Best combination of HT and sound

I currently have a Marantz 8000 series that I purchased decades ago. It has power supply problems now but I loved the musicality of this receiver. Needless to say, as a past audiophile, I am in the position to upgrade my system. Looking for either a good HT system that allows 4K pass through with a good phono preamp. I've seen the Denon 960 and 2700 but really looking for a good 7.1 amp and pre -amp combo. Currently using Paradigm speakers for surround. Will change this if the right speakers fit my profile. Want low profile speakers. Any and all suggestions and comments welcomed
