956 MK2 Power Amplifier

The stereo power amplifier 956 MK2 extends Burmester’s power amp portfolio consisting of the legendary 911 and 909, which have garnered international renown. The 956 MK2 offers an unusually high damping factor with an extremely short rise time to deliver large currents. Thus it combines loads of power with great dynamics and excellent musical timing. Its sound is marked by impressive spatial resolution and warmth. Internal wiring to supply power to the output stages and transfer signals to the speaker binding posts consists of 10 mm high-purity copper wire. This ensures that the high currents of the power amp are transferred without loss to the speakers. This amp coaxes airy sound images and bone-rattling dynamics even from loudspeakers with lowest impedances and complex loads.


Description

Since 1977 Burmester Audiosysteme has been manufacturing high-end audio components of unsurpassed quality. From the very beginning, the objective has been to create a perfect blend of highest-quality sound, technological innovation, and timeless design. Highly trained technicians assemble all Burmester components by hand in its Berlin factory. Because “Made in Germany” is a label that is taken very seriously by Burmester. Burmester’s research and development department constantly strive to not only keep up with the latest advances but to set its own trends and standards. From the first design sketch via a number of prototypes to the final product shipped from the Berlin factory: each component that bears the Burmester name has been developed in its entirety in-house. As an audio pioneer, Burmester has created a number of legendary components that have become icons of the high-end audio universe.

Burmester considers himself as a guardian and mediator of our musical heritage. The innovative technologies and the highest-quality parts used in the audio components ultimately serve only one purpose, namely, to give full access to the music. By listening to recordings of Elvis Presley, Herbert von Karajan or the Beatles you can bring the full spirit of music into your living room that no concert stage in the world can offer you anymore.

Bridgeable into mono operation by external mono adapters or internally at the factory
when ordering a pair of 956 mono amps
Bi-amping with the use of external bi-amping adapters
Balanced circuitry throughout like all Burmester components
Input stages in proprietary X-Amp technology (Class A)
Low overall negative feedback
Signal path completely DC-coupled, no distorting capacitors
High current delivery capabilities due to an oversized power supply
High damping factor enables effortless control of any speaker over the entire frequency
range, even at high frequencies
Stable at any load over the entire frequency range
Massive binding posts for connection of speaker cables (use only spade plugs!)
Remote on/off switching in connection with Burmester pre-amps and D/A converters with
variable output (remote control current: 10V DC)
A protection circuit outside of the signal path monitors the 956 during operation for overheating,
DC offset and overdrive.
