Update on my current setup.
A year ago today, I've had dedicated circuits added to my room. Custom box that my electrician came up with, so I didn't have to add individual boxes into the wall itself. Perfectly relocatable with minimal repair to the wall if ever needed. Plus, if I wanted to relocate the audio equipment into the closet nearby, I can do that due to the attic space being behind this wall that is accessible from an access door in the closet.
Circuits are: Three 30A 120V, One 30A 240V, and Three 20A 120V. One of the 20A 120V circuits are ran with 10AWG romex, so if I ever needed to upgrade it to a 30A 120/240V circuit in the future I can. The other two 20A circuits are 12AWG romex. The 30A 240V is for the SpeakerPower SP-12000 I want to buy in the future.
Shortly after that, I had purchased my Marantz AV7703 and a couple of pairs of
KEF HTS3001 4" Coaxials for Dolby Atmos. However I've changed my layout again very recently. I've taken the Volt-6 down from the back wall, and built another pair of Volt-10 LX and put them at the same ear level as the side Volt-10 LX speakers. This move alone made really made a difference, having the speakers at ear level.
Then I have built acoustic panels, using Spoonflower to print my characters onto fabric for me and had put them on the back wall. I still need to get some panels made up for the front of the room for the first and second reflection points. For these I may use standard black fabric. Still trying to decide on some mounting solutions.
Then I've got some 13/16" Unistrut channel and bolted it to the ceiling joists and had a local machine shop make me some brackets so I could use my Volt-6 speakers (Having built a second pair) to use for my overhead channels. I still need to get the wiring properly situated but I think it's turned out great so far!
Other bits of update, would be the Impact 6x2 Matrix Component Switch I got for my older game consoles, so I could connect my PS2, GameCube, and original Xbox up to the XRGB-Mini Framemeister for easier switching needs.
Then I modded my SNES Mini (Not the SNES Classic) for an RGBs mod and TOSLINK mod, for which I also bought the Blackbird 4K Series HDMI Audio Inserter to go between the XRGB-Mini and my 8x1 HDMI switch. So I can switch between HDMI audio pass through and TOSLINK insertion for the game consoles that currently send digital audio. (PS2, Original Xbox, and SNES). So I don't have to worry about the analog audio output. (Which is then going through an ADC within the XRGB-Mini.)
Here's some pictures of the SNES Mini:
Also a video, using the capture setup for it:
I've even ended up building an HTPC for my PC gaming needs on my home theater system as well. Using a Thermaltake Core V21 chassis. Using a Core i7 7700k processor, ASUS ROG STRIX Z270G motherboard, MSI GeForce GTX 1070 graphics card, 32GB RAM, M.2 SSD 512GB. I also have my AverMedia Extreme Cap U3 connected to this as well. Using Zone 2 HDMI out of my Marantz AV7703 pre-pro.
Another addition to my setup would be my SCART switch, the gscartsw v3.4.
The next step is to get my nearfield subwoofer build completed, which use the SI HT-18 V2 drivers, which will be powered off the iNuke NU6000 DSP.
The two JBL 2242 drivers holding my center channel/TV will be going to a new home soon, since a friend of mine will be buying them off me. So I'm trying to figure out what to replace them with specifically. So far leaning towards a quicker solution by getting another pair of dual opposed Daytons put into place. That or splurge for a pair of dual opposed 21" drivers. Latter will be much more expensive, but will be a bigger upgrade. So we'll see.
