I think it's odd what people are making out of this. Almost a quasi-religious discussion. Even more so considering the fact that the Synchron series so far has been still very much in line with VSLs "philosophy". Some people act as if the Synchron Strings were swimming in a sea of reverb and had this totally distinct, immutable sound, like it came straight out of a Hollywood movie.
Quite the opposite is true. SyS might be the driest "wet" library out there. It's not at all comparable to the Spitfire stuff or whatever. It has 100% VSL character - pristine, flexible, more "classical" - and has such a subtle reverb tail that would hardly get in the way of anything you might want to do. And the multi-mic setup is exactly what you need for the same flexibility you always had with VSL. If you need a closer, drier sound - what's the problem? Dial in the mics accordingly! It's easier and faster done than previously.
The most notable change is that due to the realistic spatial depth, the samples simply sound more natural and "real" than the older libraries.
It seems to me that some of the notions expressed here have more to do with tribal instincts and "choosing sides" than with using one's ears.
