Inspire LP-3a

About the Inspire LP-3a

The Dennis Had Inspire LP-3a is a high-end all-tube preamplifier that uses three 6SN7 tubes (often New Old Stock GE tubes recommended by Dennis Had) and a 5Y3 Sylvania tube rectifier. It is designed as a line stage preamp with no phono section, offering 3 inputs and 2 outputs. The LP-3a is known for its fully regulated power supply and robust build quality, including hand-wired construction and epoxy-secured components to ensure reliability and reduce microphonics. It is capable of delivering up to 30 volts output and is praised for its clear and detailed sound, although some users note it may not dramatically improve imaging or soundstage compared to other tube preamps. The unit is relatively rare and can be found used, sometimes requiring minor repairs or tube replacements due to its age and tube-based design. The LP-3a is part of Dennis Had's Inspire series, which continues his legacy of designing high-quality tube audio equipment.
