I have been using the Compulator. It is a very nice compressor. As a result of always looking for " something better" , I ordered the FX Engineering RAF Mirage. It came today. I do not have the patience to put it through a Bongomania in-depth test but I did A/B them both quite a few times. The compulator won clearly. However, this is not to say that the mirage is not good. Perhaps some would say very good. Very clean. And as they say in the booklet: " you will not hear the compression mechanism reacting to attack, or pumping to increase sustain ". This is true. I wish the Compulator was like this. To my ears, the Demeter is fatter and deeper. I also heard some minor almost " distortion like " noise artifacts when the Mirage compression was turned up. So back it goes. I am only out shipping costs both ways. I may try the Frantone Sandwich. If that goes back also, I will stick with the Demeter and rack mount.
