Pass B1 output cap value

[dubiella]

Hi!

Could someone please give an advice about the necessary value for the output cap in the original B1 buffer in my specific setup?

The original value is 10mF. The input impedance of my power amp is 10kOhm.

How small can I choose the output cap without losing anything in the audible range?
Sorry, I cannot find the correct formula anymore.

Thanks,


Marc

10mF is a bit big.
4.7uF to 22uF would do for an input with 10k input impedance.
If your next stage has a DC blocked input, then you do not need two DC blockers.
Delete/bypass the one of inferior quality.
