Imitation Burmester 933 amplifier circuit amplifier 

The Burmester's equipment, sound is delicate and gorgeous, dynamic powerful, strong sense of the site is known, is now internationally recognized the highest degree of HI-END one of the high-end brands. Its nearly two years began to vigorously develop the Chinese market in the recent major audio show can see its shadow, each appearance will be one of the best, get a lot of Shaoyou recognition, its strength and Quality can be seen.

        The  Burmester 's  full range of post-amplifiers has a very low output impedance and a very high damping factor. Even with an output power of only 120W @ 4Ω, the 933 also has the perfect low-frequency control. For some "notorious" difficult to control's speakers can cope with, match well with "Dyn-audio" speakers, it is more outstanding performance, with all-conquering noble tone.
