I'm another of the stuff between the speakers culprits. I have a dedicated listening room but it's small. One wall has a door in it two walls are pretty much entirely covered with record and CD storage. So there is nowhere else for the hi fi to go except between the speakers. The wall between the speakers has the window in it, so the record/cd storage can't be moved to there.
I also have big speakers in this small room - and they do work well following careful attention to setup and room acoustics. (I do have some pictures on the wall with the door and could probably make a small improvement by eliminating them and putting in some treatment. But I enjoy looking at the pictures. Would I do it differently in a lager room - naturally. But I'm not going to move house for the sake of the hi fi - or eliminate my music collection to make space in the room to move the hi fi from between the speakers.
