Difficult to say, Marantz is a bit vague on how they specify, they quote 80wpc but the power consumption as 420W, so they can't possibly mean "with all channels driven into 8 ohms".
So my guess is your receiver is on reality 50wpc.
Normally that should be enough for a smallish room and playing not excessively loud- but the first thing you could notice is some compression setting in and some lack of deep bass.
Also, Marantz has a bit of a "fat" sound, which may or may not be a good match for the KEF's...
Had a Marantz SR-9600 which did seem to output a slightly fat high bass and low mids exaggeration.
Then, KEF's are very transparent speakers, with excellent staging, but not exactly powerhouses, so look elsewhere if you prefer hardrock or organ played VERY load!
