The Importance Of Wires 

Interconnect  and  speaker  wires  are  an  important  element  in  your 
stereo  system.  Interconnects  are  available  which  will  permit  a 
reference  quality  system  to  blossom  and  fulfill  its  promise  of 
musical reality. Others will strangle the system to the point where it 
becomes  little  better  than  average.  To  complicate  matters,  our 
experience  suggests  that  the  choice  of  interconnects  will  be 
system dependent - those that are top ranked on one system may 
be  a  poor  choice  for  a  different  system.  Consult  your  conrad-
johnson dealer for recommendations for your specific system. 

Performance Tip 

Warm  up  the  ART 

108

A  Amplifier  before  listening:  The

sonic performance  of the ART 

108

A Amplifier improves noticeably

as  the  unit  warms  up.  The  midrange  becomes  more  lucid, 
the  highs smoother,  and  the  soundstage  expands.  The  warm  up 
period  can be expected to last about fifteen minutes.
