Yamaha Introduces a New, Superior Approach to Analog Amplifier Design.
More than forty years have passed since
the introduction and widespread
adoption of full transistor HiFi audio
amps during the 1960s. In the 1970s,
high performance, high output PNP-
NPN transistors made possible the pure
complementary configured power amps
that are now the main type of high
quality audio amps.
In recent years, however, digital
amps have become popular for their
high conversion efficiency and superior
uniformity of operating precision, as
well as for their lower weight, size and
heat production as compared to analog
amps. Which leads to the question,
which direction will audiophile-level
amps take in the future? Generally, two
possibilities are considered: continuing
to improve the traditional pure
complementary configuration analog
amps or working to achieve higher
sound quality from digital amps.
But Yamaha has selected a third
approach. This is an entirely new
floating and balanced power amp that,
by using power transistors with the
same polarity that are not
complementary, achieves complete
symmetry of pullable operation at the
output stage and permits full balanced
transmission (amplification) from the
input jack to just before the speaker
jack — a capability that has long been
the dream of audiophiles.
