The Man
Gryphon Audio Designs is the
brainchild of Flemming E.
Rasmussen and the fulfillment of
a lifelong dream to allow the
purest essence of the live music
experience to be recreated in the
home environment.
Rasmussen holds a degree in
painting and graphic arts from
the Aarhus Art Academy,
Denmark. During his studies,
Rasmussen developed close
relationships with the local music
community and designed many
LP covers and concert posters.
After graduation, he taught photography and painting and
designed textiles, before founding 2R Marketing, which quickly
became Denmark’s leading High
End audio import company.
Gryphon Audio Designs was
founded in 1985 as an offshoot
of 2R Marketing, The first product, the now legendary Gryphon
Head Amp, grew from a one-off
spare time project developed
only for the designers’ own home
systems. Although the Gryphon
project was initially strictly a
hobby, not an actively pursued
commercial venture, demand
generated by reviews and wordof-mouth led to the formal establishment of Gryphon Audio
Designs as a separate corporate
entity.

The Gryphon Master
Tape Collection
In the Gryphon listening rooms,
we are fortunate to possess a
unique library of more than
1,000 original master tapes of
recordings made during the
Golden Age of studio engineering from 1956-1976.
Unlike conventional commercial
releases, our master tapes capture the dynamic contrasts and
subtle inner harmonic structure
of the musical event, forcing us
to work to a higher standard in
our efforts to maintain the integrity of the original musical performance.
