I'm demoing Reference 3 for speakers at the moment.
It's great that it has such a usable and easy to understand process, but don't forget the more technical advanced users. I really would like to read a bit more about the technical side.
When I'm researching other correction products, I mostly get a pretty clear description what it does on a technical level. I really would know a bit more which speaker/room issues are exactly addressed. At the moment it's kind of a blackbox for me.
1) Even with the listening spot correction off (so the speaker balance should be the same as when disabled, i guess), I think that the stereo image may get a tiny bit wider with Reference 3 turned on. It's sound good, but I need to understand if this is correct or a side effect.
2) Is it only correcting the frequency response and volume (for stereo), or is it also correcting the impulse response or phase response from a speaker setup or anything else? (* I don't meant a correction from phase problems just intruduced by the correction filter, but more the (speaker) response in general).
3) Is this the same for all filter modes?
