I've used perfect because I liked the sound of the KPA and thought that was 100% authentic. Now why are we admit that wasn't so authentic and now is more? And it's now more authentic or it's more authentic without the pure cabinet and we just think that now it's more authentic because the sound it's more liked with it pure cabinet to our ears?
please read the document:
without Pure Cabinet you get the authentic mic'ed cab tone
with Pure Cabinet you can go from that mic'ed cab tone towards an "in-the-room" tone.
"As a proof of concept we have let a number of these "desensitized" professional players and producers test the new Pure Cabinet feature in several situations. Their first reaction was along the lines of: "That pain that I got used to over the years, is now gone. It's a huge relief." They did not want to deactivate Pure Cabinet in any situation - there was simply no reason to switch it off again. So, much to our surprise, they did not miss the original mic'ed sound for a second. Not one of them looked back."
