Bel  Canto  grew  from  the  quest  to  achieve  the  ultimate  musical

satisfaction  from an  audio  system.  This goal  began  with  the  discovery  of  the
inherent sonic qualities and  musical  performance  potential  of  a  nearly  forgotten
technology, the single-ended triode amplifier.  The ability of this type of amplifier
to recreate the musical experience and evoke a  powerful  emotional  response  in
the listener, much like the live event, inspired the development of the SET line of
amplifiers through the ultimate expression of this technology.  The SET 40 circuit
was developed to be used as both a cornerstone for a modern audio system and
as  a  reference  tool  to  explore  the  reasons  behind  the  single-ended  triode
amplifier's uniquely musical attributes.

For the better  part of  a  decade  this quest  continued  and  has

resulted  in  a  line  of  fine audio  amplifiers  that are  designed  to  incorporate  the
unparalleled  musical  reproduction  of  the  single-ended  triode  architecture.  Bel
Canto Design's goal for the SET Line is simply to provide the most expressive and
powerful musical experience outside of the live event.  Bring some of the greatest
musicians and their performances into the intimacy of your home, for many years
to come.

The SET  40  represents  the  attainment  of  a  goal and  is  designed  to

provide very high value and to retain this value  for  many years,  both because  of
the  quality  of  design  and  manufacturing  and  also  the  timelessness  of  each
component's musical performance.
