MiniDSP MCHStreamer
Have been working with its previous version since 2013 without a single hitch. I integrated the new one in a multitrack interface setup (24ch) and is working flawlessly from day one. Albeit not really cheap, it' s worth its price..Audiophonics service prompt as always.

Very versatile, although not cheap
Veritable Swiss Army Knife for USB connectivity. Although this is not a cheap item, it is very useful. I use it for Toslink SPDIF to USB for my MacBook Pro which it does perfectly, but it can be configured for I2S in/out, Coax in/out, ADAT depending on the loaded firmware. Installing the firmware is easy enough.

Finding a decent Toslink to USB receiver that is better than 16 bit/44.1Khz is quite tricky. There is the Soundblaster X-Fi that can do this, but I was worried about Mac compatibility.

This works perfectly and can be powered by USB or with a 5V header on the board.

The USBStreamer would have sufficed for the rates that I record my vinyl at, but this was only marginally more expensive, and handles higher rates and DSD if I ever want to go that direction in future.
