@Holmz I do think you get the wrong impression of what it is I do or have. I absorb early reflections, as seen from my listening position. That means i stole a lot of energy from the room. I simply don't have the space to redirect it, which would have been a better choice. So I'm using ambient speakers, placed behind the listening position and aimed outwards (away from the LP) to reflect off of nearby objects. It is those speakers that receive a decorrelated mix. The direct sound is not altered in any way, shape or form (*). That original sound still gets send to the main speakers. The ambient speakers give clues of a fake, but better room to the listener, mostly arriving from lateral angles. These cues come in after about 17 to 20 ms after the direct sound, much like a Haas kicker was used or a live end/dead end room.
I'm not saying anyone should want to do anything I do. I just prefer this route, as I get more pleasant imaging (due to having a Reflection Free Zone) while still experiencing envelopment and ambience. It is a mix that adapts to the song being played, so not the same sauce on everything.
The idea stems from quite a while ago with some experiments done in an even smaller space, a car. Back then a member of a different (car audio) forum triggered the interest of what
could be done with a "faked" back drop. I don't mind what others think or feel about it, as I'm in it for MyFi, not specifically HiFi in it's strictest sense as some put it. I like an enjoyable presentation, one that makes me feel I'm right there, at the take/recording itself. It all has to do with one's preference. I prefer having that RFZ (Reflection Free Zone) but need to make up for the energy lost/absorbed.
Much more info can be found in a
long thread. Some reviews from friendly members that visited me can be found there too. Links are present in the first post to make it somewhat easy to navigate. See it as my own version of
experiments Siegfried Linkwitz used to do (may he RIP). Same idea basically, different way of going about it.
On with the subject at hand, sorry for this detour, even though parts of it may spark some interest for a different way of taking on the problems related to what's discussed in this thread. As said; the room will dominate a lot that's heard at the listening position. So I treat my system, room + speakers, as the query to solve. That's why I picked these specific speakers and do what I do. It's all DIY, which makes me able to cater to my wishes.
(*) = relatively speaking. There's more going on not related to this discussion.
