It you do not have a turntable it makes no difference sonically where you put your equipment. From a cable perspective, it is best to keep mono amps right behind the speakers keeping the speaker cables as short as possible running balanced cables to the amps.
You want to keep turntables as far away from the speakers as possible
Ideally in another room.
I do not like equipment between the speakers for aesthetic reasons. I do not want to see cables and complexity. My system doubles as a theater so I have a big screen in the middle. The equipment is in a custom built in cabinet to my left side. Seated at the listening position you can not see a single wire. Perfect.
