"Performance Realized": Sutherland Dos Locos Transimpedance Monoblock MC Phono Preamplifier Delivers You-Need-to-Hear-It-to-Believe-It Purity and Clarity

Born from the innovative spirit of the Phono Loco, with its pioneering all-transimpedance approach, the DOS LOCOS stands as a significant advancement in Ron Sutherland's artistry. For the first time, he teamed with trusted, passionate experts to add an ear-approved essence to his already proven approach to elegant circuitry.

Sutherland and team patiently experimented with combinations of parts and processes until they happily arrived at the moment where the music left everyone speechless. Only then did the DOS LOCOS arrive.
Everything that made the PHONO LOCO such a landmark piece — its no-compromises approach with no concession or allowance for anything that clutters the signal path — is refined to the point of pure musicality with the dual-mono DOS LOCOS.

This phono preamp is about a group of like-minded music lovers relentlessly pursuing a sound that, before now, only existed in their imaginations. There is no explaining the DOS LOCOS — not in the technobabble way normally used to sell audio components. By their own admission, Team Sutherland "moved into" something that goes well beyond technical description. Their journey didn't center around a test bench but rather the sweet spot of their listening room. The decision tree throughout the entire project revolved around one simple question: Performance realized?

Sutherland's approach to audio engineering is disciplined and values-driven, focusing on high-quality, reliable components without succumbing to the temptation of adding unnecessary complexity. The minimalist design ensures a signal path of unparalleled purity, letting nothing stand between you and the music. The brilliance of this design isn't in how many parts are added to the signal path but rather how few. But those things have always been hallmarks of Sutherland Engineering. The DOS LOCOS is at a new level. It adds an indescribable mysticism that simply must be heard to understand.

Be warned. Even if you fully grasp how significantly a phono preamp affects the sound of your vinyl playback, you're not prepared for this. Integrating the DOS LOCOS into your system isn't just enhancing your setup; it's revolutionizing it. Beta listeners have reported a transformative experience, with the DOS LOCOS revealing fine details and clarity in recordings that were previously obscured, all with effortless power and not a hint of harshness.

This is your invitation to listen — to truly listen — and to be moved.
