Burmester 077 Reference Line Preamplifier

Burmester 077 Reference Line Preamplifier

The corner stone of the worldwide success of Burmester Audiosysteme was set in 1977 with the launch of the legendary 777 preamplifier. To celebrate its 30th anniversary in 2007 the company introduced another extraordinary preamplifier, the 077. Its self-adjusting phono stage can automatically compensate for any channel imbalances of pickup systems. The result is a more precise and extended soundstage. Additional attractions of this anniversary model are its X-Amp2 amplification stages and its control via the innovative BurLink technology. Its exquisite sound and versatile functionality are an homage to the world-renowned high-end icon 808. Operating the 077 is intuitive and does not distract from a relaxed listening experience. Its visual appearance bespeaks the typical Burmester design language.

Design
The Reference Line housing of the 077 preamplifier impresses immediately with the outstanding manufacturing quality of its solid aluminum enclosure. The 077 rests on a special base with carbon fiber damping. This insulates it mechanically from any distorting interference on its outstanding signal processing capabilities. As the ultimate upgrade Burmester offers an external power supply for the 077.

Handmade
In the Berlin factory the cutting-edge electronics of the 077 preamplifier are carefully married to the high-quality aluminum housing. The hand-assembled printed boards, the powerful X-Amp2 amplification stages, the XLR terminals and other hand-selected electronic components are expertly crafted into an audiophile work of art. The process of careful selection and assembly and thorough quality control also apply, of course, to the available optional output modules.
