Yes, I have heard the 745. I just sent it back to them. It’s a feature rich receiver far and above anything else in its price range, and then some. The only problem with it, is it’s plagued with bugs. Not just the one I had either. HK is working on a firmware update to address the bugs, but they’ve been saying htat for six months now. And that’s to rectify the issues that they admit the receiver is having. Good luck with the rest of the issues, like processing HDMI multi channel uncompressed PCM. I’m also pretty disipointed in its build quality. Instead of going off the 7xxx line amps and adding new features, HK dumped that line. HK tech support is very good, fortunately. I’m guessing they took their QC budget and redirected it to tech support.

....I'm not bitter.
