Description 

 
Congratulations,  you  have  just  purchased  one  of  the  highest  performance-per-dollar 
audiophile  products  available!  The  Bugle3  was  designed  to  be  a  simple  yet  flexible 
phonostage  capable  of  achieving  very  good  sound  quality,  comparable  to  far  more 
costly  units.  It  is  a  third-generation  circuit  topology  using  low  noise  audio  opamps 
implementing  passive  split-equalization  filters,  and  a  low  output  impedance.  Loading 
and gain are adjustable via DIP switches.  
 
Available  as  a  PCB-only  kit!  You  must  purchase  all  other  components  to  complete 
assembly.
