Handcrafted in the USA
Unlike the cost driven electronics industry, we cherry pick our parts and assemble the amplifiers by hand in the United States. We use premium components and even hand match the Class A JFETs found in our amplifers. Designing/building headphone amplifiers is our passion and the Spirit AMP is a culmination of months of tweaking and listening. We are confident you will be enthralled by its sonic signature. Advanced audio enthusiasts may also swap out the input opamp and discrete JFETs (not covered under warranty). Specifications of the swapable components may be found in the user guide.
