I picked up the Mutec MC3+USB, it works really well. It can take USB and output via consumer SPDIF, ,BNC, AES/ EBU, and Toslink simultaneously. It can also take those inputs and output via USB. It reclocks internally and can also reclock externally with a 10m reference clock.
Not cheap but at $1300 but I think it makes a noticeable difference with any digital source. I am using it with the LHY Audio OCK -2 10m clock I can't speak to the Denafrips but the LHY is made in the same OEM factory for Jays Audio. I was really surprised by the quality of the LHY stuff.
