No, you have it right except I prefer to have the amp in a separate stand instead of in a rack. I am a believer in not having anything sticking up between the speakers, but I like to keep my speaker wire runs short, so I place the amp between the speakers on the floor with everything else on the side wall. Besides, turntables do not sound their best between speakers. 2/3 of the way down the side wall is where you want your turntable.
Placement of components in audio rack
I currently have from bottom to top, on individual shelves in an open rack stand: amp, pre-amp, CD recorder, CD player, turntable on top. This is probably a pretty normal set up, but wondering if anyone has messed around with the order and found any significant improvement? Also, I plan on adding a tuner to the mix. My past experience has been to put the tuner away from all other components for best signal; like in another part of the room with long interconnects. Thoughts?
