加拿大focusaudio/枫叶之声 Liszt Prelude 胆机功放
•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
•class AB 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 M6 grade 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
