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."
