STASIS 7.0 Stereo Power Amplifier

Front View The STASIS 7.0 is a compact version of our more powerful STASIS 8.0, yet it sacrifices nothing when it comes to revelation of nuance and inner detail. While its outer appearance may suggest an obsession with solidity and power, the 7.0 shows its true sonic character in the listening room, where it is a sweet and detailed reproducer of music.

This is not to overlook the 7.0’s capabilities in the areas of bass extension, quickness, and slam; its credentials in these areas are formidable, and immediately apparent. Still, the most noteworthy aspect of the 7.0’s performance is its gentle and honest reproduction of musical subtleties. In this respect, it is arguably the best stereo amplifier of its power rating that Threshold has ever produced.

In fact, 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 7.0 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.

High current capability, the importance of which is often left undiscussed, is something the STASIS 7.0 truly delivers in real-world terms. Able to provide staggering amounts of continuous current, the 7.0 can drive the most demanding 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. 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 truly remarkable. The STASIS 7.0 has raised Threshold’s acclaimed design philosophy to an unprecedented level—and that itself is a statement-on-the-art.
