I liked the 3010 S2 very much, although I didn't hear it with B&W speakers.
To me it sounds like a very good price. The cheapest I've seen the S2 (non-D) version, new, is €1,350. I believe the D model is retailing for around €2,000—which is around €200 more than the previous model.
No idea how well the DAC in the new D model performs, though.
