Thanks guys. I'll try to respond to all the comments and questions from the last few posts. Bear with me.......
The Canton's should arrive today and the Yammy RX-A3080 should get here Friday. I already have the SVS PC-2000 sitting here in the box as well. From a 75" size standpoint, the only two things are are close to the cost of the 65" 950H are the 75" TCL 8 series for about $100 more and the 75" 900H for about $500 more. The 950H in 75" is about $1100 more and the Q90 in 75" is double.
The space isn't a dedicated theater room, but we do have solid wood blinds that will get the room dark enough during the middle of the day for most any TV to be visible. The viewing angle isn't super important, but we do have a wrap around sofa so some spots are off center.
I had these posted in the sub thread I started when picking the PC-2000 but it shows the room. It's not very deep but from head to back of that alcove where I plan to hang the TV is as much as 13 feet. The Cantons will sit on the floor under where the white deftechs are hanging. (I ordered gloss black Canton's by the way as my wife didn't like the gloss white finish). I'm planning to replace that red cabinet with something like a salamander designs synergy 237 cabinet and use it to hold my equipment and the canton center speaker on top. That TV pictured is a 65" samsung Q80 that I returned to get the sony when I found out it didn't support dolby vision. The alcove measures wide enough for a 75" to fit with a few inches to spare though. As you can see, it's a long room with the viewing area on one end. That portion is 12' deep and 16' wide (not counting the alcove). The alcove is 19" deep and 67.5" wide, so we are talking a very tight fit on a 75" TV. (a 77" model wouldn't fit)
Gaming is not a priority for me personally, and my son keeps saying it isn't for him as he prefers his computer for gaming most times. That said, I have this feeling that he will pop up next year and want a next level gaming platform when they really hit the market, but who knows. I don't think the Yamaha 3080 is capable of 4k/120 hdmi 2.1 either. Regardless, if I upgraded size but downgraded models, the X900H sony is supposed to get the 2.1 via firmware upgrade, but I keep seeing posts about jailbars and other issues with the x900h tv's. If I move to the TCL 75" it doesn't look to support 2.1 at all or eArc. If I move back to samsung then I loose dolby vision. The new 2020 Vizio 75" PX series may be the best option to check the most boxes but I'm not sure how it really compares and it's not available anywhere that I can find either. Ugh....................
I've been using the upper front deftechs as front height speakers with my onkyo 636. Have been looking at the canton 500 atmos speakers that can sit on top of the floor speakers and am wondering if they would replace the upper speakers and if so would they be best on top of the floor speakers or hanging where the deftechs are? I'd like to get all matching canton's at some point.
