rach3master Listening with my AGK-K240 headphones, I like the one with Ozone Imager better. Without it, at least with my equipment and ears, I find a sort of hollow in the mid-range of the piano with the volume being less and the vibancy of the sound diminished compared to what I hear coming from further left and right. It's not quite a "hole", but it sounds further away, or something. There's not quite a gap in the sound stage, but the middle sounds different.
The Imager, as you've used it, fills in that hole yet keeps the sound field expanded fully right and left.I listened carefully, and it's not smearing the sound or making it less clear - just kind of blending it better from the center out to the sides. I don't remember now if there are "wet" and "dry" settings or their equivalents, but you could mess with those too. I find this blended sound to be more what I would hear were I playing the instrument, actually more natural.
Anyhow, I think it sounds better WITH.
Your playing is gorgeous, and the instrument sounds really beautiful too.
Bravo.
