I have a Raspberry Pi 3b+ with a Kuman SC07 digi card. The card is a sort of HiFiBerry DAC+ clone, equipped with a Wolfson WM8804G chip.
My Raspberry (with Volumio 3) is wired with a coaxial cable to my amplifier Marantz Pm6005.
I configured the Kuman card in Volumio 3 as I2S DAC/HiFi Berry Digi and it’s correctly recognized and working as expected.
Using a coaxial cable I get the Marantz DAC to work, so I’ve never worried about the quality of the digital sound card mounted on the rp since I am very happy with how my system sounds.
But now, I wonder, is this a correct assumption? Could I expect an improvement in sound quality using a good quality digital sound card such as the Allo Digione?
And if so, how relevant could the improvement be in your opinion?
Thank you in advance!
