Belles MB500 Mono Blocks

Dave Belles passion for pushing the boundaries of amplifier design has reached new heights with the introduction of MB500 monobloc amplifiers. Producing such exemplary performance from a solid state amplifier does not come easy. Many years of refining, rigorous testing and outright tenacity has paid off with aplomb. Listening to the Belles MB500 will tell you, that Dave Belles has created some very special indeed.

The construction of the Belles MB500 aids in providing a rigid structure to eliminate mechanical feedback vibrations. For example, the top and bottom covers are 6mm thick machined aluminium, the side panels are 9mm thick aluminium, and the front panel is 24mm aluminium. The enclosure is decoupled from its mounting surface with four custom Black Ravioli feet.

Gold-plated Oxygen Free Copper (OFC) binding posts and input jacks. Silver-plated Van Den Hul internal hook-up wire maintains the purity of the entire circuit path. Power is supplied via a massive bespoke toroidal power transformer. The class AB amplification circuit uses a complimentary circuit topology to ensure perfect symmetry and performance from the positive and negative signal throughout the unit. The input stage uses a complimentary differential amp input stage. The output stage uses 16 power mosfet transistors of the highest quality and specifications, capable of driving a wide variety of speaker loads. Unit distortion is virtually immeasurable.

Belles MB500's are very simple to put into words, "supremely effortless musicality" with an astonishing ability to captivate the listner for countless hours with utter true to life realism. From the most delicate special stringed nuance or electrifying guitar solo, to the mightiest orchestral crescendo. Belles MB500's are without equal in reproducing the 'true event' as it was captured in time. Performance of these amplifiers is nothing short of breath taking. One of the very select few audio components in the world that can convincing suspend belief!
