I know outboard USB to spdif converters are all the rage right now, but I am trying to find single box solution for a USB based DAC. I also like 24/192 capabilities. The more compact the better, but that isn't as important. Up to $1000, but would prefer closer to $500.
So what DAC has done USB "right" and doesn't need an external converter to get the most out of the DAC?
