Octave Audio

Octave is a German manufacturer of tube amplifiers founded by Andreas Hofmann and based in Karlsbad, with a product history reaching back to the HP 500 preamplifier in 1986. The lineup covers preamplifiers, power amplifiers, integrated amplifiers, single ended amplifiers, and phono preamplifiers, topped by the flagship Jubilee line that Hofmann describes as the culmination of his experience and ambitions for the brand. Octave is known for delivering power and stability beyond what is typical of tube designs, earning recent praise from Stereophile for its Jubilee Class A monoblock amplifiers.
