With $4000 you can get some pretty decent stuff I say!
Platinum is around $1300 if I remember correctly. This gives you 130 GB, more or less of quality sounds. It has the 3 mics, etc, so it's ok. BTW, PLAY versions seem to be somewhat unstable as of yet, so maybe wait a while? After all EW are known to be throwing offers every second week, so you could only get a 20% off or something.
The problem with EW is that it cannot really handle successfully 'smaller' and more sensetive sound. At least me and my Gold bundle have been rather unable. It's not impossible, but it's not been designed this way!
Until now, the problem with EW products was the lack of legato and portamento. This appears to have been corrected, but again, not sure how it actually sounds in PLAY.
So with the rest of the money you could compliment yourself VERY VERY well!
for example, for TOP jazz stuff you could go for SONIVOX, but it does cost above $2000. It does seem to be the only library able to do amazing jazz stuff, production wise. And it does appear that the player, which is based on halion I believe, STILL has issues.
Then it's the other stuff that you could compliment yourself with. Solo strings: Dan Dean. They are rather good and intimate, so a piano quintet could work well. The Garritan solo strings have been discontinued, otherwise I would recommend them wholeheartely. The WIVI stuff (google it), are synthesised but VERY realistic and he has brass and woods. Woods come also by westgate, which are very good and excellent for solo stuff.
The idea would be to get a full orchestra as your main pallet and various smaller stuff to surround it. Some things to think about.
Generally working depends on your DAW as well. If you get something with 8 or 16 GB then you won't have to bounce (yet and until the new products come to earth), so you should be fine. A good soundcard and good monitors to really listen to your well spent $4000 would also be recomendable.
That's all ffom me on a very hasty post and sorry for any tpyos!
