I have nowhere seen the full components list.
Only the full XELF circuit without any values.
What values are the resistors?

XELF is a very interesting headphone amplifier.

Mine 200 mA per channel....doing very very well as preamp....one of best sounding pleased mids as from lateral expected 😁.

V regulator has to work a lot and shield and ground concept is not finished. ( Unclear for me...but working without any noise and hum...

Close temps are outside 37.7 deg max
+-15 V rails

For me best with opamp LM49720 NA, then opa1652, opa2134 can't separate between the speakers so good as the other's.

Have you read post #2 or #16 ?
Maybe also search "discrete" in this thread ?

Some like to power them with +/-15V LiFePo's.
