What causes imaging or the lack of it

My friend and I both have Innersound EROS electrostats, with only a few differences in equipment. My system has incredible imaging, and his has none! We can move my speakers almost anywhere in posistions in attempt to stop imaging, and its still there. On the other hand, we can position his speakers in every possible position except, hanging from the ceiling and no imaging at all. You can rule out anything to do with the distance between them. the distance to the sweet spot, the toe, etc, etc. We both set up our systems perfectly in accordance with Innersound specs. We are trying to find out just what could be causing the difference in our systems, or why his is not imaging? I dont like equipment listings on threads but,it may be necessary for you to help.

My system - Innersound EROS MK1's with MK2 panels, MK3 bass xover amp, and ESL amp. Pioneer elite DV-05 dvd player as transport, Assemblage 2.6 platnum DAC, and d2d upsampler, Kimber D-60 digital cables amd MIT T2 interconnects

His system - Innersound EROS MK1's with MK2 panels, original bass xover amp and parasound amp for panels. same dvd player, same digital cables, same interconnects. His dac is being utilized through an EAD Encore.

Even if you can explain what creates imaging, it will help us. Thanks....

Imaging is created by the brain. The sound is recorded on two seperate channels with mikes placed approximately where the ears would be; you then hear each channel from each speaker. Since both ears can hear both speakers simultaneously, the crosstalk from left speaker/channel to both ears and right speaker/channel to both ears recreates the 3D image.

Assuming nothing wrong with the equipment, hookup and power, the main cause of loss of imaging or center image is: a) unequal distance from ears to speakers, and b) excessive room reverbations (reflections that do not decay). Even the crappiest component will image somewhat with quality speakers as will the crappiest speakers with quality components.

Usually the speakers are a)too close together...B)have something large between them with a highly reflective surface(bigscreen tele)...or are simply incapable of producing a stable "out of box" image....

Well guys, we discovered the problem. I brought all of my gear and cables to my friends, and swapped it out with his. After all that, same problem! We were at least now, at two conclusions, the room or the speakers. To make a long story short, it turned out to be a defective or weak power supply in one of his Innersound Eros speakers. This was causing slightly less volume from one panel, and almost complete loss of imaging. Thanks for all your advice, it helped us get to the root of the problem.

Steve, you must be a helluva guy to help your buddy out by toting all of your stuff over there like that. I'm glad that you found the problem. Hopefully, Mr Sanders will take care of the problem and your friend will be up in running very shortly. Sean
