Mono - Stereo Power Amplifier MBL 9011

The 9011 features everything that its smaller sibling, the 9008 A, has to offer – and then some. It begins with the delivery of more long-term power output and short-term current distribution, a feat achieved by way of three groups of eight output transistors each, eight electrolytic and charging capacitors, plus a third 400VA toroidal transformer to further increase charging speed and facilitate speaker load matching. Total control. Its heft in power is matched by a total component weight that eclipses an anchor on a luxury yacht. This 95 kg (215 lbs) colossus unleashes up to 50 amps of peak current and a pulse output of up to five kilowatts into a 2 Ohm load. The result? Despite the amplifier’s huge on-board power reserves, the 9011 delivers a studio-clear, non-electronic sound that hearkens to the golden analog age of musical purity. Unrelenting, even when powering low-impedance speakers, the amplifier presents pitch-black backgrounds and remains nimble and tight across the audio band, with blistering high-frequency transients, a rich and airy three-dimensional midrange, and a fully extended, well-dampened bottom-end. The MBL 9011 delivers the full spectrum of front-row, concert-like sound reproduction from your cherished music.


The ... tremendous 9011 power blocks, each weighing 90 kilograms,
represent just about the strongest that the hi-fi market has to offer.

Silent Reserve - Switchable Mains Transformers

The commanding 9008 A Reference Line power amplifier houses two toroidal transformers, whereas the 9011 has three, which can be switched on or off using a rocker switch on the rear of the chassis. The additional network transformers do not change the power output, but they favorably influence the sound impression and contribute to speaker load-matching. In the two-pack and even more effectively in the three-pack, the huge output capacitors are charged even faster and bring the speakers even closer to their peak potential. The sound is inspiring, extremely precise, fluid and natural. With fewer transformer windings, every music performance sounds live, active, and buoyant. With the option to fine tune the use of the transformers, the sound of the 9011 can be flawlessly adapted to different room conditions or optimized to the speaker's impedance curve.

The 9011 at a glance

  • Designed as a differential-balanced mono block amplifier, but can also be used as a stereo power amplifier in single-ended mode
  • Combination of Class A and Class AB amplification
  • Direct, high-precision signal processing by Direct Push-Pull technology
  • Unparalleled resolution of the finest musical nuances
  • Sound tuning/speaker impedance matching via two separate switchable power transformers
  • Two separate power input sockets
  • Extremely quiet signal ground by means of fully symmetrical signal flow from the input to the output
  • Power transistors located on a foundation of vibration-impeding solid copper
  • Compensation of all transistor non-linearities by means of unique Isolated Gain Cell circuit
  • Sixteen output devices deliver 840 watts of musical power (at 4 Ω) with an output current of 50 amps, maximum pulse power: 5,000 watts (at 2 Ω)
  • Six high-quality, in-house manufactured solid copper connecting terminals with the option of bi-wiring
  • Weight of 95 kg (215 lbs)
