The STASIS 8.0 & 7.0 amplifiers

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.  

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.

The S5000e & S/7000e amplifiers

The S/7000e combines one of Threshold's most well-regarded traditional values--prodigious power at an affordable price--with the features required for Home Theater.

The S/7000e is the heir to Threshold’s legacy of high-current designs that effortlessly command and control demanding loudspeaker loads. But power is only part of the story. As one would expect from its audiophile pedigree, the S/7000e employs minimal feedback and is direct coupled input to output. The result is superb resolution of both musical scores and cinematic sonic effects.

The S/5000e represents a return to one of Threshold’s most well-regarded traditional values: prodigious power at an affordable price.

The S/5000e is the heir to Threshold’s legacy of high-current designs that effortlessly command and control demanding loudspeaker loads, delivering the power needed for full revelation of dynamic contrasts and bass extension.

The STASIS-R 3.0 & 5.0 stereo control preamplifiers

The STASIS-R Series technology is the culmination of Threshold's years of research and development -- and is arguably a benchmark against which other preamplifiers, regardless of price or technology, must now be compared.

The STASIS-R 5.0 Stereo Control Preamplifier is a classic example of the fine craftsmanship that has been the Threshold hallmark for 30 years. But it's also Threshold's latest and most eloquent statement-on-the-art of preamplifier design. Striking a delicate balance between art and technology, the 5.0 is a stunning performer both in the lab, where it displays unsurpassed precision, and in the listening room, where it shows off its unparalleled transparency, detail, and depth of image.  A truly balanced, fully remote controlled preamplifier, with gain stages based on the highly acclaimed T2, the 5.0 is arguably a benchmark against which other preamplifiers, regardless of price or technology, must now be compared.

The STASIS-R 3.0 Stereo Control Preamplifier is Threshold's latest application of the technology first employed in Threshold's flagship design, the STASIS-R 5.0.
