my cals were pretty accurate on distances, except the one surround. i'll cut a board to sit on the couch and reline the other chair next time to get it perfect. I'm running an xpa for mains and upa for surrounds, so i understand the gain difference. i'm using some 16ft rca for RCL right now, and there's a bit of noise. i have 10ft xlr on order currently. Also, rushed the cal so we could watch a movie before bedtime. going to redo the front panels as i had to move the equipment now too.
I know the picture doesn't show it too well, but i have mounted bass traps in the corners of the front wall, and roughly (very roughly) attached 705/703 to the front wall with some of those insulation pins and used all the scrap pieces of cloth leftover to mask it in black. i also stapled the cloth to the wall to help support everything. IRL it looks like crap, but i never built the room for looks anyway and it's behind the screen.
