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
over 35 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 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.
Ergonomically, the unit is a pleasure to use. Volume, balance, source selection, mute and programming can be controlled with either the simple front-panel
controls or with the supplied hand-held remote control. The source selected and volume level are displayed continuously on an
attractive, easy-to-read LCD blue-white screen that switches to display other functions when needed. This display, together with
the rotary digitally-controlled analog volume control, allows levels to be adjusted in 0.5 dB increments for precise, repeatable
settings.
The Threshold STASIS-R 3.0 is an exceptional product in technical terms, designed as a tool to meet the needs of the
most demanding audio professionals, but it is also one with a truly remarkable ability to stir the heart of even the most jaded
audio purist.
