The STASIS 8.0 stereo power amplifier represents the consummate balance of
brute force and nuanced control. To some, its appearance may suggest
an obsession with solidity and power. Its credentials in these areas
are formidable - and readily apparent on first listen.
High current capability, the importance of which in providing bass
extension and tight control of the loudspeaker is often glossed over,
is a quality that STASIS amplifiers deliver in real-world terms. The
STASIS 8.0, for example, is able to provide staggering amounts of
continuous current, enabling the 8.0 to drive the most demanding and
power-hungry loudspeaker loads, without strain or stress. In this
regard, not surprisingly, it is the heir to Threshold's legacy of
high current, no-holds-barred performance. and is arguably
Threshold's best stereo power amplifier ever.
But the truth is that high current is only part of the story.
The most noteworthy aspect of a STASIS amplifier's performance is its
sweet, gentle, and honest reproduction of musical subtleties. In this
respect, its ability to reproduce transient attack and to resolve
complex musical passages surpasses that of even our acclaimed
T-series and e-line. The STASIS 8.0 delivers high current, employs
minimal feedback, and uses an updated version of the front-end of the
famous T200 along with the latest incarnation of our classic STASIS
output topology. As with all STASIS products the amplifier is
direct coupled input to output, with no capacitors in the signal
path, utilizes close tolerance metal film resistors and matched
JFETs, and employs a substantial power supply built around a massive
custom toroidal power transformer, with separate power reserves for
voltage and current gain stages.
The carefully balanced integration of the best elements of classic
Threshold products, together with-the fruits of constant
investigation and innovation specifically for this new generation of
STASIS amplifiers, means that it is no longer necessary to choose
between power for dynamic contrasts and resolution of fine inner
detail. Dynamic range and subtle shadings are rendered with an
unmistakable sense of truth and fidelity to the source that is indeed
remarkable. The STASIS 8.0 has raised Threshold's acclaimed
design philosophy to an unprecedented level, and makes a powerful
statement-on-the-art of music reproduction.
