Thank you in advance for your thoughts.
Frankly, either one will give you an amazing image. The NX7's extra iris gives it significantly more contrast, and in the dark basement on that size and gain of screen, this would be very noticeable, particularly on darker scenes. With your size of screen you can take advantage of the P3 color filter and get the full P3 range and still have more than enough light to make both SDR and HDR pop. So basically if you want better contrast and color, go with the NX7. Otherwise either one would do just fine for you.
Keep in mind, the NX5 will still have better contrast than a Sony or Epson, and neither of these is a slouch in terms of contrast. Some people put a lot of weight behind contrast though, and if you are one of them, then you would probably be far happier with the NX7.
You have a tough choice there because $2k is a big difference for some added contrast and color. Either one will work for your setup. It's like choosing between a top end LCD and an OLED TV, both are pretty great, but it's a question of how much that added pop of better contrast and color is worth to you. Frankly if I had a "normal" sized screen I would have had a tough choice between the two. I went with the NX7/RS2000 because I needed the most possible light I could get. I also figured if I were going to drop a big pile of cash, I wanted the best I could get. If the NX9 had been about $3k cheaper, I would have gone that route just because the bigger lens got more light to the screen. Everyone has their budget limit.
One more thing, if you wanted an NX5 right now and are in the U.S., dealers have them in stock on the shelves ready to ship today. I'm still weeks out on my RS2000/NX7 that I ordered back in early November, and without a pre-order, it could be June before you could get one.
