QUAD Vacuum Tuber Amplifier Systems  II-FORTY Brochure & Specs Download Page 2

ThE  QUAd  II-FoRTY  valve  amplifier  is  not  only 
one  of  the  finest  sounding  valve  power  amplifiers 
available in the market place today, it is an aesthetic 
and engineering masterpiece.

An  understated  elegance  lies  beneath  the  smooth 
curves and lustrous finish, for the power amplifiers 
use a circuit dating back over fifty years to the time 
when vacuum tubes ruled the electronics industry 
and  Peter  Walker  considered  by  many  to  be  the 
master of audiophile design. 

he  often  shunned  traditional  thinking,  preferring 
to go his own way, relying on excellence in circuit 
design.  Circuits  that  are  still  admired  today  by 
the  finest  minds  in  electronics-for  their  stunning 
performance and, by today’s standards, simplicity.
