This current Media Room is the result of three previous media rooms, countless stereo systems, and quite a few years of continued planning, growth, and tweaking :-) I still have a way to go and have several upgrades/tweaks planned for the upcoming months. It is a labor of love, and many hours of listening and watching have been enjoyed here. My goal was for the media room would be a dual-purpose space for both listening to music and watching movies. For the most part, I feel I have succeeded. 

Goal two was to build a room that would both indulge my hobby while still providing an actual space to listen to music and watch whatever comfortably and enjoyably. 

We moved into our current house in 2009. The Media room was custom built over the oversized two-car garage and is 18.5' x 22.5' with 9.5' ceilings at the center. All four walls have about a thirty-degree tilted-in soffit area where the side and rear surrounds are mounted. The ATMOS speakers are ceiling mounted, and the front speakers are freestanding. The builder/contractor pulled the wiring for the surrounds, and it is 14 ga. I pulled the ATMOS wiring myself, adding it later (now, THAT was a lovely job!). The front speakers (LCR) are wired with my take on "audiophile" speaker wire.

• I've rack mounted all three Parasound amps and the Marantz Pre/Proc
• Everything else is on a fixed shelf or, in the case of the mixer and the computer, on a sliding shelf.

Balanced cables between Pre/Pro and Amps - Mogami 3080 cable and Amphenol XLR's built by "World's Best Cable."

HDMI by Blue Jeans Cable
 35' BJC Series One - Projector
 6' BJC Series One - OPPO UDP-203
 all other HDMI are 3' or 6' BJC Tartan 24 Series cables

I BUILT all of the RCA-type interconnects (well, most of them anyway) using Belden 1694A cable and solder-type REAN RCA connectors.

Speaker Cables

LCR - Belden 5T00UP 10 Gauge x 2 bi-wire/bi-amp with locking banana plug connectors and spade connectors at each pair on both ends. I built an "Audiophile" speaker cable that can be seen in the room pics.

They do look VERY nice and "audiophile-ly"! As good as they look, it made zero difference in the sound over the simply separate 10 ga wire pairs. 

I also DIY'ed Cable elevators. Not for any expected improvement in the sound, but to display my speaker cables :-)

Speakers in-walls and in-ceiling use Belden 14 Gauge contractor-grade speaker cable

As I said, this room has afforded us much entertainment and enjoyment :-). Of course, I'll be forever tweaking and experimenting, but that is just because that adds to the fun for me!

Happy Listening!!
