Generally speaking, a DAW does not introduce noise.

Your interface does. So you may want to edit the question Johnny.

Signal to noise starts at the preamp. I'd consider getting a couple good preamps in whatever configuration you prefer.

For an interface many here use Focusrite (I have one, though I also have 3 Delta 1010s available and tend to beat on those more, but they are getting long in the tooth). Focusrite preamps are nice. 90db (member here) posted a nice deal in another tread.

Your old SD had a synth on it also, didn't it? Or am I confusing models. If it did, are you comfortable splitting up audio and MIDI, or do you still want it all in one?
