quad image
Razorwit You probably should check out the IK Quad Image as well. It's multi-band stereo enhancement with M/S capabilities. I own (and like) both it and Ozone and they are both very similar, but you can get the Quad Image as a stand-alone for a fairly reasonable price. Dean
bitflipper Channel Tools is good too but nowhere near as comprehensive as iZotope Ozone 5's stereo imaging tool! Apples 'n oranges. Actually, Channel Tools offers quite a bit more functionality than either Waves S1 or Ozone's stereo tool. What distinguishes Ozone's is the ability to define multiple bands and apply different amounts of M/S balancing and delays to each band. I don't know of any alternative plugin that lets you do that.
