Under 800-1.000 $......there's only one for me: RME HDSPe AiO (Hammerfall). A very nice card. All analog and digital in and outs are working simultanously. Very fast performance and good sounding converters. You have the possibility to enhance that card later with seperate A/D and D/A if you want. Great for VST instruments and connecting analog or digital hardware processors from your studio into your DAW.
