I'm a big fan of this plugin. The sound is not trying to emulate any real-world space, so you are not going to find any sort of 'room' or 'hall' settings really. It has a unique sound that, to my ears is gorgeous. However, it IS a bit of a processor hog, so it's best to use the lower quality settings while working and save the highest quality for final bounces. The preset management system is a bit wonky, but if you tend to save presets with your DAW, then it won't make much of a difference. The processor use and preset systems are the reasons I gave it a 9 instead of a 10. The sound is a 10 to me.
