I'm sure you made the right choice to keep the SF. I own the previous Sasha speaker (series 2), which I traded in original Sabrina's for to get a demo pair. While the Sasha DAW is certainly a great speaker, particularly when you get to this level it really is a matter of personal preference.
What I think you might consider is to upgrade your dCS Bartok to the Rossini DAC (and maybe even getting the Rossini Master Clock as well). The Bartok is certainly a great DAC and I was considering it when I upgraded my digital front end a couple months ago. But after doing a side by side comparison of the Bartok and Rossini in my home system, and hearing from a dCS representative on an online forum that there are no current plans to upgrade the Bartok mapping algorithms, the Rossini is a significant step up in sound quality.
Of course another alternative would be to keep the Bartok but add the Rossini Master Clock to it. From what I've read, that still won't quite equal the Rossini in SQ but it will certainly be closer.
