I've only read the first post of this thread, let me give you my personal feedback: If you are after realism VSL is what you need without any doubt. You will get all the articulations you want and a brilliant interface to manage them (playing or notating). Let's say you choose a Flute matrix, set the Keyswitches and MIDI CC the way you feel more confortable and play it (of course you need some VI playing technique) it will be the same as listening to a Flute player in your studio.
Yes, the sounds are dry. This means you will be able to place them where you want (close or distant) and to get the feeling of small/medium/big ensembles (and venues) according to the music needs. Of course it means you will need some nice convolution reverbs and of course it will take time and experience to learn how to use them properly (in conjunction with faders and power panners) if you're after a good placement of the sections. This community and the Beat Kaufmann tutorials will help you to master these tecniques.
I purchased SE bundle 1 and Bundle 2 + the Vienna Suite less than 5 months ago. I never used VSL samples before and i swear i am extremely satisfied of the whole package. My advice: if you don't need the Harpsichord, the Pipe Organ and the Chamber Strings right now you can go for the SE Bundle 1, if you just want to check the outstanding quality of VSL and your music could be played with the basic articulations you can choose the SE Volume 1.
