I use a Focusrite Saffire 26 Pro I/O, which is a firewire interface. It will do up to 24/196, but I have been running it at 24/96 and using it as my Moving Coil Phono Preamp with Pure Vinyl, I'll be using it to archive LP's as well when I get some time.
On several of my systems, I also use a cheap "Instant Music Now" 16/44.1 USB powered DAC/ADC from ADS Tech, that is great for the price.
