I don’t have one but I remember around launch time, the guys that were getting them seemed to be happy, with lots of hype. I would guess maybe a dozen members have one. Maybe less?
My experience with many reviews/products is that many times, users are stoopid, and blame it on the products. RTFM!!!!!! Lol. So if you’re patient enough to sort through good AND bad reviews and boil them down, you should be able to make a good choice.
IMO, as long as you set your expectations accordingly, you’ll probably enjoy the NAK fairly well. Just know that it’s actual Atmos capability will not be as good as a discrete system. However the overall surround presentation could be pretty good.
