It is one thing to engineer a product to be be built and reliable. It is another to design a thing to perform so beautifully that it stirs the soul. The Belles 350A Reference power amplifier is one of those rare instances where art and science combine to create a soul stirring marvel of engineering. The Belles 350A power amplifier reference sets an even higher standard of performance over the original Belles 350A power amplifier. Some of the changes are a completely new amplifier circuit topology. The new circuit has a complementary differential input stage using bipolar transistors instead of JFET transistors. The output stage uses new mosfet transistors with two times the power and current capability of the original Belles 350A. These transistors offer 64 amperes of current capability enabling the Belles 350A Reference to drive lower impedance loads. Also, the new output stage has no source resistors in the mosfet. This offers many benefits such as less coloration and many times when under heavy loads these resistors can fail. Another is better control and dampening of the loudspeaker load. The capacitance in the power supply has been doubled to stiffen it to improve its dynamics and noise reduction. The Belles 350A Reference amplifier has new wiring to improve its sonic performance. The balance stereo XLR inputs have been eliminated, but a single balanced XLR input has been added to allow the amplifier to be operated as a bridged mono-block. In this mode the amp can deliver 1 kilowatt into 8 ohms. The amplifier can be operated as a stereo amp with RCA jacks only for inputs. In this mode the Belles 350A Reference delivers 250 watts per channel into 8 ohms. The Belles 350A Reference is built using the finest components available: • gold-plated oxygen free copper binding posts • gold-plated input connectors (inputs can accommodate balanced and unbalanced signals) • oxygen free copper wire • fiber glass printed circuit board material • polypropylene capacitors • 1% metal film resistors • all power resistors are non-inductive ceramic The technology behind the Belles 350A Reference is impressive. Even more impressive, however, is the sound. Listening to the 350A Reference has been described as a memorable experience; you feel as though you are part of the musical performance.
