Do standalone digital-to-digital EQ and Room Correction products exist? SPDIF in SPDIF out


Looking at a DAC that has digital S/PDIF (RCA) In/Out called a "monitor loop"..

The idea is to insert your component of choice in the digital path to apply EQ or Room Correction.

I cant seem to find any of these simple digital-to-digital S/PDIF EQs out there.  Many seem to be overkill for this application with their own built-in DACs, multitude of other connections, etc...

Products that almost fit this scenario, but not quite, are:
- Schiit Loki (analog only)
- DSPeaker Anti-Mode 2.0 Dual Core (optical only)

you may want to look at the pro audio side of things. but your most likely going to find similar things that do much.  

I agree that would be a great product. simple room correction DSP in a box. it could be digital in - analogue in with digital out and maybe an analogue out too. 

This would allow the use of room correction with out replacing whole systems that you may already have invested considerably into.
The miniDSP SHD Studio would be my pick. It has Dirac, arguably as good as any DRC system and better than most.
