I thought it might be helpful to show how I solved some wiring issues for my setup. My living room is on the 1st floor with 3 outside walls and no way into the ceiling above the room. I had wires exposed for a long time, but it was finally time to do something about it. I decided to run my wires behind some crown molding.
I made wire hangers out of 18 gauge steel wire that look like this.
The end loops over the screw head, so I can add the wires and lock them in after all the hangers are in place. They fit behind the crown like this.
I put a bunch up.
I ran all my wires around the room and let them hang down where they would be dropped into the wall.
Then I ran them vertically through the wall. The top holes would be hidden by the crown.
Then I finished the wall plugs.
Then I connected everything to make sure it worked before putting up the crown.
I am running 5.2 with speakers I bought 18 years ago.

Last year, I finally replaced my 18 year old Denon AVR3802 with an Outlaw Audio Model 976 Pre/Pro and an Outlaw Audio Model 7000x Amplifier. It was a significant improvement going from the Denon to the Outlaws.
