Overview

Power amplifier

The 909 MK5 power amplifier is the largest stereo amplifier in the Burmester portfolio and one of the most powerful in the world. Its imposing presence, combined with its ability to deliver even extreme power, has established the 909 as an international reference. For years, the specialist press has hailed it as "the ultimate power amp." Materials and engineering ingenuity are taken to the extreme in this exceptional amplifier. A standout feature of the 909 is its extremely high damping factor, which, coupled with its ability to deliver high currents, allows it to effortlessly control any loudspeaker.

With its unwavering power supply, the 909 effortlessly delivers consistently high currents, driving even speakers with the lowest impedance values. Impulse response is virtually independent of the load. Thanks to its exceptionally warm and detailed sound, the 909 captivates even the most discerning music lovers. Its ability to reveal even the smallest details, even at extreme volumes with the world's finest loudspeakers, is unparalleled. Numerous awards from the international trade press impressively underscore this position.

Burmester 909's IMPRESSIONS

With attention to the finest details.

Easily recognizable as a typical Burmester at first glance, the 909 MK5 power amplifier draws on characteristic design elements of the Reference Line.

Design

The imposing appearance of the 909 MK5 power amplifier visually reflects the consistent implementation of the high-end philosophy. The massive heat sinks with their silver anodized fins are recognized worldwide as a defining characteristic of Burmester power amplifiers. They symbolize uncompromising power as well as refined, melodic sonic qualities. Design and function merge into a powerful unity. The other power amplifiers in the Burmester portfolio are inspired by this monument of amplifier design, both in terms of design and their superior sonic characteristics.

Handmade

Before a 909 power amplifier is completed and ready for delivery, it goes through a series of assembly stations at the Berlin factory. From the hand-assembled circuit boards, whose solder joints are meticulously checked before installation, to the selected transformers and the computer-aided measuring station, approximately 100 hours of manufacturing time are required – in addition to 7 days of testing with further intensive quality controls, culminating in a comprehensive final listening test under real-world conditions. This elaborate manufacturing process ensures that the customer ultimately receives a product that is exceptional in every respect.
