Roxy, you have tried the rack off to the side and didn't notice much difference. I suggest you go with that as every system and room combo is different. FWIW, in my case, relocating my rack from between my speakers to the side wall made a noticeable improvement in soundstaging. Even though I had to replace my speaker cables with another pair (same brand) that were twice the length, the sound of my system was definitely better. Hearing is believing.
Equipment Rack Between Speakers...Good or Bad
This question came up in another current thread and I thought it would be more appropriate to start a new thread to address it. My rack is between my speakers. In the past I have tried it off to the side and didn't notice any sonic advantage. I have seen in in the past that there are some strong feelings on this subject, and I am interested in hearing what everyone has to say.
