Guy, obviously you have a certain expectation about _how_ a string section is supposed to sound - which is a good thing. All I can say is that there are so many examples about sweet-sounding, slow movements in our demo-library that it is hard to believe that I could point out another one that offers you a completely different point of view.
But anway: My favorite pieces would be all the slow tracks by Kuno Schmid, especially "Meditation", and the excerpt of Mahler's "Adagietto" from the 5th symphony.

But in the end, it is quite possible that you are heading for a much more processed, muffled sound, which isn't covered by these examples.
