  Awards & Reviews
   
     
 
  • 24 step fully remote discrete volume control for great convenience.  Volume control uses the shunt method with only a single Tantalum resistor on signal path to retain best natural sound

 
 
  • can be configured as a volume control integrated amplifier or as a direct input power amplifier.  Both can accept RCA & XLR inputs

 
 
  • Push-pull circuit with deep class A bias to get the sonic benefits of class A operation and yet maintain a fairly good power output efficiency

 
 
  • special auto bias circuitry without the need for frequent bias adjustment

 
 
  • driver stage through excellent low distortion cathode coupled phase-splitter circuit

 
 
  • custom designed wideband output transformer for Prelude, with the use of double C core transformer for the Sonata

 
 
  • German made Mundorf silver oil coupling capacitor for Prelude, ultimate performance silver gold oil for Sonata

 
 
  • extra high current power supply transformer with high grade grain oriented silicon steel laminate. Ultra fast rectifier coupling to Mundorf film capacitor and 4-pole electrolytic capacitor to enhancing extension for both low and high frequencies
