My system is not very esoteric. Our home was gutted by Hurricane Ernesto and when we renovated it we incorporated a surround sound system in the living room. I previously had large floor standing Canton speakers but my wife wasn't very happy with them in the living room. Here is the current setup:

The front three channels are Thiel Powerpoint 1.2 speakers. Our living room is long and these speakers project into the room well:

The sub is a McIntosh, the four surrounds are Thiel Higher Plane 1.2's:

The display is a Pioneer Kuro 55". We replaced the fireplace with a custom audio cabinet that holds the equipment out of view, including a Denon AVR 3808CI, LG Bluray player, Denon DCM 390 cd player, Xbox 360, AudoiControl AEQ26 Architechtural Equalizer, Universal Remote MSC-400 Master System Controller with RF control, XM Radio receiver, and miscellaneous accessories. Cabinet doors closed, the system is unobtrusive, although my wife thought the Thiel front speakers looked a little George Jetson. She's used to it now.
Overall, I'm very happy with the system. The audio is very impressive, the Thiels do their job without sounding like in-ceiling speakers. The Pioneer has a nice picture. The system is unobtrusive enough to please my wife's aesthetic eye and has good enough audio and video to please my inner child. For the rest of me, the furniture is Ekornes Stressless Paradise and Vision. Each seat in the sofa reclines, headrests are adjustable, so it is a killer nap setup, too
