Headphone DAC/AMPs with PC input channels via USB

[edahl]

Where audio interfaces can double as DACs for headphone amps via line outputs, I wonder if any DACs or DAC/AMPs intended for head-fi double as input channels on a connected PC via USB, e.g., such that an optical in on the DAC becomes visible as an input channel on PC, letting you record audio by connecting for example a mic preamp. In other words, like an audio interface but more focused on being a good DAC or DAC/AMP for head-fi than being a passable preamp for recording and monitoring. The closest thing to mind is the RME ADI-2 Pro, but are there any others?
