discrete transistors with zero negative feedback and features an ultra-fast and ultra-wide frequency response. All these advanced Technologies are concentrated in the compact Ensence module, which takes and important role in the input stage of the amplifier. This allows our renowned lossless variable gain, so that one can fully enjoy the same performance at any gain or volume level
VOLTAGE AND CURRENT OUTPUTS
Unlike the HPA modules , the HPA-2RM separatly features MOSFETs for voltage outputs and bipolar for current outputs. The Voltage output transistors are precisely controlled by unique and simplfied version of the efficient version of the JET2 Bias Circuit. The Current output circuits share similarities with the HPA-21 but has bee improved with up-to-date circuit enhancements
SOLID STATE ATTENUATOR
The HPA-23RM employs advanced solid-state relays in the attenuator circuit and is proudly Enleum's first amplifier to enable more efficient and lower-noise switching. The AMP-23R's ultra-precision resistor network is carried over, and the same gain adjustment method and control software are applied for a wide range of headphones and IEM sensitivities.
For both audiophiles and design enthusiasts, the Enleum HPA-23RM delivers uncompromising performance and visual appeal, making it a centerpiece of any high-fidelity audio setup. Its advanced technology and sophisticated design make it a versatile choice for both desktop and portable listening, offering the ultimate in sound quality and style.
