Sutherland Insight phono preamplifier

The Sutherland Insight can be viewed—and appreciated—from many angles.

Ron Sutherland’s favorite is “pride of ownership.” Although not expensive by high-end standards, the Insight is a combination of solid, thoughtful engineering – with an artisanal attention to every design decision. Every detail matters; good enough is NOT good enough. All the areas of performance, aesthetics, reliability, circuit design, circuit board layout, parts selection, packaging — ALL of those aspects must seamlessly dovetail into one expression. For those with a taste for understated elegance, the Insight will deliver an
enduring pride of ownership.

The physical artistry is a means to solid, reliable, musicality. There is no affectation. Just a simple, pure link to your recorded treasures. It faithfully delivers musical joy, year after year.

Conventional designs use inexpensive, low-quality computer rocker switches. Their design is inadequate for calibrating the low-level signal from a phono cartridge. To offer the user a wide range of options, while maintaining signal integrity, the Insight uses gold-plated header pins and gold-plated shunts. They offer high-pressure and large surface area contacts.

Each channel has two configuration headers: One to select cartridge loading and an-other to select gain.

Sutherland Insight GAIN ADJUSTMENTS

Each channel has two configuration headers: One to select cartridge loading and an-other to select gain. When changing configuration, be sure to set each channel to the same value. Options are printed directly on the circuit board next to the configuration headers.

There are five available gain settings.

• 40 dB
• 45 dB
• 50 dB
• 55 dB
• 60 dB

Gain is set using the supplied, gold-plated shunts. There is a gain setting header block for each channel. Position the shunt to the desired gain value. Be sure to set the gain of each channel to the same value.

Sutherland Insight Optional Internal Upgrade

The INSIGHT can also be ordered with an optional internal Linear Power Supply board. This LPS circuit board has a toroidal power transformer followed by rectification and extensive low-pass filtering. A cascade of passive R-C filtering provides extensive and effective isolation of the audio circuit from any noise or disturbance on the incoming AC power line. The LPS circuit board is a popular option that adds a more refined musicality with a more solid foundation for dynamic expression
