Timing matters here because the 850 is an older Burmester monoblock, so condition and completeness count more than with a current model. At £818, this is a strong bargain against the recent used GBP cluster: it sits well below the £1,826 25th percentile and far under the £2,836 median, so the asking price leaves plenty of room for sensible restoration or servicing.
That makes it especially interesting for a buyer who wants classic Burmester build quality and authoritative, refined solid-state sound on a budget. These amps are well regarded for control, speed, and a properly grown-up presentation, and the low entry price is the real upside here. The only real caveat is practical: with an unknown-condition vintage power amp, confirm channel balance, noise, service history, and whether the pair is complete before treating it as a steal.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Burmester Audiosysteme traces its roots to Berlin, Germany, where engineer and musician Dieter Burmester founded the company in 1977, formally registering it as a GmbH the following year. Born from his frustration with a faulty preamplifier, Burmester repurposed medical electronics into the iconic 777 amplifier—named for its July 1977 debut—launching a legacy of precision engineering and unyielding quality standards. Handcrafted in Berlin ever since, the brand embodies Dieter's vision of technical innovation without compromise, even after his passing.
The company specializes in luxury high-end audio components, including preamplifiers, power amplifiers, integrated and multi-channel amps, CD players, D/A converters, phono preamps, surround processors, FM tuners, speakers, power conditioners, and accessories. Burmester also excels in turntables and cables, but its hallmark is fully DC-coupled designs and symmetrical balanced topology, first pioneered in the 838 phono preamp, delivering noise-free, distortion-minimal sound.
Positioned at the pinnacle of the high-end market, Burmester commands a global reputation for uncompromising musicality, timeless design, and bespoke craftsmanship, often rivaling or exceeding competitors in clarity and dynamics. Its prestige extends to automotive partnerships since 2002, powering elite systems in Bugatti Veyron, Porsche Panamera and Cayenne, Mercedes-Benz, and Ferrari models—proving hi-fi perfection transcends the home.
