Dedicated Home Theater/Listening Room Suggestions

Just curious to know if anyone would like to share their experiences with wiring and designing a dedicated listing room for 2 channel as well as home theater. I will soon be moving into a new home where I currently have a dedicated listening room roughing out in the basement.

A few questions that come to mind are; Is it worth running separate power circuits for power amps and digital sources from the panel? Anyone know of any info online that maybe of value to this project? What should I use on the ceiling?

Any help would be greatly appreciated.

Thanks in advance.
