INTRODUCTION, FEATURES AND TECHNOLOGY

Thank  you  for  purchasing  the 

Brio-

R

the  latest  version  of  Rega’s  best

selling amplifier. 

Housed  in  a  brand  new  case  the 

Brio-

R

draws  on  the  pedigree  of  the

previous  three  incarnations  of  this  model.  The  sonic  recipe  for  the  Brio

embodies  the  best  in  traditional  audio  circuits  with  excellent  engineering

practice. 

A newly designed output amplifier in the 

Brio-

R

was born after extensive

research by our engineers to develop a low source impedance emitter follower

Class  A  driver  stage.  This  is  based  around  a  complementary  pair  of  150w

Sanken  Darlington  output  transistors.  The  technical  and  sonic  improvement

gained  by  the  use  of  low  impedance  drivers  is  well  known,  however  it  can

feature  high  standing  currents  in  the  driver  stage  when  using  standard

transistor  configurations.  By  combining  the  low  impedance  driver  with  the

Sanken  Darlington  transistors  (with  their  imbedded  thermal  bias  network

running at a lower standing current)  this combination forms a complementary

emitter follower emulating Class A conditions with good thermal stability with

lower standing currents in the driver stage.
