Bakoon AMP-51R


“One of the finest integrated amplifiers we’ve ever heard”

SKU BAK-A51 Category

The AMP-51R is Bakoon’s next generation flagship amplifier, born from years of experience and expertise in SATRI Circuit technology.

With their top-of-the line SATRI-IC, MPU Controlled Stepped Attenuator, Zero Set Bias technologies and all new output stage topologies, the AMP-51R takes amplification to a whole new level.

Precisely designed and machined aluminium cases ensure both beautiful aesthetics and functionality, with internal copper heatsinks and a remote controller. It is designed to be one of a kind and a masterpiece. It sounds like nothing you have experienced before, so much more of the “Enlightenment” of the Bakoon sound.

Imagine the perfect amplifier you’ve always been dreaming of, the AMP-51R is even one giant step beyond that dream – it’s simply staggering.


All new flagship circuit – The AMP-51R uses Bakoon’s top of the line SATRI-IC-UL and the latest generation bias control circuit with a more stable current source circuit which enhances the output stages’ performance. The circuit is further enhanced by greatly reducing the signal paths and interference between components.

The latest high power MOSFETs from EXICON are implemented together with the exclusive driver circuit which enables more stable output stage performance.

Complete control – An all new control circuit contributes to the AMP-51R’s stability by automatically protecting itself from AC input changes, DC output and high temperature. It also detects voltage fluctuations and controls each power supply accordingly, so that the amplifier runs from stable power at all times.

An OLED display shows the current status of the AMP-51R, and it is operated by two hidden knobs under the front panel or a remote control unit.

Output power – 100 watts in Stereo, 250 watts in Mono (8 Ω, 1 kHz)

50 stepped precision attenuator unit – The MPU Controlled 50 Stepped Attenuator is implemented for the first time in Bakoon’s amplifier, with only the best available high precision resistors with 0.1% tolerance and 25 PPM/°C temperature coefficient.

The new attenuator circuit ensures the best possible channel balance and signal purity.

Extreme mechanical engineering – In order to transfer heat from the circuits more efficiently, there are two CNC machined copper heatsink blocks inside. Also, various heatsink patterns are machined throughout the exterior surfaces.

The case itself is stabilized by three isolation feet, designed and positioned from meticulous calculations for the best anti-vibration performance.

Ultra low noise power supply – Three separate power transformers are used for input stages, output stages and control stages. For the first time in a Bakoon amplifier a custom made transformer from Plitron delivers the lowest possible noise level.

The power supply circuit also employs a separate ultra low noise regulator circuit to provide reliable power to the AMP-51R’s high precision circuits.
