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. Like its more costly parent, the 3.0 is a classic example of the fine craftsmanship that has been the Threshold hallmark for 30 years. Striking a delicate balance between art and technology, the 3.0 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.

The STASIS-R 5.0 is the culmination of Threshold's years of research and development. 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.


Power Amplifiers
  S/350e reissue - Stereo Power Amplifier
 
  • Classic STASIS design

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.

  STASIS 8.0 - Stereo Power Amplifier
 
  • High-current STASIS output stage, fully complementary circuitry
  • Direct-coupled fully discrete solid state design
  • 200 Watts at 8 Ohms, 400 Watts at 4 Ohms per channel

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.

  S/5000e - Stereo Power Amplifier
 
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.

But power is only part of the S/5000e story. The amplifier employs minimal feedback, attesting to its inherent stability and excellent open-loop performance, and is direct coupled input to output, with no capacitors in the signal path. Like all Threshold amplifiers, it utilizes close-tolerance metal film resistors, and matched JFETs. The result is superb open and airy resolution of low-level detail — the subtle shadings that differentiate musical performances.

The ability of the S/5000e to reproduce transient attack, and to explicate complex musical passages, confirms its heritage — flowing not only from the famous Threshold designs of the past, but from today’s remarkable flagship power amplifier, the STASIS 8.0.

The highly affordable S/5000e brings Threshold’s acclaimed designs within easy reach — it’s state-of-the-art that takes into account the state of your budget.

  S/7000e - MonoBlock Power Amplifier
 
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 ability of the S/7000e to explicate complex soundscapes confirms its heritage--flowing not only from the famous Threshold designs of the past, but from today’s remarkable flagship power amplifier, the STASIS 8.0. Although ideally a single S/7000e will be used for each channel, the most typical 5.1 combination uses three S/7000e amplifiers for Left, Center, & Right with one two-channel S/5000e covering the rear channels. Both amps are equipped with 12Volt triggers so that they may be controlled from the processor. This "intelligent" trigger system also allows them, when used in a multi-channel setup, to turn on and off in stepped sequence.

The S/7000e now makes Threshold the highly affordable state-of-the-art choice for both music and cinema.
