Enleum AMP54R Amplifier
Out of stock
The AMP-54R is Enleum’s most ambitious project to date, representing the pinnacle of our engineering and design expertise. Its unique and advanced technologies, combined with its award-winning “design perfection”, make the AMP-54R a true statement in the audio industry.
From Enleum's Work in Developing the AMP-23R and HPA-23RM
From Enleum's work in developing the AMP-23R and HPA-23RM, they have made significant technological advancements, including the development of the JET Bias, their proprietary software-controlled bias system, the new “Class SA” operation along with a dual output mode option that allows you to adjust the output of the AMP-54R underpinned by a dual-mono power supply. The result is the Enleum “enlightened” sound with unlimited headroom to drive a wider range of speakers. A sound that puts let’s you look into the music and put a light on each note, string, reverb and sound in the recording and provides a textural 4D soundscape as long as the “material” is in the recording. A sound you can live with for “ears and years”.
Dual-Output Mode
The AMP-54R features the latest JET3 Bias circuit, which has enabled Enleum to introduce the innovative dual-output mode – allowing users to tailor the amplifier’s performance to match the specific characteristics of their loudspeakers:
- HV (High Voltage) Mode delivers the full output power of the amplifier, providing 115 watts at 8 ohms or 200 watts at 4 ohms. In this mode, you get maximum power delivery, making it suitable for speakers that require higher voltage to achieve desired sound pressure levels – providing a more “open and dynamic” sound quality.
- HC (High Current) Mode reduces the output power to 50 watts at 4 ohms and 100 watts at 4 ohms, but in return, it increases the output bias current much higher than the HV mode. This mode provides enhanced control for higher efficiency loudspeakers, improving dynamic response and transient handling – providing a more “intimate” sound quality.
JET3 Bias and Class SA
With their new JET3 Bias circuit, the new software algorithm now tracks and optimizes the output stage bias with more accuracy; resulting in improved performance and efficiency in any given condition. Furthermore, the increase in the output bias circuit’s stability translates directly to driving power, allowing the AMP-54R to drive a wider range of loudspeakers with ease.
Current-Based MC Phono Input
Not only with a love for vinyl, but a heritage with our legendary EQA phono preamplifiers, Enleum is proud to offer their proprietary current input phono preamplifier stage, which maximizes the performance of MC cartridges by using current signals. It makes the AMP-54R a complete analogue amplifier solution for the no-compromise minimalist high-end audio system.
The MC input operates with any low voltage MC cartridges, anywhere between 0.2 to 0.5mV and 5 to 20 ohms impedance. As it takes the output current of the MC cartridges, there is no loading calculation necessary. It just “simply” works.
