I use an RME ADI-2 Pro for vinyl ADC.
In my system, the RME outputs DSD256 via USB to a DIY HQPlayer Server that performs digital riaa.
I get the sense that there are not too many folks taking this approach.
HQP has custom built-in drivers for the RME devices, so they configure together easily.
RME ADC will also benefit from upgrading the external 12v power supply.
