Power Amplifier
The 911 MK3 power amplifier is a close derivative of the reference power amp 909 and is regarded as one of the quickest and most powerful amps in the audio world. Its strong performance is the result of the knowledge and experience gained during the design and manufacture of the much-acclaimed 909 power amp. The MK3 moniker indicates that Burmester’s second largest power amp has reached its third generation of refinement. With the distinctive appearance of the silver anodized fins of its heat sinks the 911 MK3 exudes power and elegance. It tightly controls any bass driver and proves that there is a lot of musicality in the bass line. Excellent spatial resolution, detail and musical warmth characterize the sonic signature of the 911 MK3.
With attention to detail.
Recognisable as a typical Burmester even from the very first glance, the 911 MK3 power amplifier makes use of characteristic design elements of the Top Line.
Design
The design of the 911 MK3 power amplifier represents the perfect blend of form and function. The silver anodized housing elements and aluminum cooling fins in typical Burmester design are recognized for their stylishness and timeless beauty. The fins work as perfect heat sinks and make certain that the power amp is able to pump out maximum performance on command without strain. The chrome plated triangle with the curved manufacturer’s signature on top of the chrome plated front trim leave no doubt that this is a genuine member of the Burmester power amp family. The lid with the large milled Burmester signature has proven so popular that it is now offered as an option for other company amps.
Handmade
Like all Burmester components the 911 MK3 power amplifier is hand-assembled in the Berlin factory. All parts and components that are used for Burmester power amps are measured and selected to very tight tolerances. This is considered necessary to ensure the best-quality build, reliable operation and value-retention over many years. The aluminum fins of the heat sinks, which give Burmester power amps their distinctive appearance, are manufactured by a Berlin supplier on especially developed tools. Most of the other components are also bought from local top-tier suppliers. This is the basis for Burmester to ensure uncompromising manufacturing quality and long-lasting reliability for which the brand is well known.

Burmester 911 MK3 — Reference Power Amplifier
The Burmester 911 MK3 is a high-power, exquisitely built stereo power amplifier that marries reference-class transparency with prodigious current delivery. As Anthony Kershaw noted in Audiophilia, its sound is effortless, uncolored and liquid, delivering micro- and macro-dynamics with near-limitless headroom. Imaging is expansive and precise, revealing width, depth and uncanny placement; bass is deep, controlled and exceptionally resolved. The MK3’s substantial 32 kg chassis, silver-anodized finish, laser-cut detailing and heavy-duty, color-coded binding posts underline its handcrafted construction and ergonomics. With bridgeable mono capability, bi-amping adapters and Burmester’s Class-A-X-Amp topology, it suits demanding loudspeakers and reference systems where clarity and control matter most. For collectors seeking a no-compromise power amp, the 911 MK3 represents a compelling, if premium-priced, statement piece.
Pros
- Extraordinary dynamics and headroom — effortless micro- and macro-dynamic control with very high continuous current delivery.
- Near-transparent, grain-free presentation with liquid detail and expansive, well‑defined imaging.
- Reference-level build and practical power features — handcrafted silver‑anodized casework, heavy-duty binding posts, bridgeable mono and bi-amp options.

Cons
- Premium price positions it firmly in the ultra-high-end segment — a major investment for prospective buyers.
- Binding-post design accepts spade lugs only, limiting connector flexibility for some installations.
- Reveals upstream weaknesses and can clip abruptly only under extreme overload—demands top-tier source and partner components for best results.

Dynamics
94/100
Reviewer repeatedly praises the amp's 'near unlimited, stable power' and 'ridiculous ease' with micro- and macro-dynamics, describing it as 'effortless' and able to place listeners 'foursquare into whichever venue the recording was made.' The review also notes a very large power supply (continuous peak current 40A), eight power transistors per channel, stability into any load and high damping factor — all concrete indications of exceptional headroom, control and current delivery for its power class.
Soundstage Imaging
93/100
The reviewer says the 'width and depth of many recordings’ soundstage was an education,' that 'each instrument was perfectly placed' and calls it 'Imaging personified' with live-like note placement. These statements point to exceptional channel separation, stable imaging and expansive soundstage even at varied levels.

Build Quality
92/100
Reviewer highlights handmade construction, a 'stunning, silver-anodized case,' laser-cut detail, high-quality internal parts (including proprietary silver wire), large binding posts and a huge power supply. The unit's substantial 32 kg chassis and bridgeable/bi-amping adapters plus solid engineering (eight selected output transistors per channel) support a high build-quality rating.
Value for Money
90/100
At roughly US$35,000 and offering 350W/4Ω stereo (770W/4Ω mono bridgeable) with a large power supply and reference-level control, the reviewer argues the performance justifies the premium — 'Is one note worth near US$29,995? I think Beethoven may have thought so' and calls it 'Very highly recommended.' The review references peer territory (Lamm and Levinson) for bass quality, framing the 911 MK3 as a justifiable high-end purchase in its class.
