I don't have the disposable income at the moment for the 70 or the 90, but I'm interested in both. I will wait until I know HDMI 2.1 without issues is included. I've been waiting for a new pre-pro for a long time. I'm on my second or third intermediary AVR while I've been waiting for something with all of the features I'm looking for. I had an Integra pre-pro at one point, and I miss the balanced connections. I can't say how much they affected the noise floor versus just better design overall, but I will always prefer the click-in connection point to that of RCA. Everything else in my system is close to what I want (as always, FOR NOW), with the pre-pro/AVR being the final piece. I just need to save up some money again!
