Little Dot I+ output coupling size when modding for preamp?

[Mahidi]

Hi I wanna mod my LD I+ with 3.5mm female socket for preamp use with toggle switch.

But im wondering if I need to change the Coupling Cap Value to get good enough bass when feeding it to my power amp?

It all depends of the input impedance value of your power amp.
