Basically I use it for tracking vocals with my FLEA 47. But most of the time the real power of this preamp is to use it as a coloring box: meaning yes it is powerful when used on Spdif from & back to the DAW. Applications : Taming sibillances (see Nashville preamp preset) , add some velvet sweetness to vocals (V76 or Neve VR , sometimes Manley preamp). Add some harmonics or EQ . Finally as a killing weapon all the compressors according to the mix I work on (FET, LA2A etc ..).
Believe it or not : I got several gear here for mastering (STC8, Massive passive etc ) & I sometimes use the Liquid Channel for adding a special flavor on a master.
