I have had both the 1SC's and (now) the 2S's. I absolutely loved the 1SC's in my old, smaller room. Very detailed (but not ruthlessly so) tube-friendly speakers. But I moved to a place with a larger listening room (loft-style layout, a roughly 25 x 25 x 30 quasi-triangle-shaped room), and I kept turning the 1SC's up too much in order to 'fill' the room, and it became clear they weren't 'big enough'. I wanted to retain as much of the 1SC's sound as possible, but in a bigger package, and the 2S was a logical choice. I've had to forego some of the 'ability to disappear' I got with the 1SC's, but have gained more heft, weight and ease in the process, and I still have much of the sonic character of the 1SC (both use the same tweeter, for one thing). It's proven to be an acceptable trade-off for me.
I'm sure the D2's would be even better, but I got a great deal on the 2S's (in Yew wood finish) here locally and am, for the time being, satisfied. If I had a smaller room, I'd probably want my 1SC's back!
