Audio Research products are all made by hand in our Plymouth, Minnesota facility.   Connections are hand-soldered, not press-fit nor wave-soldered.  All metalwork, boards, transformers and major parts are American-made and sourced locally.  We take a great deal of pride in our workmanship, and so will you.  You'll certainly hear the difference.
