Update RCA on PCB: worth it?

Hi,
I hope this is the right section.

I have a Raspberry Pi 3b+ with this digital board:
AUDIOPHONICS Digipi+ PRO Digital interface WM8804 for Raspberry Pi - Audiophonics

I'm using coaxial output and I'm very satisfied with sound (the DAC is Loxjie D30, amplifier is Advance Acoustic X-i60)

So I'm considering to add a new RCA socket for the PCB above.

Audiophonics itself suggest those:
ELECAUDIO ER-106 Inlet RCA for IC Gold Plated (Pair) - Audiophonics

In your opinion, it is worth it? A socket like this can improve the sound?

Second, it could cost me, 16 euros (I paid the board 22, so a little expensive)

I found an Ebay what I consider a clone:
1 COPPIA D'ORO RCA PIN JACK Donna scheda di circuiti stampati socket AV A/V Connettore Presa | eBay

It should be okay with the digital board?

Many thanks
