STASIS 8.0 Stereo Power Amplifier

Front View 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.
