Octave Audio manufactures all of its products in-house, with parts sourced mostly from local vendors in Germany. The only major parts not sourced from Germany are the tubes, which come from Russia.

Circuit boards are made for Octave Audio by a local vendor; however, even though the vendor has worked for Octave Audio for years, each board is still carefully inspected when it arrives. Martin, who has been with the company 14 years, is shown inspecting the boards made for the company's new HP 700 preamplifier, which will debut this month in Munich at High End 2014.
