If you already have a good quality DAC (or CDP with DAC inputs) but either
a. the DAC didn't have a USB input or
b. the USB input was an older (synchronous) system or only ran up to 48kHz or 96kHz
a good USB-SPDIF interface will allow you to continue using your favorite DAC but upgrade the USB connectivity
Not all USB-SPDIF interfaces sound the same though.
The good ones I have heard are the Wavelink HS and the Offramp 4 (now in v5). My friend likes the Bel Canto REFLink a lot too. The Berkeley Alpha USB is also highly rated. I have not heard the last two so can't proffer any real recommendations.
