INTRODUCTION 

 
 

Congratulations and thank you for choosing OCTAVE 

 

  
 
 
 

V 110 SE 

 
 

You are now the owner of one of the world's most innovative and reliable amplifiers. Look 
after it, and it will provide you many years of listening pleasure. 
 
You often hear people claim that tube amplifier design has not progressed for years. The 
operating  principles  of  tubes  have  indeed  been  documented  extensively  and  are  well 
known to amplifier designers. Of course, the same can be said for transistor amplifiers. 
 
However, advances in both technologies are still possible thanks to the development of 
innovative  and  improved  components,  our  greater  appreciation  of  the  fundamental 
principles  and,  of  course,  deeper  and  more  advanced  insights  into  the  interaction  of 
amplifier  and  loudspeaker.  With  tube  amplifiers  in  particular,  a  general  reluctance  to 
depart from the classic circuit designs has not done the technology any favors. Although 
today's loudspeakers and source equipment provide better performance than ever before, 
they also present greater demands on amplifiers. Modern sound reproduction equipment 
delivers a level of performance at a price that simply would not have been possible 20 or 
even 10 years ago. 
 
These advances have been achieved through the application of the latest technological 
developments as they become available and affordable. OCTAVE has specialized in tube 
amplification  for  the  past  30  years,  during  which  time  we  have  developed  a  number  of 
innovative  technologies  that  have  earned  us  a  reputation  as  one  of  the  leaders  in  the 
field. 
 
 
Here's wishing you many happy hours of musical pleasure!
