The 911 MK3 stereo power amplifier is our second-largest amplifier and one of the most powerful on the global market. The big wattage giant is considered to be one of the fastest power amplifiers in the world. Based on insights gained from the design of the much-acclaimed 909 model, it has been continually improved and developed and, as version MK 3, has already reached the third generation.

The 911 MK3 can continuously supply high current in a seemingly effortless manner, and can thus easily power loudspeakers with low impedance values and very complex loads. This amplifier is held in high esteem on account of its warm and detail-rich sound. In fact, the 911 is unsurpassed in its ability to decipher minute details at extremely high volumes on the best loudspeakers in the world.
