Hi looking for some opinion. I’ve had the Denon x7200wa for a few years and was thinking is it worth upgrading. I have Monitor Audio Silver 8 L/R/C BK XXLLS400 Sub Kef T Series rears and PSB Imagine XA atmos speakers. Budget of about £800- £1000 HDMI 2.1 slot is preferred. Is there anything in that price range that would be considered a upgrade or am I better sticking with the x7200wa. Many thanks.
