All CFP Non Global Feedback Amplifier
Hi, I take some concept from Pioneer A09 Amplifier and result this, what do you think?
The basic idea is: CFP buffer + CFP Voltage amplifier + CFP Buffer + CFP Current amplifier + DC servo. The amplifier can use in headphone amplifier or low power amplifier. Around 30 inexpensive transistor, but, the amplifier can by simplified to 16 transistor, without CFP and a simple current source. THD = 0.016% @1kHz, 4Vpp, Rload = 8ohm
