The elysia units I've been using on individual tracks as well as across sub mixes and final stereo outs. All of these elysia units make up an incredibly powerful set of tools and have really helped define and model tracks so they find a place in the mix without losing their heart and presence.
The elysia museq is an absolutely magical EQ. Clear and intuitive controls wrapped around a beautiful sound. The resonant low cut filter and M/S modes allow me to add great levels of detail and spatial expansion. A permanent member of my mix buss.
