Location of compoments.

My new rack is 32 inches tall and 65 inches wide (the top is about a foot below my tweeter) and the front of the cabinet is about 18 inch behind the front baffle of my speakers. My speakers are fairly far apart and around 2 foot away from the rack which is centered. The bottom of my 75 inch flat screen is about the same height as the top of my speakers. It's about 3 feet behind the front of my speaker. I should probably try covering it to see if it makes any difference.

Putting the gear to one side would not work well for me with a single stereo amp.

Hey... another Audiogoner with a Marshall half-stack in his listening room! 

I also go with the short speaker cables from monoblocks and long interconnects to my racks that are on the right side of the room.  Galen Carol, a TX audiophile dealer always recommended such a setup.  I think having open space between the speakers helps with soundstage depth and imaging; my amps are nearly hidden behind my Apogee Duettas (my system is pictured in the Virtual Systems section).

Above all on the list to getting better sound is to have a ladder next to your head 

 I do gear to the side for one system,

@mulveling , do you go with long speaker wires or long interconnects?

shouldn't those horns not be next to the ceiling and wall?
