SPECIFICATIONS:

"In the early 80's an amplifier was considered good only if it had very low Total Harmonic Distortion (THD) figures. In order to obtain low THD, designers used massive overall negative feedback techniques. During this era, Victor Sima was the head of Sima Electronics Company where he developed a different approach to amplifier design; Amplifiers designed with low negative feedback.

The approach was to look at each stage of the amplifier as an individual amplifier, then reduce local feedback and extend the frequency response as much as possible. Listening test were used to optimise the local feedback current and voltage of each stage. After optimisation, the individual stages were connected together to form the whole amplifier. The amplifier then passed a series of bench tests with resistive and complex loads to ensure stability. This design approach didn't have the impressive distortion figures of amplifiers using overall feedback, but had more impressive sound quality, and for most audiophiles that is what matters most. Still today, this is a widespread design approach amongst many well-known amplifier manufacturers."
