It uses very little CPU which makes it easily usable on all channels.
I could effecuter a comparison with the Sonnox and GCO Kjearhus.
It is clearly over. The GCO seems completely kill the momentum while the Sonalksis limit but not kill, it's crazy, all shades are satisfied. Deplus, the definition and nature of the signal are satisfied. Treble and bass are preserved. It's simple we do not distinguish between input and output, except that the momentum is reduced. GCO is lost with the bass and also the definition. With Sonnox, the definition is preserved, but you lose the bass. We can always use the Warmth for pick up but it's good to try to restore what was lost and I'm not sure of the results on all sources. Sonalksis with the sound record is simply beautiful, no sound metric, claps immediately and without having to fiddle with 50 params. You can do anything with, as well as smooth add a dynamic random violent attack on a signal a bit dull (kick etc. ...). Until now, the best compressor I've seen.
The price is quite expensive, but it is similar to other quality plugs.
For those who have the budget, go for it.
