DIY - OSMC over RP3B+

[Beans78]

Dear DIY peers,
I have a DIY setup back home in living room made assembling Class D 2.1 setup. It works seamless and been around since 3+ yrs.

Intend to upgrade this on a Suptronics X6000 DAC with RP for computing. Anyone here with alike DSP DAC combination pls let know. Need to get some guidance.

Thanks in advance folks
