If conversation lulls, some key words or phrases are bound to revive "spirited" conversation; politics, sports, the environment and if you're among audio enthusiasts, just say "vacuum tubes". Within moments you'll be hearing about texture, tonality, speed, dynamics, bass control and other audio arcana. It's usually an either or battle between solid-state and tubes. It needn't be that way.Since 1975, Andreas Hofmann has been developing technologies that, by 1980 as Octave Audio, has harmoniously brought together the seemingly warring camps. He has created some modular designs that allow the end user to "customize" the features and sound to maximize system performance. Judicious use of solid-state circuits in support of the full-range tonal and dynamic precision of tubes has brought German engineering in support of sonic excellence to audio enthusiasts everywhere.
