I have been producing for a couple of months now (mainly Deep House). Atm I'm using Sylenth mainly for ambient and pads. These sound good but I would like to go a bit more advanced.

Which VST's (and possible soundbanks) would you guys recommend for these sounds? I am quite impressed by these songs as they are very professional sounding.

Mathew Jonson - Kissing Your Eyes (Tale Of Us Remix) (ambient kicks in at about 1 minute, and progresses 1:30)
