STASIS-R 5.0 Stereo Control Preamplifier

Front View The STASIS-R 5.0 Stereo Control Preamplifier is a classic example of the fine craftsmanship that has been the Threshold hallmark for over 35 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.

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.

Ergonomically, the STASIS-R 5.0 is a pleasure to use. Volume, balance, source selection, mute and programming can be managed with either the front-panel controls or with the hand-held remote. The selected source and the volume level are displayed on an attractive, easy-to-read LCD blue-white screen that switches to display other functions when needed. The rotary digitally-controlled analog volume control allows levels to be adjusted in 0.1 dB increments for precise, repeatable settings.

The 5.0 is an exceptional product in technical terms, designed as a tool to meet the needs of the most demanding audio professional, but it is also, like the well-regarded historic Threshold preamps, one that possesses the magical ability to stir the heart of even the most jaded audiophile.
