SAM EO is outstanding but wouldn't suggest it unless I already had a bread & butter type orchestra.
Cinematic in style, great for layering & also my fav for creating & developing ideas.
Again, it depends on what you're going to use for, it sounds great as all SAM products do.
->Also here's a link to try-sound.com, never tried it myself but you may like to check it out to demo SAM OE..
