designed by valve supremo, Tim deParavicini, 

the Quad twenty-four P is a stunning addition 

to the range. designed holistically with the 

power and pre-amplifiers, it brings an entirely 

new dimension to vinyl listening 

QC-phono stages

The Quad

For  the  analogue  purist,  the  combination  of  a  good  valve 
amplifier and a good turntable is the closest possible approach 
to the original recording.

There  are  two  options  for  adding  such  functionality  to  our 
valve pre-amplifiers.

A solid-state module is available for the standard QC-twenty-
four pre-amplifier (known as the QC-24 phono stage) which 
allows  direct  connection  of  a  turntable  with  an  internal 
switch to change between moving coil and moving magnet 
cartridges. This can be fitted as standard or added later.

For the connoisseur however, there is the Quad twenty-
four  P  dedicated  valve  phono  stage.  This  has  been 
designed  for  Quad  by  valve  supremo Tim  deParavicini 
-  probably  the  finest  valve  amplifier  designer  in  the 
world today. It has been voiced by the finest ears in the 
industry and will add an entirely new dimension to your 
enjoyment of vinyl recordings.

This unit features a moving magnet/ moving coil toggle 
switch on the rear, and a choice of direct full level output, 
or a variable level output if you wish to connect directly 
to a power amplifier.
