This will be my first time putting together a quality av system. I am not a big tech guy, photographer by trade. Any and all help greatly appreciated. I am currently designing my home theater with a 4k HDR tv in mind. I am thinking of a Sony or Samsung 65" or 75". Any thoughts? I plan on having all of my AV gear in a closet which will be a 55' conduit runs to my Sanus CFR2127 rack. I have purchased a Yamaha Avenge RX-A2060 receiver. My speakers will be 3 Martin Logen Edge in wall speakers for my front left, center, and right speakers. I have 2 Elecromotion R speakers for the ceiling to be my rear left and right. I am plaining on using Audioquest FLX 14/2 speaker wire run in conduit to my (TV wall) and conduit to my in ceiling speakers. Question 1: Can I run my tv wall speaker wire in the same conduit? From my 4k TV to receiver I plan on using the Celerity fiber optic to HDMI using the Fiber optic Gateway Transmitter and Gateway Receiver. Question 2: has anyone used these? I want to control all my devises using the Niles MS 120 flush mount info red sensor connected to Cat 6 or cat6A cable thru conduit to my AV closet connecting to the Niles MSU250 info red repeater to control all of my equipment. Yamaha receiver, apple tv, comcast cable box, cd player, and blue ray player. Any thought? Should I run CAT 6, 6A, or 7? Is 3/4" conduit big enough for 3 runs of ethernet cable? 11/2" for speaker cable?
