Ron Sutherland and the music reproduction components that he has created are legendary.

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.

Inside the battery-powered Ph3D

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.
