I'm looking for an Amplifier to drive my new 32 ohm impedence Philips Fidelio X1 Headphones.
My personal project is illustrated below:
Q3 should be change by 2 diode 1N4148 with related R25 value.
The amplifier factor should be not high, here is 5, there is no overall negative feedback.
Below the Simulation of distortion with V2(Vin)=1Vpk, V(R6)(Vout)=5Vpk F=1kHz
|Second armoni c distortion for: V2(Vin)=1Vpk, V(R6)(Vout)=5Vpk F=1kHz|
|HeadPhones Amplifier Bandwidth|
I hope I'll make it soon...
