Voxengo GlissEQ
I use Voxengo products every day and am still blown away by the quality of the EQ/filtering effects. GlissEQ and Redunoise are simply unique and can work wonders with poor source material.
The most recent purchase has been the Analogflux Suite. This really can impart a beautiful feel to a track. TapeBus is the best tape emulation I've heard yet.
You could pay thousands to get a plugin pack which isn't as good as Aleksey's plugs - they've certainly helped my studio out financially!
If you're not sure about buying a Voxengo product then download the demo and spend some time using it on your own mixes. I can't imagine how anyone could fail to be impressed.
Dave Rich - LividstudiosIt's pretty simple why Voxengo plugins are so good - Alexsey has a better ear compared to other developers.
His plugins sound so 'musical'. I've used many other plugins that technically perform their designed function, yet somehow just don't sound good.
I now have a whole set of expensive plugins that are just taking up drive space. They simply don't sound as good as thier Voxengo counterparts.
