Putting your components inbetween your speakers.

@gdhal Thank you for your kind words. 

@erik_squires  I agree, it certainly makes a difference, however people may not always be able to keep the space between the speakers empty. Basically any "fill-in" between the speakers will act as a diffuser, so sometimes it may not be desirable, other times it may improve the imaging, when compared to an empty reflecting wall. The only way to find out is using your ears. In general I would say, try to keep the objects in the space between the speakers below ear height. That way you can run shorter cables, (shorter=better) and most likely still keep good imaging.

@han_n No, this is just a test, but diffusers are different than absorbers, and this is mostly an absorber tets. :)

My last tip: Your imaging improves in the dimension you improve room treatment. If you want more depth, deal with thigns behind the speakers and behind your head. More height? fix the ceiling and floor. More width? Sides.

Best,

@erik_squires  No disagreement about diffusers and absorbers, I know the difference, but here it was about putting your equipment between the speakers. As the equipment will never act as an absorber, it will diffuse the sound. I also agree that room acoustics will have a much bigger impact on the sound than what most people are aware of. Dare to experiment and you wil find out that with moving things around (at no costs but a bit of sweat) you may find a bigger improvement than investing in more expensive equipment. Unfortunately, most people don't have a dedicated studio for listening purpose, so moving things around is often limited by the lovely wife... 

According to Jim Smith , the author of the book, Get Better Sound, he states that you should not place your gear between your speakers.  It will have a negative affect on imagining.  FYI.
