Headphone amp based on LineUp's Navaho amplifier

Yes, I think you are right. It was the wrapping.

I'm still in simulations I think Toshiba/Onsemi combo tansistors are a good choice
Distortions at 1 kHz sine are too easy so..

First attempt

THD at 20kHz is very low.
And FFT looks promising.
Good work!

Hi all

I think it will look like this

Two amplifier PCBs and two power supply PBCs. Channel grounds connect only at the socket

Power supply grounds connect only at the amplifier PCB
Power supply prepared for transformer on PCB (this power supply is already built / tested)

Great PCB as always 🙂
So there will be sort of a star ground. No groundloops.
