Speaker upgrade around 100k retail

At $50k the Snell A7 are on ebay sold for $7k, Could go with momentum monoblocks for them  put the rest in gear(Illusions)

I would qualify your request by asking for people that have actual experience with the speakers, not just hearsay or reading a review. I could care less about somebodies opinion if they actually haven’t heard them.

I’m with the OP, I wouldn’t ask a dealer for their opinion. Most if not all dealers will only recommend what they carry not what might be best for their existing equipment/room/taste. Now if you wanted to stay in the same line of speaker then ask a dealer that carries that brand 

you font say how much space you gage; but, if you’ve got enough, for WAY less than  hundred large; why not get four Klipsch corner horns and two large Klipsh horns for front and rear center channels. Then add a pair of big, mean subwoofers, maybe something along the lines of the largest HSU Labs subwoofer, or if your even barely competent with basic hand tools, try the “El Pipo” from free plans and videos on the net. When I was in my DC and SFO houses, I made myself a pair of El Pipos. We had a forty-four foot long by 16 feet wide open living room and dining room open area. Even with the windows open, you could still feel the air pressure in the room puff noticeably when the bass or synth player hit a low fundamental.
