Ron Sutherland's Companion Dolcé.

A Missouri farm boy with a keen talent for physics and electronics, Ron Sutherland first captured the attention of the high performance audio crowd as the ‘Logan’ half of the storied Martin-Logan loudspeaker company.

In recent years Mr. Sutherland has evolved his current business, Sutherland Engineering, Inc., into a vehicle for the improvement of music reproduction through his continuing advancement in phono preamplifier design and technology. Today Sutherland phono preamplifiers are regarded as some of the best and most truthful ever available at any price.

A look inside the Argentum

Ron Sutherland’s designs feature true dual-mono circuits and totally isolated power supplies for superiorly quiet audio signals. He pioneered the use of batteries to power phono preamplifiers and now Mr. Sutherland has pioneered the use of isolated, dual-mono electrical power supplies in a phono preamplifier. Sutherland products are thoughtfully conceived and constructed, and they reproduce music with a palpability that is rarely matched by any audio component.

The 20/20 features dual-mono electrical power supplies.

We invite you to give these fine products a try. We believe that you will see the value in the attention to detail in the design, the execution of the construction, and the quality of the musical reproduction.

Osage Audio Products is proud to have been appointed a retailer of Sutherland Engineering products. If you have any questions about Sutherland or how these products can improve your listening experience, please call us at 573-696-3551 or email us.

The Sutherland Insight features an ultra-low noise floor and tremendous dynamic capabilities.

Click here for a PDF download of the Insight owner’s manual.

The new Insight phono preamplifier from Sutherland Engineering is the new reference in performance for reasonably-price phono preamplifiers.  Adjustable for both moving magnet and moving coil phono cartridges, the Insight offers complete electrostatic and magnetic interference shielding, gold-plated headers and shunts, separate and completely isolated power supply and audio sections, and cold-roll steel chassis and casework construction with a baked-on epoxy finish.

Also included is a true dual-mono circuit layout, as well as Wima polypropylene/film capacitors and Dale-Vishay metal film resistors in the audio section.  Both the configuration setting contacts and the RCA jacks are gold-plated.  An IEC socket is installed for the use of any IEC power cord.

The TZ Direct combines a trans-impedance input with a proven traditional Sutherland gain stage.

Click here for a PDF download of the TZ Direct owner’s manual.

The TZ Direct features the zero impedance input of the little LOCO combined with a fully-discrete “traditional” second gain stage.  It is a true dual mono design with an integrated linear power supply in each chassis. 

The TZ Direct has single-ended RCA inputs and is designed for use with low output moving coil phono cartridges. 

Specifications:

     Operating Voltage Requirements – 105 to 125 VAC, 10 watts

     Dimensions – 17” wide x 2” high x 13” deep, 15 lbs. net weight each chassis

Retail Price:  $8500.00

The Sutherland little LOCO borrows from the technology of the PHONO LOCO to offer the benefits of trans-impedance phono preamplifier design at a lower price.

Click here for a PDF download of the little LOCO owner’s manual.

Sutherland’s little LOCO is a trans-impedance design that works by amplifying the current output of the phono cartridge.  The little LOCO is available in both a stereo and a mono configuration.

The little LOCO is designed to work optimally with phono cartridges that have a very low internal impedance.  Use of this phono preamp requires that your tonearm cable have a shield that is connected to a separate ground wire that connects to the ground lug of the little LOCO and that does not connect to the RCA plug shell, and that a floating connection to both phono cartridge coil terminals exists. Please be sure that your tonearm cable meets this requirement.

Please consult with us about your particular situation to ensure that the little LOCO is the right choice for your system.

Specifications:

     Operating Voltage Requirements – 105 to 120 VAC, 12 watts

     Dimensions – 17” wide x 2” high x 13” deep, 15 lbs. net weight

The Sutherland TZ Vibe trans-impedance phono preamplifier breaks new ground.

Click here for a PDF download of the TZ Vibe owner’s manual.

Trans-impedance phono preamplifiers have been expensive and have required balanced tonearm cables, up until now.  The Sutherland TZ Vibe uses the basic audio circuitry of the KC Vibe along with the trans-impedance circuitry of the little LOCO to make a cost effective and user friendly phono preamplifier that also offers the benefits of trans-impedance design.

The TZ Vibe has RCA inputs and will work with any known phono cable.  No longer is a balanced phono cable necessary.  The TZ Vibe will also work well with moving coil phono cartridges that have a higher internal impedance than previous phono preamplifiers of this type. 

Specifications:

     Operating Voltage Requirements – 86 to 250 VAC, 5 watts

     Dimensions – 12.5” wide x 6.5” high x 14.5” deep, 6 lbs. net weight
