Previously designed for the AMP-13R, the JET Bias was developed in order to maintain the highest possible efficiency while significantly increasing the performance of the output stage’s stability. Now the new JET2 Bias further enhances this performance, as it’s now tracking the bias “at all times” during the amplifier’s runtime.

Previously designed for the AMP-13R, the JET Bias was developed in order to maintain the highest possible efficiency while significantly increasing the performance of the output stage’s stability. Now the new JET2 Bias further enhances this performance, as it’s now tracking the bias “at all times” during the amplifier’s runtime. It now enables a ultra-fast correction of the bias and offset of the output stage, resulting in much more precise controls of the EXICON MOS-FETs of the AMP-23R.\u003c\/p\u003e\n\u003ch3\u003eADVANCED CONTROL AND POWER\u003c\/h3\u003e\n\u003cp\u003eThe AMP-23R employs the same transformer from the AMP-13R, but it employs an all new power supply circuit design, in order to provide higher current and less noise level performance. Now with new software architecture, a single MPU controls all the functions and circuits of the AMP-23R, resulting in significantly reduced number of the parts, and an improvement in efficiency throughout the circuits. Furthermore, the digital and analogue circuit section is now fully isolated from each other to minimize the interference, so that each section can perform at its best condition.\u003c\/p\u003e\n\u003ch3\u003eFLAGSHIP HEADPHONE AMPLIFIER\u003c\/h3\u003e\n\u003cp\u003eThe best possible headphone playback has been one of our core ambitions since the beginning of our company, and the AMP-23R follows this tradition. The Ensence Circuit allows a zero loss amplification factor change, which means one can fully experience every single detail and nuances of the music source direct to the headphone. With its 4 watts (at 50 ohms) the AMP-23R can easily drive any headphone available in the market.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Internal view of the Enleum AMP-23R technology highlights including the JET2Bias and MPU control.\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/enleum2_1.png?v=1681157143\"\u003e\u003c\/p\u003e\n\u003ch2\u003eDESIGN HIGHLIGHTS\u003c\/h2\u003e\n\u003ch3\u003e“ENLIGHTENMENT” OF DESIGN\u003c\/h3\u003e\n\u003cp\u003eOur philosophy of pursuing “simplicity” remains unchanged in the course of our journey.

The patent-pending volume indicator shows the precise volume position with a single “dot.” As the volume increases, the dot moves clockwise and vice versa. When the volume level changes, the “dot” changes size just like a moon phase. And with that visual indicator, one can instinctively and precisely recognize the volume level. All of this is mechanical, and the volume can easily be controlled by using the ergonomic knob and remote control.\u003c\/p\u003e\n\u003ch3\u003eBASE ISOLATION DEVICE\u003c\/h3\u003e\n\u003cp\u003eThe AMP-23R has optional anti-vibration feet, employing “Base Isolation Device” technology.

It offers our most powerful yet smallest high-end headphone amplifier in a uniquely designed casing. It has been created to provide no compromises and to support both desktop and portable listening for the discerning audiophile and design enthusiast. The clean design is enhanced by the minimalist user-interface, and it features Enleum’s renowned quality of design that make this amplifier a true work of art.\u003c\/p\u003e\n\u003ch3\u003eENLEUM DESIGN IDENTITY\u003c\/h3\u003e\n\u003cp\u003eOur design identity set by the AMP-23R is brought forward in the HPA-23RM. This clear design identity is inherited from the AMP-23R with the machined waveforms shared together with the faceted volume knob. The internal structure design effectively manages to transfer the powerful circuit’s high temperature to the chassis’ heatsinks. With such studies in minimalism, the HPA-23RM manages to acheive the similar output power of the legacy HPA-21, which is approximately four times bigger in volume.\u003c\/p\u003e\n\u003ch3\u003eULTRA PRECISION MACHINING AND FINISHING\u003c\/h3\u003e\n\u003cp\u003eThe minimalistic yet refined design is achieved through exceptional expertise. The design requires meticulous and sophisticated engineering methods, and must be machined with the mechanical tolerance only possible by world-class machining equipment and technicians. And the finish is created with the finest craftsmanship down to the last details. The chassis’ precision-machined waveforms of the heatsinks integrated down the sides of the amplifier create an organic visual friction.\u003c\/p\u003e\n\u003ch3\u003eERGONOMIC MINIMAL DESIGN\u003c\/h3\u003e\n\u003cp\u003eThe minimalist design embraces an intuitive user interface, offering a clean and clear layout of the machined casing with a delicate textural finish and a meticulous form. The internal layout and circuit placements also ensure the highest thermal efficiency. Enleum’s minimal design identity is especially represented in the ingenious construction of the bolts, placing and hiding them at the bottom of the product.\u003c\/p\u003e\n\u003ch3\u003eAWARD-WINNING DESIGN\u003c\/h3\u003e\n\u003cp\u003eThe Enleum’s design heritage is truly unique and recognized – being one of the very few manufacturers in the world to have won and continue to win numerous prestigious design awards. Ever since Enleum has been winning such awards from Red Dot and iF Design awards. The HPA-23RM has continued that tradition by winning the Red Dot Design Award 2022 and iF Design Award 2023.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Design_Highlights.jpg?v=1771975689\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Side view of HPA-23RMH\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/HPA-23RM_3-scaled_resize.jpg?v=1772207846\"\u003e\u003c\/p\u003e\n\u003ch2\u003eSPECIFICATION\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePOWER\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCurrent: 1 W (HPA-23RM) or 1.35 W (HPA-23RMH) \/ Voltage: 500 mW @ 30ohms (HPA-23RM \u0026amp; HPA-23RMH)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eINPUT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRCA and 1\/8″ Mini Jack (Analog)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOUTPUT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1\/4″ (Current Output) and 1\/8″ (Voltage Output) Headphone Jacks\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPERATION TIME\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUp to 5 hours (HPA-23RM \u0026amp; HPA-23RMH Voltage) \/ Up to 3.5 hours (HPA-23RM Current) \/ Up to 2.5 hours (HPA-23RM Current) \/ Continuous with USB C charger or battery pack\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDIMENSIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e116mm x 164.5mm x 22mm (w x d x h)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWEIGHT (NET)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e750g\u003c\/p\u003e","brand":"Enleum","offers":[{"title":"Default Title","offer_id":50552200364265,"sku":"HPA-23RMH","price":3500.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/enleum-hpa23rmh-main.png?v=1772209368"}],"url":"https:\/\/audio46.mom\/collections\/enleum.oembed","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
