I know a few producers who record at 44.1 but 48khz is still a very common pro studio standard so as to enable compatibility across multiple pieces of hardware. It's obviously just left over from the DAT connection standard, but most converters use it as a default clock.
For me, it'd mean I'd be able to permanently connect the Kemper to the SPDIF inputs on my card's input channels and skip one step of the conversion process.
THIS WOULD BE AWESOME.
