Where to locate Equipment?


I have seen countless setups with the AMPS, DACS, Turntables, etc, all positioned BETWEEN the speakers.  Years ago, I thought this was taboo, and I have always had my equipment to the left of my listening position. I can see the benefits, using short speaker cable runs, etc, but, was/am concerned about that occupied center spot affecting listening quality in some way? 
My room is a rectangle, approximately 19x14x8, carpeted, drywall, pretty normal room for a 2ch system.  Any replies, comments, suggestions are welcomed. Have been away from the hobby for about 20 years, and finding many things have changed during that time.  Thanks in advance.

Directly behind my speakers is a large closet. If my house had more storage space, I'd clear out the closet, move electronics, and run speaker wire through the wall. It would look better too. The sound works as-is so I don't sweat it too much.
The best location for a component rack is in front of the house by the curb. Be sure to use Craig's List or it may be there a while.
I have moved my rack off to the side. My listening space is small and it doubles as an office.

I am trying to convince my kids to let me take over the game room they do not use. 
Use long XLR cables from your gear kept on the side to the amp in-between the speakers. If you have well designed gear the XLR quality should not make that much of a difference so you can use cheaper (but very good) XLR, such as pro XLR's. You can then get better and shorter speaker cables which I find make a huge difference.

My XLR's from the preamp to the amp are 15 feet (could be a longer If need be), and my speaker cables are only 3 or 4 foot. XLR's cost $250 and the speaker cables $3500.
